BRUSSELS, 11 October, (Brussels Morning Newspaper) – A new UK EU rejoining report has revealed that Britain could potentially return to the European Union within a single parliamentary term, challenging assumptions that reversing Brexit would require a decade of negotiations.
The findings, published by pro-European campaign organisation Best for Britain, suggest that Britain’s previous membership, existing regulatory alignment and established institutional relationships could significantly shorten the accession process.
The assessment comes amid renewed debate over Britain’s European future, as Prime Minister Andy Burnham considers closer cooperation with Brussels and potential changes to the country’s post-Brexit relationship.
New Research Reveals Potential Fast-Track EU Membership
The study, titled How the UK joins the EU, and how long it would take, examines the legal and political procedures required for Britain to regain membership.
Researchers highlight Finland’s accession as an important historical comparison.
Finland applied for EU membership in March 1992 and formally joined in January 1995. Its accession negotiations lasted approximately 13 months.
Best for Britain argues that Britain’s existing familiarity with European legislation and institutions could provide advantages unavailable to first-time applicants.
However, the organisation acknowledges that accession would depend on political agreement between London and the EU’s existing member states.
European Officials Address Britain’s Possible Return
The UK EU rejoining report has attracted attention from European political figures involved in relations with Britain.
Sandro Gozi, a Member of the European Parliament and chair of the European Parliament’s delegation to the UK-EU Parliamentary Partnership Assembly, welcomed the possibility of a shorter accession timetable.
He said:
“As a former member, and with much of the regulatory framework already in place, I personally do not see any serious reason why an application from the UK would not be achievable within one parliament.”
Former European Commission director-general Sir Jonathan Faull also recognised Britain’s distinctive position as a former member.
However, he stressed that any accession process would still require detailed negotiations and unanimous agreement among member states.
Brexit History Shapes Renewed EU Membership Debate
Britain voted to leave the European Union in June 2016 and formally withdrew on 31 January 2020.
The transition period ended in December 2020, removing Britain from the EU’s single market and customs union.
Since then, businesses have faced changes to customs procedures, regulatory requirements and cross-border trading arrangements.
The latest research argues that Britain’s limited divergence from certain EU regulations could make renewed integration less complicated than previously suggested.
Separate polling commissioned by Best for Britain and conducted by YouGov between May and June 2026 surveyed 11,927 respondents, finding substantial support for renewed membership among Labour, Liberal Democrat and Green supporters.
Economic and Political Implications for Brussels
The proposed accession timetable raises significant questions for European policymakers, businesses and British citizens.
Renewed membership would affect trade arrangements, investment, labour mobility and Britain’s participation in EU decision-making.
Nevertheless, important issues would require negotiation, including financial contributions, fisheries, immigration arrangements and obligations associated with EU membership.
The UK would also need to demonstrate compliance with the bloc’s accession requirements.
Under Article 49 of the Treaty on European Union, membership requires approval from existing EU countries and completion of the relevant ratification procedures.
What Happens Next for Britain and the EU?
The UK EU rejoining report does not represent a formal British application or an agreement with Brussels.
The next significant development will depend on whether the British Government adopts EU membership as an official policy objective.
London and Brussels are also preparing for further discussions on their post-Brexit relationship, including trade barriers, emissions trading and youth mobility arrangements.
For now, the findings provide a new assessment of how quickly Britain could return, while leaving the ultimate decision with British political leaders and the European Union’s member states.
