Blair Institute urges UK to pursue EU re-entry within decade, contingent on Brussels reforms

Key points

• The Tony Blair Institute released a paper titled 'A Path to Rejoining a Reformed Europe,' arguing that the UK should signal intent to rejoin the EU if Brussels commits to significant structural reforms.
• The report proposes that the UK accept free movement of people and make financial contributions as conditions for re-entry, while using the prospect of membership to push for liberalized EU regulations on energy and technology.
• Prime Minister Andy Burnham has stated he hopes to see the UK rejoin the EU in his lifetime but has refused to rule out or confirm the issue for the next Labour manifesto, calling it a question 'for another day.'
• A YouGov megapoll commissioned by the pro-EU group Best for Britain suggests that a pledge to rejoin could double Labour’s seat count from 136 to 321, though this data predates Burnham’s recent poll lead.
• The Tony Blair Institute has faced scrutiny for its policy positions on net zero and artificial intelligence, with critics noting its funding from technology billionaire Larry Ellison and client relationships with the Saudi Arabian government.

Background

This debate follows the 2016 referendum and subsequent Brexit, which remains a polarizing issue in UK politics. Recent events, such as Iceland’s narrow rejection of resuming EU talks in September 2026, have highlighted the complexities of EU accession processes and the sensitivity of sovereignty issues among voters. Additionally, the EU’s recent diplomatic efforts to engage with non-member states like Canada suggest a broader strategic shift in Brussels regarding external partnerships, which may influence the terms of any future UK-EU negotiations.

How outlets are covering it

The Guardian and Politico emphasize the political pressure on Prime Minister Andy Burnham to address EU re-entry in his upcoming 10-year plan, noting that while he has expressed personal support, he is cautious about electoral consequences. The Independent’s headline suggests that the primary obstacle to rejoining may be the EU itself, implying that Brussels’s willingness to reform is the critical variable. In contrast, internal Labour figures like Culture Secretary Lisa Nandy have dismissed the idea, warning against reopening divisive arguments. Pollsters cited by The Guardian argue that a pro-EU stance could significantly boost Labour’s electoral prospects, while skeptics fear it could alienate voters in constituencies where Reform UK has made inroads. The Telegraph was inaccessible due to a security block, so its perspective could not be analyzed.

Why it matters

The potential return to the EU would fundamentally reshape UK trade, immigration, and regulatory frameworks, reversing a decade of post-Brexit policy. It would also signal a major shift in UK foreign policy, potentially realigning the country with European strategic and economic interests. For the Labour Party, the decision carries significant electoral risk and reward, as it could either unify progressive voters or alienate those who voted for Brexit. The outcome will also influence the EU’s own reform agenda, as the UK’s leverage could push for changes in energy, technology, and market regulations that affect all member states.

What to watch

Prime Minister Andy Burnham is expected to present his 10-year plan in November, which may include a formal stance on EU re-entry. The Tony Blair Institute will likely continue to advocate for its proposals, while Labour MPs will debate the electoral wisdom of committing to re-entry in the next manifesto. The EU’s response to the UK’s potential overtures will be crucial, as Brussels must decide whether to engage with the UK’s reform demands or maintain its current position. Polling data will also be updated to reflect any shifts in public opinion following Burnham’s announcement.
