UK Re-joining the EU: New Reports Outline Fast-Track Possibility and Decade-Long Roadmap
By Drooid · · How we work
Core Findings – A One-Parliament Term Timeline
A report released on October 11 by the pro-European campaign group Best for Britain argues that the United Kingdom could regain EU membership within a single parliamentary term. The analysis, titled *How the UK joins the EU, and how long it would take*, points to the United Kingdom’s existing regulatory alignment and institutional familiarity as factors that could compress the accession process. The study cites Finland’s 13-month accession (application March 1992, membership January 1995) as a historical parallel, suggesting a “fast-track” advantage unavailable to first-time applicants.
Background & Context
The United Kingdom voted to leave the European Union in June 2016 and formally exited on 31 January 2020. The transition period ended in December 2020, removing the UK from the single market and customs union. Prime Minister Andy Burnham has signaled openness to revisiting the post-Brexit relationship, prompting renewed discussion of full EU membership.
Data & Statistics
- A YouGov poll commissioned by Best for Britain between May and June 2026 surveyed 11,927 respondents and found strong support for renewed membership among Labour, Liberal Democrat and Green voters.
- A poll by European Movement UK with Observant reported that 57 % would vote to re-join the EU in a referendum, compared with 30 % opposed.
- The European Movement estimates that trade barriers imposed since Brexit have left the UK 4 % to 8 % poorer than it would have been without them.
- The think-tank notes that the shortest recent accession periods—Finland and Sweden—took about three years, owing to their prior alignment with EU law as EFTA members.
Official Statements & Responses
- Former European Commission director-general Sir Jonathan Faull acknowledged the UK’s distinctive position but emphasized that accession would still require detailed negotiations and unanimous approval from all member states.
- Lord Neil Kinnock argued that a decade to regain full admission is “sensible” but could be shortened by economic and security pressures.
- Andy Burnham declared that Brexit “has not worked” and characterized the past ten years as a “decade of drift and division.” He announced a parliamentary debate on a petition supporting re-entry, which has generated roughly 26,000 letters to MPs.
Conflicting Reports & Gaps
The Best for Britain analysis projects accession within a single parliamentary term, whereas the European Movement roadmap envisions a ten-year horizon, targeting 2036 or earlier. Both agree that political consensus in London and unanimous approval in Brussels are prerequisites, but they differ on the expected speed of negotiations. No formal application has been lodged, and the timeline for any referendum or ratification process remains undefined.

What’s Next
The next decisive step hinges on whether the British government adopts EU membership as an official policy objective. A manifesto commitment in the upcoming election—expected in 2029—could provide the electoral mandate required to launch a formal application. Should the UK pursue accession, Article 49 of the Treaty on European Union mandates approval by all existing member states and subsequent ratification procedures, potentially including a second referendum. Negotiations would need to address financial contributions, fisheries, immigration and other accession criteria, with any single member state capable of halting progress until consensus is reached.
