British Prime Minister Andy Burnham has reopened the debate over the United Kingdom’s long-term relationship with the European Union, saying that several possible arrangements should be examined, including the possibility of eventually rejoining the bloc.

Speaking during the Labour Party’s annual conference and in subsequent interviews on September 30, Burnham said Britain should assess what future relationship with Europe would be practical and beneficial. He said the government would set out different options around a planned UK-EU summit later this year.

Several Options Under Consideration

Burnham said the UK could maintain its current post-Brexit arrangement, pursue a customs union with the EU, seek closer participation in the European single market or consider going further and ultimately rejoining the European Union.

He stressed that the options should be examined on the basis of what is achievable and by considering their advantages and disadvantages.

The comments represent a significant reopening of a debate that has remained politically sensitive since the 2016 Brexit referendum.

Burnham Criticises the Current Brexit Settlement

During his Labour conference speech, Burnham said Brexit had “done more harm than good” and argued that Britain needed greater clarity about its long-term relationship with its European neighbours.

He said the government could not leave the question unresolved indefinitely and planned to use the forthcoming UK-EU summit to present possible approaches.

The prime minister has previously indicated that he would like Britain to eventually return to the EU, although the government has not announced an immediate policy to begin the process of rejoining.

Possible Return to the Single Market or Customs Union

One option discussed by Burnham is closer economic integration without immediately restoring full EU membership.

A customs union could reduce some trade barriers between Britain and the EU, while participation in the single market would provide a much closer economic relationship.

Full EU membership would be a substantially larger change because it would involve negotiations with the European Union and would require Britain to meet the bloc’s membership requirements.

Political Debate Intensifies

Burnham’s comments have already drawn criticism from political opponents who argue that the government should respect the outcome of the 2016 referendum and avoid reopening the Brexit question.

Supporters of closer European ties, meanwhile, have argued that Britain should examine whether changes to its relationship with the EU could improve trade and economic cooperation.

The issue is therefore likely to remain politically contested as the government develops its proposals.

UK-EU Summit Expected Later This Year

Burnham has said he intends to present the different possibilities around the next UK-EU summit, which is expected to take place later in 2026.

The discussion could include Britain’s existing trade relationship with the EU as well as broader cooperation in areas such as economic policy and regulatory arrangements.

For now, no decision has been announced to begin formal negotiations for Britain to rejoin the European Union. The government’s stated position is that the possible long-term options need to be assessed before a future course is chosen.

Brexit Debate Enters a New Phase

The latest statements from Downing Street have placed Britain’s relationship with Europe back at the centre of national political discussion.

The immediate focus will be on the options Burnham’s government presents at the forthcoming summit and how those proposals could shape Britain’s relationship with the EU in the years ahead.
