Andy Burnham has done something no British prime minister has done since 2016: he told the country, plainly, that Brexit failed. Speaking at Labour's annual conference, Burnham declared that leaving the EU had done 'more harm than good' and announced a six-week public consultation on the UK's future relationship with Europe — with full rejoin explicitly on the table. This is not a reset. This is the beginning of a reversal debate. The move dismantles the red lines Keir Starmer embedded in Labour's 2024 manifesto: no single market, no customs union, no free movement. Those constraints left Starmer negotiating from weakness, producing a 'reset' agenda now bogged down in disputes over EU student fees and a summit on 20 November still unconfirmed. The government's own projections show Starmer's approach would add at most 0.3% to GDP by 2040. Against estimated Brexit damage of 6-8% of GDP, that arithmetic speaks for itself. Burnham's political calculus is multi-layered. Labour has bled votes to the Greens on its left flank. New polling shows almost half the country supports rejoining the EU outright. The Conservatives, fixated on growth, may find it awkward to align with Nigel Farage — the only prominent figure to react with 'unfettered glee' — when most voters believe Brexit has made them economically worse off. The political risk of the conversation has quietly shifted. But Europe is not standing still. France's 'Made in Europe' initiative — a protectionist industrial strategy designed to counter Chinese competition — threatens to legally classify UK-made goods as non-European, potentially devastating the British car industry. The EU's competencies have expanded dramatically since Brexit into industrial policy, AI regulation, and tech sovereignty. Every month outside the club, the re-entry price rises. The strategic logic is stark. As EU nations pool sovereignty to counter US antagonism and Russian hybrid warfare, and as 'Made in Europe' protections harden, the costs of non-membership compound. Norway and Switzerland, both non-EU members with single market access, already face Made in Europe exclusion. The full rejoin option exists not because of nostalgia but because the halfway houses are collapsing. Burnham is not yet committed to a specific position for the next election. The six-week consultation is designed to gauge appetite before locking in. But as analyst Joël Reland of UK In a Changing Europe noted, 'I don't see why you would do that unless you wanted to take on the political argument.' The deliberate opening of a door that Starmer welded shut is itself the signal. The harder question — raised by Mujtaba Rahman — is whether the British public is ready for an honest conversation about what the EU has become since 2016. Rejoining would mean accepting an institution with far broader powers than the one Britain left: an EU that sets industrial strategy, regulates AI, and makes hard security decisions collectively. The debate ahead is not just about whether Britain goes back, but what it would be going back to.
