UK would be blocked from rejoining 'wounded' EU, says Jean-Claude Juncker

Jean-Claude Juncker has said the UK would face political resistance if it ever tried to rejoin the European Union, arguing that member states remain “wounded” by Brexit and would not be inclined to offer Britain the special terms it once enjoyed.

The former European Commission president made the comments in an interview with the Financial Times published on June 15, 2026, as debate in the UK about the long-term possibility of returning to the bloc has gathered fresh attention around the 10th anniversary of the 2016 referendum.

Juncker said he did not believe a re-entry bid would be easy to advance under current political conditions. He said a majority of European governments would likely cold-shoulder such an application and that the UK would not automatically recover its former opt-outs on the euro, Schengen or some budget contributions.

Brexit’s long shadow

The UK voted to leave the EU in 2016 and formally exited on January 31, 2020. Since then, British politics has repeatedly returned to the question of whether Brexit could one day be reversed, even if no formal rejoining process is under way.

Recent commentary in Brussels has suggested that, if the UK ever sought to return, it would be expected to follow normal accession rules rather than receive a tailor-made deal. That would mean accepting standard membership terms and persuading all EU governments to agree.

Juncker’s remarks fit that broader view. He portrayed the bloc as still bruised by the breakup and skeptical of giving the UK the same exceptions it had negotiated as a member.

What a return would require

Any future British bid to rejoin would still face the basic legal and political hurdles of EU enlargement: unanimous support from member states and agreement on the conditions of accession.

The comments do not amount to a formal EU decision, but they underline the depth of resistance that could confront any renewed push from London. For now, the story remains political rather than procedural, with the latest debate centered on whether a future UK government would even choose to pursue re-entry.

The Financial Times report comes as pro-rejoin arguments continue to surface in UK politics, including among some figures who see eventual EU return as possible. But Juncker’s warning suggests that even if the debate gains momentum in Britain, the reception in Brussels would be far from welcoming.
