From ‘British Jobs’ to BSW: How the Fortress Left Surrendered to Hyperpolitics

The Controlled Experiment the Fortress Left Lost

Feb 02, 2026

On 12 May 2025, Keir Starmer stood before cameras and warned that without his immigration reforms, Britain risked becoming an “island of strangers, not a nation that walks forward together.” The phrase landed like a brick through a window. Critics heard echoes of Enoch Powell. Progressive factions howled. Civil society groups demanded retraction. Six weeks later, Starmer apologised. He “deeply regretted” the phrasing, he said. The policy remained untouched.

The policy did more than remain untouched. By January 2026, Labour had implemented what it called the biggest shake-up of the legal migration system in nearly half a century. The path to permanent residency: doubled from five years to ten. The ten-year long residence route, the safety net for workers with complex immigration histories: abolished entirely. English language requirements for skilled workers: raised overnight. An Electronic Travel Authorisation system, mandatory from February 2026, imposing a digital permission barrier on nationals of eighty-five previously visa-free countries. And the care worker route, the lifeline for a sector that cannot function without migrant labour: closed to new overseas applicants. The Border Security, Asylum and Immigration Act received Royal Assent in December 2025 with barely a murmur from the parliamentary left.

This is not triangulation. It is capitulation with a legislative programme. Brown’s ‘British Jobs for British Workers’ was a conference slogan that embarrassed its author. Starmer’s Fortress is an Act of Parliament.

This is the pattern. The rhetoric shifts; the underlying logic persists. From Gordon Brown’s “British Jobs for British Workers” in 2007 through the Lindsey wildcat strikes of 2009, from Maurice Glasman’s Blue Labour project to Sahra Wagenknecht’s BSW, a particular formation keeps emerging on the European left: economically interventionist, rhetorically pro-worker, and convinced that restricting labour mobility is the path to working-class renewal. Call it the Fortress Left. It promises to outflank the far-right by adopting its framing on migration while retaining redistributive economics. It keeps failing. And it keeps returning.

Why? The question matters because the Fortress Left is not marginal. Dan Carden chairs a Blue Labour Parliamentary Group in Westminster. Sharon Graham runs Britain’s largest union on a platform of “fighting employers not the Labour Party.” Mette Frederiksen governs Denmark. Wagenknecht polled ahead of Die Linke in the run‑up to the 2025 federal election. These are not fringe positions. They represent a genuine strategic tendency within social democracy, one that believes the national arena is the only viable site for class politics and that defending borders is defending workers.

They are wrong. But understanding why requires more than moral condemnation. It requires grasping the political conditions that keep generating this response.

The Hyperpolitics Trap

The Portuguese socialist Diogo Machado, writing in Anti-Capitalista, recently drew on Anton Jäger’s concept of “hyperpolitics” to explain the contemporary conjuncture. The argument runs like this: the neoliberal era from the 1980s onward produced a “post-political” settlement. Economics was insulated from democratic contestation. Politics became a technocratic competition over marginal differences within an unquestioned consensus. The working class retreated into private life. Parties, unions, associations all haemorrhaged members.

Then came 2008. The financial crisis shattered the consensus. Mass movements erupted: the indignados, Occupy, the anti-austerity protests. Politics returned. But it returned in a particular form. Not through renewed collective organisation, but through individualised, affective, ephemeral engagement. People became cognitively mobilised for politics without joining anything. They consumed political content, argued online, attended occasional demonstrations, then drifted away. Jäger calls this “low” politics: low cost, low entry, low duration, low commitment. High engagement, minimal organisation.

This is hyperpolitics. The public sphere is repoliticised, but this repoliticisation leaves untouched the atomisation produced by neoliberalism. Machado puts it precisely: “an illusion of participation that leaves untouched the relations of power that organise society.”

Here is the trap. Hyperpolitical conditions favour political projects that demand nothing sustained from their supporters. Projects that offer emotional satisfaction without organisational commitment. Projects that can be consumed passively, that fit the rhythms of algorithmic feeds and dopamine cycles. What fits these conditions perfectly? Nativist appeals. “Defend our jobs from foreign workers” requires no collective action, no solidarity across difference, no long-term commitment. It offers immediate affective satisfaction. It can be expressed in a vote, a tweet, a slogan on a placard, then forgotten until the next crisis.

The Fortress Left represents social democracy’s adaptation to this terrain. Unable to rebuild the dense organisational infrastructure that sustained the workers’ movement in its classical period, unable to do the patient work of constructing solidarity across ethnic and national lines, it reaches for the shortcut. It competes for nativist affect while retaining some redistributive content. The result satisfies no one. It legitimises the right’s framing while offering a watered-down version. It wins neither the committed left nor the genuinely xenophobic. It demobilises rather than organises.

Lindsey 2009: The Template

The pattern was established before anyone had theorised hyperpolitics. January 2009. The Lindsey Oil Refinery in North Lincolnshire. An Italian contractor, IREM, wins part of a subcontract and announces it will bring its own workforce from Italy and Portugal rather than hiring locally. The workers are to be housed on barges in Grimsby docks, transported to site on segregated buses, kept separate from the existing workforce and its union structures. On 28 January, stewards learn that IREM will employ no British labour. The walkout begins that afternoon.

Within days, solidarity strikes spread across eleven plants. Three thousand workers out at Grangemouth, Wilton, sites across the country. The slogan that emerged on the picket lines was Gordon Brown’s gift to the movement: “British Jobs for British Workers.” The phrase he had deployed at the 2007 Labour conference, reaching for patriotic resonance, now appeared on hand-painted banners carried by workers the political class preferred to ignore.

The left fractured immediately. The Socialist Workers Party saw a movement tainted by nationalism, a gift to the British National Party, and largely absented itself. The Socialist Party, through strike committee member Keith Gibson, argued the opposite: this was a fight against the “race to the bottom,” a struggle to defend collectively bargained conditions against the European Union’s Posted Workers Directive. The slogan was “reactive confusion,” Gibson insisted, not the essence of the dispute. The SP pushed successfully for demands that reframed the struggle: all migrant labour to be unionised, foreign workers to receive the same NAECI-mandated pay as everyone else, no segregation of workforces.

The strike won. By 5 February, Total had conceded 102 jobs for local workers and parity on conditions. When management tried to impose redundancies without consultation in June, a second walkout forced complete capitulation within two weeks. In purely industrial terms, Lindsey was a victory.

But what kind of victory? The SP’s framing was coherent: defend the rate for the job, organise all workers regardless of origin, oppose the legal framework that allows employers to play national workforces against each other. This is orthodox trade unionism applied to the conditions of EU labour mobility. Yet the imagery that dominated media coverage, the imagery that entered collective memory, was “British Jobs for British Workers.” The substantive demands were forgotten. The slogan endured.

This is the Fortress Left’s recurring problem. It enters disputes with defensible positions about collective bargaining and wage floors, but it cannot control how those positions circulate in a hyperpolitical media environment. The nuance dissolves. The nationalist residue remains. And that residue becomes available for appropriation by forces with no interest in trade union organisation at all.

Blue Labour: The Theory That Built Nothing

Maurice Glasman understood something about the post-2008 moment. His Blue Labour project, launched the same year as the Lindsey strike, offered a theoretical framework for the discontents the dispute had exposed. New Labour had failed, Glasman argued, because it had abandoned the working class culturally even as it sometimes defended it economically. It had embraced an “aggressive secularism” and a “metropolitan liberalism” alien to the rooted, communitarian instincts of Labour’s historic base. It had worshipped markets and bureaucratic management while letting traditional working-class institutions wither.

The prescription followed from the diagnosis. Labour must become “deeply conservative” in its socialism. It must reconnect with “faith, family, and flag.” It must recognise that concerns about immigration, crime, and community cohesion are not right-wing diversions but essential components of the good life that a socialist party should defend. Drawing on Karl Polanyi’s critique of commodification, Glasman argued for a “post-liberal” politics that would resist both market fundamentalism and statist managerialism in favour of rooted, relational, local forms of solidarity.

As cultural diagnosis, this had some purchase. New Labour really had abandoned industrial communities. The party really had become dominated by a professional-managerial stratum disconnected from its historic base. The concerns Glasman identified were real concerns, felt by real people who had watched their communities hollowed out by deindustrialisation and then patronised by politicians who called them backward for noticing.

As political strategy, Blue Labour was a catastrophe. It produced pamphlets, seminars, Guardian columns, and precisely nothing else. No organisation. No membership. No presence in workplaces or communities. The movement that claimed to value rootedness and relationship existed entirely in the realm of metropolitan intellectual production. Glasman himself was elevated to the House of Lords, that notoriously rooted institution. His followers debated each other in think-tank events while the working class they claimed to champion continued not joining anything.

By 2012, Blue Labour had effectively collapsed, damaged by Glasman’s own comments suggesting Labour should have “an honest debate about immigration” and needed to recognise that people were “worried about” the extent of population movement. The timing was poor; the phrasing worse. But the deeper problem was structural. You cannot rebuild communitarian politics through op-eds. You cannot restore “faith, family, and flag” from a seminar room. The gap between Blue Labour’s rhetoric about the importance of organisation and its complete failure to organise anything revealed the project’s essential bankruptcy.

And yet it keeps returning. In 2025, Dan Carden chairs a Blue Labour Parliamentary Group. The same ideas, recycled for a new generation of MPs from “Red Wall” constituencies seeking a framework for their instincts. “Pro-worker, anti-woke,” the press releases say. Big-government economics plus lower immigration plus rejection of “divisive identity politics.” The policy mix is familiar. The organisational vacuum is familiar too. Blue Labour remains a tendency in search of a movement, a set of positions that cannot generate the social forces necessary to implement them.

The Organisational Vacuum

This is the heart of the matter. The Fortress Left’s recurring failure is not primarily ideological but organisational. Its positions on migration might be defensible or indefensible; reasonable people disagree. What cannot be disputed is that these positions have not produced durable working-class organisation anywhere they have been tried.

Consider Sharon Graham’s Unite. Her election in 2021 represented a genuine break with the Len McCluskey era. “Back to the workplace,” she declared. No more “Westminster-centric” politics. Unite would build power through industrial leverage, targeting supply chains and corporate pressure points rather than lobbying MPs. The “no blank cheque” policy toward Labour signalled a more transactional relationship with the party, focused on delivering for members rather than funding factional projects.

This was promising. And Graham has delivered significant industrial victories. The Unite Leverage model works. Employers have been forced to concede where traditional methods failed. But Graham’s strategic framework also involves a deliberate withdrawal from the political arena. She skipped the 2024 Labour conference entirely. Unite’s engagement with broader questions of political strategy has narrowed to transactional demands on specific industrial issues.

The result, as John Westmoreland argued in Counterfire, is that Graham “absents herself” from precisely the spaces where the Fortress Left’s framing gets established. When Starmer speaks of “islands of strangers,” when Blue Labour MPs push for immigration restriction, when the political weather shifts rightward, Unite is not in the room offering an alternative. The industrial turn, for all its genuine achievements, has left a political vacuum that others fill.

Mick Lynch’s RMT offers a different model but a similar limitation. Lynch became a media phenomenon during the 2022 rail strikes, his plain-spoken class politics cutting through the usual broadcast fog. He articulated a “Lexit” position: the EU’s deregulatory agenda was incompatible with public ownership and workers’ rights; leaving offered opportunities for socialist advance that remaining would have foreclosed. On the specific question of maritime labour, Lynch has campaigned against visa concessions that allow employers to replace UK seafarers with lower-paid foreign workers, framing this as defence of collectively bargained conditions rather than nationalism.

The politics are coherent. But what organisation has it built? The RMT remains a sectoral union in declining industries. Lynch announced his retirement in January 2025. The “Enough is Enough” campaign he helped launch in 2022, which briefly seemed to promise a new vehicle for class politics, produced rallies and then faded. The gap between Lynch’s media profile and any lasting organisational legacy is the hyperpolitics problem in miniature: high engagement, high visibility, minimal durable structure.

What Hyperpolitics Explains

Return to Machado’s analysis. Why does the far-right thrive in hyperpolitical conditions while the left struggles? He identifies several factors. The right’s programmatic ambitions are modest: it does not seek to transform social relations but to redirect state violence toward designated enemies. It is compatible with atomised, individualised social life; indeed, it reinforces atomisation while claiming to build community. Its message fits algorithmic circulation: simple, emotional, requiring no sustained engagement.

The left cannot compete on these terms without ceasing to be the left. It cannot abandon programmes of social transformation. It cannot accept atomisation. It cannot offer purely affective satisfactions that leave existing power relations intact. The left requires what Machado calls “dense” politics: sustained commitment, ideological education, the patient construction of solidarity across difference.

The Fortress Left’s error is to imagine it can split the difference. It accepts the hyperpolitical terrain as given, competes for nativist affect, but retains enough redistributive content to distinguish itself from the far-right. The strategy fails because it misunderstands what the far-right actually offers. People drawn to nativist politics are not primarily seeking economic redistribution; they are seeking the affective satisfaction of belonging to a community defined against outsiders. The Fortress Left cannot provide this satisfaction as effectively as the genuine article because it remains committed, however weakly, to some form of class universalism. It loses the internationalists without gaining the nationalists.

Meanwhile, the organisational work that might actually rebuild working-class power goes undone. The Fortress Left’s energy flows into defensive manoeuvres: repositioning on immigration, triangulating against the far-right, managing media narratives. None of this builds unions. None of it constructs the community institutions that Blue Labour rhetorically celebrates. None of it develops the cadre of organisers who might do the slow work of constructing solidarity across ethnic lines.

The Danish Model: Success That Isn’t

The Fortress Left’s defenders point to Denmark. Mette Frederiksen’s Social Democrats, they argue, demonstrate that combining left economics with immigration restriction can work. Frederiksen won. She governs. The Danish far-right has been marginalised. What more proof is needed?

Examine the model closely. Frederiksen’s strategy involved adopting positions to the right of her country’s existing far-right on asylum and integration. “Zero asylum seekers” as an explicit ambition. The “ghetto law” prohibiting immigrants from concentrating in certain housing areas. Confiscation of refugees’ valuables. Reduced welfare benefits for non-EU migrants. Deportation schemes. The rhetoric of “protecting Danish values” deployed without irony by a party that once understood those values as solidarity and universalism.

Did it work electorally? In a narrow sense. The Danish People’s Party collapsed. Frederiksen formed governments. But research on the Danish case reveals a “zero-sum game” dynamic. The Social Democrats gained some anti-immigration voters from the right. They lost pro-immigration voters to other left parties: the Socialist People’s Party, the Red-Green Alliance, the Social Liberals. The net effect was minimal. What made it viable was Denmark’s coalition system, where lost votes to left competitors still contributed to potential governing majorities. In a first-past-the-post system like Britain’s, the same strategy would simply haemorrhage votes in different directions.

More damaging is what the strategy requires to sustain itself. The permanent rightward ratchet. Each electoral cycle demands new proof of toughness on migration. Each accommodation to nativist sentiment normalises the next. The “ghetto law” becomes the jewellery confiscation becomes the Rwanda deportation scheme. There is no stable equilibrium. The far-right can always outbid you because it faces no countervailing pressure from an internationalist base. The Fortress Left, retaining some residual commitment to solidarity, cannot follow where the logic leads. It is perpetually outflanked by forces willing to go further.

And what has Frederiksen’s Denmark built? Not a renewed labour movement. Not stronger unions. Not deeper community organisation. Danish social democracy governs, but it governs a society no less atomised than before, with a working class no better organised, and a public discourse permanently shifted rightward. The far-right parties may have shrunk, but far-right ideas have triumphed. This is victory?

Wagenknecht’s Ruin: BSW as the Fortress Left’s Definitive Failure

If the Fortress Left needed a laboratory experiment, Sahra Wagenknecht obliged. The Bündnis Sahra Wagenknecht, founded in January 2024, was the purest distillation of the project this article anatomises: left economics fused with immigration restriction, anti-establishment rhetoric married to cultural conservatism, the whole edifice constructed around the charisma of a single individual who promised to win back the workers the left had supposedly lost to the AfD. For approximately nine months it appeared to work. BSW won 6.2% in the June 2024 European elections. In September, it took between 11% and 16% in the eastern state elections in Saxony, Thuringia, and Brandenburg. Commentators across Europe took notice. Here, at last, was a left that spoke the language of ordinary people rather than metropolitan activists.

Two years later, BSW is polling at 3-4% nationally: below the 5% threshold, heading for extra-parliamentary irrelevance. Wagenknecht stepped down as party leader in November 2025. The party’s flagship governing arrangement, the SPD-BSW coalition in Brandenburg, collapsed in the first week of January 2026 when Deputy Minister-President Robert Crumbach and two other BSW ministers quit the party. Crumbach’s verdict was blunt: BSW was ‘unfit for the responsibilities of governing.’ Premier Woidke terminated the coalition and began negotiating with the CDU instead.

What happened next deserves to be etched into the memory of every activist tempted by the Fortress Left’s siren song. The remaining rump BSW faction in Brandenburg, stripped of its ministers, voted unanimously with the AfD on a motion to dissolve the state parliament. The party created to steal votes from the far right ended up voting alongside it. This is not irony. It is the structural logic of the Fortress Left: once you accept the right’s framing on immigration, once you concede that migrants are the problem rather than capital, you have no principled ground on which to resist convergence.

The decomposition is general. In Thuringia, where BSW sits in coalition with the CDU, the party’s own finance minister accuses the federal leadership of ‘Stalinist methods.’ In Saxony-Anhalt, nearly half the state executive has been voted out. Internal warfare rages in Hamburg and Bavaria. The February 2025 federal election delivered the cruelest possible result: 4.981% of second votes, missing the Bundestag threshold by fewer than ten thousand ballots. A personalist project, a Bonapartist formation built on the celebrity of its founder rather than democratic structures or programmatic coherence, is decomposing at the speed such formations always decompose once the founding charisma ceases to deliver victories. Aufstehen, Wagenknecht’s earlier attempt at movement-building in 2019, collapsed within months. BSW lasted slightly longer. The pattern is identical.

Five German state elections in 2026, beginning with Baden-Württemberg on 8 March and Rhineland-Palatinate on 22 March, will now test BSW in precisely the western states where it has no activist base, no organisational infrastructure, no roots in the working class it claims to champion. Current polling puts BSW at 3% in Baden-Württemberg. The party’s trajectory is clear: from 6.2% to 4.98% to 3%, each data point steeper than the last.

And the AfD? The party that BSW was supposed to undercut? It sits at 25-27% nationally, having overtaken the CDU. The Fortress Left did not merely fail to build a durable alternative. It failed to achieve its own stated objective. The far right is stronger, not weaker, for BSW’s intervention.

The Controlled Experiment: Die Linke’s Vindication

History rarely provides controlled experiments. The BSW-Die Linke split is as close as we are likely to get. Two parties emerged from the same organisation in 2024, facing the same electorate, operating in the same political conditions. One pursued the Fortress Left strategy: immigration restriction, cultural conservatism, the attempt to outflank the AfD on its own terrain. The other refused. Die Linke lost its most recognisable figure, haemorrhaged members, and was written off by every serious commentator in German politics.

Two years on, the results are in. BSW: 3% and disintegrating. Die Linke: 10% nationally and growing, with 81,200 members, its highest figure since 2010, surpassing even its post-reunification peak. Among voters aged 18-29, Die Linke is now the most popular party in Germany. In Berlin it polls at 19%.

The catalyst was precise. In January 2025, the CDU pushed immigration legislation through the Bundestag with AfD support for the first time. Heidi Reichinnek, a Die Linke deputy, delivered a denunciation of this collaboration that was watched over thirty million times. The speech did not triangulate. It did not offer a ‘responsible’ left-wing version of immigration restriction. It named the manoeuvre for what it was: the normalisation of fascist politics within the parliamentary mainstream. And it went viral precisely because millions of people, particularly young people, were waiting for someone to say what the Fortress Left refuses to say.

Die Linke’s subsequent renewal was built on this refusal. The party focused on the housing crisis, poverty, and taxing the wealthy. It maintained a clear anti-fascist line. It did not sacrifice internationalism on the altar of electoral pragmatism. The membership surge that followed, from 52,000 in July 2024 to 81,200 by February 2025, was driven overwhelmingly by young activists who recognised that a left which concedes the right’s framing on immigration has already lost the argument that matters.

The Fortress Left’s central premise, that the left must accommodate nativist sentiment or face extinction, has been tested under near-laboratory conditions. The party that accommodated is dying. The party that refused is thriving. This does not prove that internationalism guarantees success; politics is not physics, and Die Linke faces its own contradictions. But it demolishes the claim that the Fortress Left represents realism. Wagenknecht’s project was not realistic. It was a fantasy dressed in the language of pragmatism, and January 2026 is its obituary.

What Mamdani Proves

On 4 November 2025, Zohran Mamdani won the New York City mayoral election with 50.8% of the vote. A 34-year-old democratic socialist, born in Uganda, Muslim, backed by the DSA. His opponent was Andrew Cuomo, scion of a political dynasty, backed by Wall Street, by the real estate industry, by Donald Trump in the closing weeks. Mamdani won by over 200,000 votes. Turnout was the highest since 1969, up 84% from the previous mayoral election.

The hyperpolitics framework predicts this should be impossible. Dense politics cannot compete with low politics in atomised conditions. Organisational commitment cannot match affective satisfaction. Class universalism cannot mobilise like nativist particularism. And yet.

Examine how Mamdani won. His campaign knocked on 3 million doors. It made 4.5 million phone calls. It mobilised over 100,000 volunteers. These are not hyperpolitical numbers. These are numbers from an earlier era of mass politics, achieved in a city of 8.5 million people saturated with algorithmic media and platform-mediated social relations.

The campaign did not ignore hyperpolitical terrain. Mamdani’s team produced viral content. His walking videos, filmed on the street while he talked to voters and vendors, generated millions of views. The aesthetic was contemporary: immediate, personal, visually engaging. But the content was substantive. Mamdani talked about rent control, universal childcare, free public transit, taxing the rich. He explained how he would pay for his programme. He treated voters as capable of engaging with policy detail rather than merely responding to emotional cues.

And on the issues where the Fortress Left counsels retreat? Mamdani advanced. He declared that if elected, he would arrest Benjamin Netanyahu if the Israeli Prime Minister set foot in New York. He committed to blocking ICE raids in the city. He made no concessions to anti-immigrant sentiment, no gestures toward the “legitimate concerns” discourse. He ran as an internationalist, as a Muslim, as a democratic socialist, in a city the political class insisted would never elect such a candidate.

Alda Sousa, analysing the campaign for Anti-Capitalista, identified the synthesis. Mamdani combined hyperpolitical communication techniques with old-fashioned mass organising. The viral videos brought people in. The door-knocking converted attention into commitment. The policy substance gave volunteers something to believe in and argue for. The campaign built organisation while winning an election: 100,000 people who knocked doors, made calls, had conversations with their neighbours about politics. These people did not disappear on 5 November. They constitute a base for future struggles.

This is what the Fortress Left refuses to attempt. It accepts hyperpolitical conditions as given, as terrain that can only be navigated through adaptation to its logic. Mamdani’s campaign demonstrated that the conditions can be contested. That mass organisation remains possible. That class politics can win without nationalist concessions. That the choice between affective politics and dense politics is false, because a campaign can do both if it has something worth saying and people willing to say it.

The Fortress Left’s defenders will object that New York is exceptional. A diverse city, a strong left tradition, a particular demographic composition. The objection concedes too much. Every political situation is particular. The question is whether you attempt to build organisation or accept its impossibility. Wagenknecht accepted impossibility and built a personality cult. Frederiksen accepted impossibility and built a deportation regime. Graham accepts impossibility in the political sphere and restricts Unite to industrial terrain. Mamdani refused to accept impossibility and built a campaign that won.

The Betrayal

Let us be precise about what the Fortress Left betrays. Not merely abstract principles. Not merely the heritage of international socialism, though it betrays that too. It betrays its own stated objectives.

The Fortress Left claims to protect workers from wage competition. But restricting migration does not eliminate the reserve army of labour; it merely shifts its location. Capital moves to where labour is cheap if labour cannot move to where conditions are better. The result is not higher wages but offshored production, weakened unions, and a working class divided against itself. The protected workers in the imperial core benefit marginally and temporarily while their potential allies abroad remain superexploited. This is not solidarity. It is pulling up the drawbridge while the castle burns.

The Fortress Left claims to rebuild working-class community. But its methods atomise rather than organise. A vote for Wagenknecht or Frederiksen or Blue Labour requires nothing but the vote itself. No meetings attended. No neighbours persuaded. No collective capacity developed. The hyperpolitical form contradicts the communitarian content. You cannot restore rooted, relational, local solidarity through media personalities and electoral campaigns. You can only restore it by building actual organisations in actual places, the slow work that the Fortress Left consistently declines to do.

The Fortress Left claims to defeat the far-right by stealing its clothes. But the far-right continues to advance across Europe. The Danish People’s Party shrank; the Sweden Democrats grew. The Front National became the Rassemblement National and kept gaining vote share. The AfD polls above 20% in Germany despite, or because of, mainstream parties adopting restrictionist positions. The strategy does not work. It legitimises far-right framing while failing to satisfy the demand for genuine nativist politics. It shifts the entire spectrum rightward while leaving the left weaker and more confused.

The Communist Party of Britain offers a Marxist-sounding defence of immigration restriction: capital uses migration as a “reserve army” to suppress wages; therefore, controlling migration defends the working class. The argument has a surface logic but collapses under examination. Marx’s reserve army concept describes a structural feature of capitalism, not a policy variable that can be adjusted by border controls. The reserve army exists because capitalism requires unemployment to discipline labour. It will exist regardless of migration policy. Restricting migration simply determines where the reserve army is located, not whether it exists. The CPB’s position amounts to demanding that British workers be protected at the expense of workers elsewhere, a nationalist betrayal dressed in Marxist vocabulary.

The Alternative Is Harder

What would it mean to reject the Fortress Left’s logic? Not rhetorical rejection, not moral condemnation, but strategic alternative?

It would mean accepting that there are no shortcuts. That rebuilding working-class organisation requires patient, unglamorous work over years and decades. That this work cannot be replaced by electoral campaigns, media appearances, or policy positioning. That the dense politics Machado describes is difficult precisely because hyperpolitical conditions militate against it, and that these conditions must be contested rather than accommodated.

It would mean organising across ethnic and national lines as a strategic priority, not an afterthought. The working class in Britain, in Germany, in the United States, is multi-ethnic, multi-national, includes migrants and their descendants as core constituents. Any politics that treats this diversity as a problem to be managed rather than a strength to be organised will fail. Mamdani won New York with a coalition that included Muslim immigrants, Black workers, Latino communities, white progressives, and anti-Zionist Jews. He did not win despite this diversity but because of it, because his campaign offered a politics capacious enough to include everyone capital exploits.

It would mean building institutions. Not just unions, though unions matter, but the whole ecosystem of working-class life: mutual aid networks, tenant organisations, community centres, political education programmes, cooperative enterprises. The Fortress Left mourns the loss of these institutions while doing nothing to rebuild them. The alternative requires actually rebuilding them, in specific places, with specific people, through specific struggles.

It would mean contesting hyperpolitical terrain without surrendering to its logic. Mamdani’s campaign shows this is possible. Viral content and door-knocking. Algorithmic reach and face-to-face conversation. Media presence and organisational depth. The synthesis is difficult but achievable. It requires saying something worth hearing and building the capacity to say it at scale.

The Road That Leads Nowhere

The balance sheet is complete. Brown’s slogan in 2007, Glasman’s project in 2011, Frederiksen’s permanent ratchet since 2019, Wagenknecht’s split in 2024, Starmer’s Act of Parliament in 2025: a lineage of capitulation, each iteration more thoroughgoing than the last, none of them achieving what they promised.

The Fortress Left does not stop the far right. The AfD is stronger now than before BSW was created. Reform UK is stronger now than before Starmer adopted restrictionist policy. The Danish People’s Party may have declined, but only because Frederiksen absorbed its programme so completely that the original was no longer needed; the ideas won, even as the party lost. In each case, the centre-left’s adoption of nativist framing legitimised the framing itself, shifted the parameters of acceptable discourse rightward, and made the next rightward lurch easier.

The Fortress Left does not build organisation. BSW had no democratic structures, no activist base, no roots in workplaces or communities. Blue Labour produced seminars, not shop stewards. Starmer’s immigration apparatus is a bureaucratic machine, not a movement. These are projects of the political class, designed to manage hyperpolitical affect from above. They cannot generate the ‘dense’ politics that alone can sustain class solidarity across ethnic and national lines, because density is precisely what they have abandoned.

The Fortress Left does not protect workers. The ten-year settlement path does not raise wages. Immigration restriction in the care sector does not fund the NHS. The fantasy that reducing migrant labour will increase native-born workers’ bargaining power evaporates on contact with the reality of a capitalist class that will automate, offshore, or simply allow services to collapse before it concedes ground to organised labour. Only organisation protects workers. The Fortress Left offers the opposite of organisation: atomised resentment, directed downward.

Against this, the controlled experiments of 2024-2026 offer a different verdict. Die Linke, which refused the nationalist turn, is rebuilding. Mamdani, who rejected the immigration-solidarity trade-off, won New York with 100,000 volunteers. Neither example guarantees anything. Politics is not physics. But both demonstrate that the Fortress Left’s core claim, that nativist accommodation is the price of relevance, is empirically false.

The alternative remains what it has always been: the slow, difficult, unglamorous work of building class organisation across every line that capital uses to divide us. It requires what Machado calls ‘dense’ politics in an era that selects for thin affect. It offers no quick wins, no media moments, no satisfying gestures of defiance against cosmopolitan elites. It requires, in short, the work that the socialist movement has always required and that each generation must undertake anew.

The Fortress Left chose the road that leads nowhere. Brandenburg in January 2026 is where that road ends: a party created to fight the far right, voting alongside it, as its ministers walk out the door. It is time to take the other path.
