A decade after the referendum, the polling trendlines on Brexit have shifted dramatically enough to tempt political entrepreneurs. A megapoll of 11,000 people found 50% support rejoining the EU, with only 28% opposed. A More in Common constituency-level analysis found that just 11 of Britain's 632 constituencies would vote leave today — including a 52% rejoin majority in Nigel Farage's Clacton. The demographic engine behind the shift is structural: older leave voters are dying, younger voters skew heavily pro-EU, and a slice of 2016 leavers have switched after a decade of buyer's remorse. Andy Burnham, positioning himself ahead of a general election, has broken what the Guardian calls an omertà among Labour politicians. At party conference he called the status quo inadequate and put full EU membership back on the table. The political logic is clear: Labour's electoral coalition is roughly 80% remain and growing. The parties competing for Labour's left flank — Greens, Liberal Democrats — are even more pro-EU. Meanwhile, the Conservative party has shed its hardline Brexiters to Reform, leaving it internally divided on the issue. Burnham can potentially do more damage to the right than to his own base. But polling support and referendum resilience are not the same thing. Luke Tryl of More in Common warns that rejoin would start ahead in any future campaign but that headline numbers would erode under sustained opposition messaging. Rob Ford, professor of political science at Manchester, notes the EU itself would resist serious negotiations while a future Reform government could reverse any deal. The lesson of 2016 — that comfortable polling leads evaporate in actual campaigns — has not been forgotten by anyone paying attention. The economic case for closer alignment is becoming harder to ignore. The EU's protectionist 'Made in Europe' legislation threatens British manufacturing access, and the prime minister has publicly acknowledged the risk. Constituents in formerly leave-voting areas like Hull East (74% leave in 2016) are reporting higher costs and fewer opportunities. Karl Turner, the constituency's MP, says his voters are 'increasingly ready to consider the practical benefits of rejoining.' The deeper risk Ford identifies is not that the conversation is wrong but that it becomes all-consuming. During the Brexit years, it proved impossible to sustain public attention on any other structural issue — housing, healthcare, industrial strategy. If Burnham's gambit takes on a life of its own, the very problems that make closer EU alignment attractive could be crowded out of political discourse. Brexit as catnip, drawing all oxygen from the room. What's notable about this moment is the asymmetry between polling clarity and institutional readiness. The public has moved substantially, but the political infrastructure for acting on that shift barely exists. No treaty framework, no negotiating mandate, no cross-party consensus on terms. The gap between 'most people think leaving was a mistake' and 'the country is ready to rejoin' contains years of diplomatic, legal, and political work that no one has begun. Burnham's move is rational as electoral positioning — the numbers support it. Whether it generates real value or simply reopens a decade-old extraction cycle depends entirely on whether political leaders can hold the conversation to concrete trade and regulatory questions rather than letting it collapse back into identity warfare.
