French and Spanish leaders have expressed openness to the idea of the United Kingdom rejoining the European Union, reflecting a growing debate over whether Brexit could be reversed. Roland Lescure, France’s finance minister, urged Britain to “come all the way back,” while French President Emmanuel Macron described the prospect of reversing Brexit as “excellent.” Spanish Prime Minister Pedro Sánchez added that Britain would be welcomed back with “open arms” should it seek to rejoin the bloc.
The suggestion follows renewed discussion within the UK about the political, economic, and strategic benefits of reestablishing closer ties with the EU. Andy Burnham, a prominent British politician, has been among those calling for a reassessment of the country’s post-Brexit relationship with the union. According to recent opinion polls, 59 percent of British respondents favor rejoining the EU, compared with 32 percent who oppose. However, no major UK political party has officially endorsed such a move.
Proponents argue that Brexit has adversely affected the British economy, with advisers to Prime Minister Rishi Sunak concluding that partial measures like rejoining the customs union or the single market would not fully address the challenges. A return to the EU, they suggest, could stimulate economic growth and provide greater fiscal capacity to fund public services and defense. Strategically, closer alignment with the EU is seen as critical amid transatlantic uncertainties, particularly following US President Donald Trump’s approach to Russia and questions about the future unity and effectiveness of NATO. Membership could also facilitate greater access to collective European defense initiatives.
Despite these arguments, significant obstacles remain. Any new accession process could encounter tougher conditions than those Britain had before its exit, including a possible loss of previous opt-outs such as the budget rebate, exemptions from the Schengen Area, and the eurozone. Currency and border issues continue to be sensitive topics in the UK political landscape, and any attempt to rejoin would likely face intense scrutiny. There is also skepticism toward France, regarded by some British policymakers as the most stringent EU member in negotiations with the UK. The potential election of Marine Le Pen as France’s president next year adds an element of unpredictability; her far-right policies could either complicate or, paradoxically, ease future EU-UK relations depending on broader shifts within the union.
The EU itself faces a choice about whether it wants the UK back as a member. While a British return could boost the bloc’s economic and military capabilities, reassure international partners, and serve as a vote of confidence in the European project, it would also require significant diplomatic effort and time to negotiate the terms. Brussels would likely seek assurance of a stable, long-term political consensus in the UK before engaging in re-entry talks, to avoid future disruptions similar to those experienced during and after Brexit.
Ultimately, whether Britain can rejoin the EU depends on shared strategic interests on both sides and the willingness to navigate complex practical and political realities. If a clear mutual benefit is identified, re-accession remains a possibility, though a challenging one.
