Britain rejoin EU debate

Highlights

Opinion polling shows 59 per cent of Britons support rejoining the EU, creating political opportunities for parties like Labour amid economic headwinds from Brexit.
Advisers to the prime minister conclude that full EU membership could offer the strongest boost to UK growth and public spending, beyond customs union or single market options.
European leaders remain cautious, requiring lasting UK consensus and warning that a Marine Le Pen presidency or Brexit-era UK opt-outs could complicate re-entry negotiations.

Political support and barriers to re-entry

As reported by Financial Times, comments from European leaders and UK political figures are adding momentum to a debate that no major British party has yet formally embraced. France's finance minister Roland Lescure says Britain should come "all the way back" after Greater Manchester mayor Andy Burnham suggests the UK needs to rethink its relationship with the EU, while French President Emmanuel Macron and Spanish Prime Minister Pedro Sánchez also signal support for a return.

The political case rests in part on opinion polling that suggests 59 per cent of British people want to rejoin the EU, with 32 per cent opposed. The article argues that this leaves a gap in party politics, with Labour potentially able to benefit if it adopted a clearer pro-EU stance.

Economic considerations are also central to the argument. Advisers to the prime minister have concluded that Brexit is acting as a drag on the British economy, and that rejoining only the customs union or the EU single market would not fully repair the damage, making full EU membership a more consequential option for growth and public spending capacity.

Any re-entry process would still be difficult. The UK could not assume it would regain its previous budget rebate or keep opt-outs from Schengen and the euro, both of which remain politically sensitive issues in Britain.

Strategic case strengthens as Europe faces new risks

The strategic argument for closer integration with Europe is strengthening as doubts grow over transatlantic security arrangements. Differences between the U.S. and Britain over Ukraine, alongside weakening confidence in Nato's future, are presented as reasons why the UK may find deeper cooperation with European allies more necessary, particularly in defence spending.

The article also says the EU would need convincing that British support for rejoining is durable. European governments are likely to want evidence of a settled domestic consensus before investing political capital in a re-entry treaty that could later be overturned by a future UK government.

French politics adds further uncertainty. A possible victory for Marine Le Pen in next year's presidential election could reshape the terms of any future British application, either by making the EU less attractive to the UK or by loosening the bloc's integrationist direction in ways that could make British re-entry easier.

For the EU, a British return could still offer clear benefits. The bloc would gain added economic scale, military weight and a significant budget contributor at a time when the European project is under pressure from a more hostile international environment.

Our earlier coverage of the UK-EU post-Brexit reset talks explained how London and Brussels were entering a crunch negotiating phase ahead of a November summit, with discussions spanning border checks, linking carbon markets and a youth mobility scheme. It also highlighted Andy Burnham’s push to reopen the debate on closer ties with Europe, arguing a fresh deal could support growth while disputes such as tuition fees and the scale of mobility arrangements remained key hurdles.
