Tony Blair Urges Britain to Target EU Re-Entry Within a Decade

By Drooid · · How we work

Core Event

Former prime minister Sir Tony Blair released a foreword to the Tony Blair Institute (TBI) paper *Beyond Leave and Remain: A Path to Rejoining a Reformed Europe* on September 24.

Background & Context

The 2016 referendum left the UK outside the EU, a decision that remains central to political debate. Labour’s 2024 manifesto introduced “Brexit red lines” that barred re-entry to the single market, customs union, and free-movement of people. Polling commissioned by Best for Britain now shows a majority of voters regret the 2016 vote and favour a return to full membership.

Data & Statistics

  • Constituency support: YouGov analysis for Best for Britain found EU membership the preferred option in 628 of 632 UK constituencies.
  • National preference: 35 % of respondents favoured EU membership versus 18 % for the current “closer-relations” approach. Earlier polling recorded 53 % support for re-joining versus 32 % opposition.
  • Electoral impact: A YouGov megasurvey of over 13,000 adults projected Labour’s seat total could rise from 136 to 321 if a re-join pledge were included in the next election manifesto.
  • Economic loss estimates: The Institute for Public Policy Research (IPPR) calculated a loss of £6.5 bn a year in exports without a mutual-recognition agreement; Logistics UK reported an overall export loss of £11.7 bn annually. The Office for Budget Responsibility (OBR) estimates the current UK-EU settlement reduces long-term productivity by about 4 %.

Official Statements & Responses

  • Andy Burnham described the EU re-join question as “for another day” and said his priority is to rebuild relations without committing to immediate membership.
  • Conservative MP Mike Wood criticised the Blair paper as a “betrayal” and warned Labour of “turning back the clock.”
  • Liberal Democrat Europe spokesman Al Pinkerton welcomed the report, stating a new partnership is needed to meet today’s economic and security challenges.

Criticism & Opposition

  • The Conservative Party argues that abandoning the 2024 manifesto red lines would alienate voters who supported Brexit and could empower opposition parties.
  • Reform UK warns a re-join pledge could reopen the “deep rifts” created by the 2016 vote.

Verbatim Quotes

  • “This objective should be a cornerstone of the UK government’s upcoming 10-year plan.” — Sir Tony Blair
  • “Europe's biggest problem isn't a lack of institutions but a lack of delivery. Britain should help turn the European Political Community from a forum for dialogue into a working one for power, pulling together willing countries to get things built and done.” — Tone Langengen, TBI Director
  • “Everything points to there being little scope to further deepen UK-EU relations without revisiting the UK Government’s red lines. Only full EU membership can grow the UK economy by at least £92bn per year, and it is supported by a majority of the electorate, particularly Labour’s coalition of voters.” — Naomi Smith, Best for Britain chief executive

What’s Next

  • A parliamentary debate on re-joining the EU is scheduled for 12 October.
  • Labour’s annual conference opens in Liverpool on 27 September, where the party’s stance on EU relations will be discussed.
  • The government’s 10-year plan, due in November, will indicate whether the Blair-sponsored objective is adopted.
