UK Prime Minister Opens Door to EU Rejoining, Signaling Major Shift on Brexit

Burnham Signals Openness to Full EU Rejoining

The UK's prime minister has indicated that rejoining the European Union could be among several options the government examines as it reconsiders Britain's long-term relationship with the bloc. In remarks to BBC Radio 4, Burnham stated he wanted to "look at the options" regarding EU ties, explicitly mentioning the possibility of going "all the way" back into full membership. This represents a significant evolution from Labour's 2024 election manifesto, which pledged to make Brexit work while explicitly ruling out rejoining the customs union or single market. Burnham's comments come after he devoted substantial portions of his conference speech to criticizing the current Brexit settlement, arguing it has caused "more harm than good" and failed to deliver the promised controls over immigration and economic management.

A Break from Previous Positioning

Burnham's latest statements mark a considerable departure from commitments he made as a candidate in a recent by-election, when he pledged not to "re-run" Brexit arguments and said he was "not proposing that the UK considers rejoining the EU." His predecessor, Sir Keir Starmer, had pursued a more limited approach, pursuing incremental improvements like aligning food standards with the EU, establishing a youth mobility visa scheme, and reconnecting British industry to the EU's carbon trading system. Burnham has now suggested a spectrum of possibilities: maintaining the status quo, pursuing a customs union arrangement (as previously proposed by former Chancellor George Osborne), adopting single market membership (as advocated by the Liberal Democrats), or proceeding to full EU membership. He emphasized the need to evaluate what is practically achievable and weigh the advantages and disadvantages of each pathway.

Political Fallout and Opposition

The shift has already provoked sharp reactions from political opponents. The Conservative Party's deputy leader characterized the government as attempting to drag Britain "into the European Union via the back door" and accused Labour of scapegoating a referendum that occurred over a decade ago. Reform UK's deputy leader Richard Tice claimed Burnham was trying to "sneak us back into Brussels" and argued that real harm has come from Labour's inability to deliver economic growth and control migration. The Green Party leader acknowledged that Brexit has weakened the UK economy but criticized Burnham for merely keeping options open rather than committing to customs union membership. Liberal Democrat leader Sir Ed Davey called for concrete action rather than continued deliberation, pushing Burnham to begin negotiations for a better deal immediately.

EU Perspective and Practical Challenges

The European Union has signaled receptiveness to deeper UK engagement. The EU's ambassador to the UK noted that the bloc's doors remain open but emphasized that Britain must articulate its ambitions. However, practical obstacles exist to full rejoining. The Liberal Democrats' Europe spokesperson cautioned that Britain would likely be treated as a "fresh entrant state" under existing EU procedures and would need to demonstrate to European partners that re-engagement serves their interests as well. Public consent would be critical, with experts suggesting the British public must support any shift in a "sustainable way." Burnham plans to publish a comprehensive 10-year economic transformation plan at a delayed EU summit scheduled for later in the year, where he intends to outline the government's preferred direction on European relations.

Electoral Implications

Analysts anticipate this could become a defining issue at the next general election, creating a sharp dividing line between Labour and the Conservatives. The timing of Burnham's remarks—less than a year after Labour won office on a platform of making the existing Brexit arrangement functional—suggests he is willing to stake significant political capital on reopening the European question. The move also positions Labour to the left of its previous stance, potentially appealing to voters who view Brexit as economically damaging while simultaneously exposing the government to accusations of flip-flopping on a settled issue.
