UK Prime Minister Andy Burnham has suggested he is open to reversing Brexit, saying he could go "all the way" in proposing to rejoin the European Union. Speaking at the Labour Party conference in Liverpool, Burnham outlined "different options" for the UK's long-term relationship with the EU, including the possibility of resuming full membership. He also mentioned supporting the call by former Conservative Chancellor George Osborne to rejoin the EU Customs Union, a proposal Osborne made in an interview with The Independent earlier this month. Burnham claimed that Brexit had "done more harm than good," especially economically, and that it had led to a country run "for vested interests, not in the public interest." He reiterated that Britain's decision to leave the EU had "done more harm than good" and promised to present the country with options around the time of a UK-EU summit later this year. Labour's 2024 election manifesto ruled out joining a customs union, returning to the single market, or allowing the return of freedom of movement with the EU. However, Burnham has suggested he may be willing to consider options beyond those previously set as red lines. Burnham's comments follow recent opinion polls indicating that many voters believe Brexit has not worked and that a second referendum could result in a vote to rejoin the EU. The Independent has been a leading voice in advocating for Britain to rebuild its relationship with Brussels, citing evidence that Brexit has harmed the economy and failed to deliver promised benefits on issues like immigration. French President Emmanuel Macron acknowledged the hypothetical return of the UK to the EU, saying in English, "Welcome back," and expressing support for any move by the UK to rejoin. Spanish Prime Minister Pedro Sanchez echoed this sentiment, calling Brexit a "huge loss" for both the British people and the European project, and stating Spain would "applaud and open its arms again to a brotherly people" if the UK decided to return. Burnham also mentioned that the UK could remain as it is, if people believe that is the right choice, and noted that the UK could consider the Liberal Democrats' stance on the single market. He emphasized the need to evaluate the feasibility and consequences of each option. His remarks represent the furthest he has gone in suggesting a complete reversal of the historic decision to leave the EU a decade ago, potentially leading to a second referendum on the matter. Burnham's comments were quickly criticized by the Conservatives, who accused him of trying to "reopen old wounds by restarting the battles of the Brexit years." Former Conservative cabinet minister Michael Gove, who campaigned alongside former Prime Minister Boris Johnson to leave the EU, warned that reversing Brexit would "drive frustration" among the public, as it would return key policy decisions to Brussels.
