Burnham Opens Door to EU Rejoin Debate as Brexit Reset Becomes Labour's Next Battleground

Andy Burnham has signalled that rejoining the European Union could form part of a broader review of Britain's relationship with Brussels, in comments that threaten to reignite one of the most divisive arguments in recent British politics.

In an interview with BBC Radio 4's Today programme, the prime minister said the existing Brexit arrangements had delivered "more harm than good" and indicated he wanted to explore what might realistically be achieved to improve ties with the bloc.

Asked directly whether he favoured the UK returning to the EU, Burnham stopped short of an explicit endorsement. Instead, he said he wanted to "look at the options" and set out a range of possible paths, from maintaining the status quo through to full membership.

The intervention follows his keynote address to the Labour conference on Tuesday, in which he committed to examining closer cooperation with the EU at a summit that has been pushed back to later this year. He also used that speech to promise a ten-year plan aimed at overhauling the British economy.

Burnham's latest remarks represent his clearest signal yet that he may be willing to depart from the manifesto on which Labour fought the 2024 general election. That document pledged to "make Brexit work" while explicitly ruling out joining either the EU's customs union or its single market. The manifesto's departure has also been delayed by the leadership transition that followed his return to front-line politics.

The prime minister framed the question as one that should not be left unresolved. He said he did not want the issue to remain "hanging" and stressed the need for clarity about "where we want Britain to go in the next decade." He also noted he had previously supported rejoining within his own lifetime, while conceding that circumstances may have changed.

Setting out the menu of choices, Burnham referenced proposals floated by former chancellor George Osborne for a customs union arrangement, and the Liberal Democrats' conference position favouring single market membership. He also left open the possibility of going "all the way," a phrase widely interpreted as meaning full EU membership.

"We could stay as we are," he told the programme, describing the current settlement as a legitimate option for those who believe it is the right place for Britain to remain. He added that any path forward would need to weigh the advantages and disadvantages of each alternative and be tested against what is deliverable.

The political sensitivity of the subject is considerable. Burnham campaigned in the Makerfield by-election on a promise not to "re-run" the arguments of the Brexit years, and at that time said he was not proposing that the UK consider rejoining. His comments now sit awkwardly alongside that commitment and are likely to be seized upon by opponents.

The Conservatives moved quickly to attack the position. Deputy leader Alex Burghart accused Labour of trying to blame a vote held more than a decade ago for its own economic decisions, and claimed the government was already pulling Britain towards the EU "by the back door" through its existing reset agenda.

The government's current approach has been more modest than full membership. Under Burnham's predecessor, Sir Keir Starmer, the emphasis was placed on a limited reset encompassing alignment with EU food standards, a youth mobility visa scheme, and reconnecting British industry to the EU's carbon trading regime. That approach was designed to reduce friction without reopening the fundamental question of membership.

The summer summit at which Burnham intends to present his options was postponed because of the change of leader, and is now expected to take place later in the year. The prime minister has said he wants to use that gathering to lay out "different options" for the long-term relationship and to "find consensus" around a preferred direction, though he has not explained how that consensus would be measured or tested.

The timing ensures the issue will feature prominently at the next general election. Rejoining the EU, or even moving towards a customs union, would represent a decisive break from the position Labour took to the country in 2024 and would hand the Conservatives a ready-made line of attack centred on reopening old divisions.

For businesses, the debate matters because the current arrangements continue to generate friction at the border, added costs, and uncertainty in sectors ranging from food and farming to manufacturing and professional services. For voters, it raises questions about immigration, sovereignty, and economic growth that cut across traditional party lines.

Burnham's allies argue that a frank assessment of the options is more honest than pretending the status quo is settled. Critics counter that raising expectations of a rejoin dividend without a clear route to delivering it risks destabilising the government's economic message and distracting from domestic priorities.

What is not yet clear is whether the prime minister intends to seek a mandate for any particular option, or whether the exercise is designed chiefly to frame a longer-term debate. His conference speech promised to "find consensus," a formulation elastic enough to accommodate anything from minor tweaks to a historic reversal.

For now, the immediate consequence is that Brexit has returned to the centre of British political argument. A question that many in Westminster had consigned to the past is once again live, and the next election may well turn on how far either party is prepared to go.
