Renewed Debate on UK-EU Reunification
Wes Streeting, who resigned as Britain's health secretary and is a contender for the Labour leadership, has labeled Brexit a "catastrophic mistake" and advocated for the UK to rejoin the European Union. Andy Burnham, the Labour mayor of Greater Manchester, also sees a "long-term case" for rejoining, though not immediately. These statements from potential future prime ministers have reignited debate over the UK-EU relationship.
Current State of UK-EU Relations
Since his 2024 election, Prime Minister Keir Starmer promised a "reset" with the EU, aiming to end years of friction and secure new economic deals. A year later, he touted a summit agreement providing "unprecedented access to the EU market." However, concrete progress remains limited. The UK rejoined the Horizon science program and will rejoin Erasmus+ from 2027, but talks on youth mobility, electricity market integration, and defense procurement have stalled due to disagreements over fees and financial contributions.
Obstacles to Closer Ties
Starmer's government maintains red lines: no return to the customs union, single market, or freedom of movement. The EU insists that closer ties require alignment with its rules. Any moves toward alignment are criticized by Reform UK and Conservatives as "undoing Brexit by the back door." Economists estimate Brexit has reduced UK economic output by 6-8%, and sectoral mini-deals are unlikely to reverse this significantly. Starmer acknowledged that "incremental change won't cut it," but a bigger response would require easing those red lines.
How Would the EU Welcome a Rejoin Bid?
The geopolitical landscape has shifted since 2016: Russia's war in Ukraine, a shaken US-UK special relationship, and threats to the rules-based order. Analysts argue both sides would benefit from a fundamental relationship rethink. A YouGov poll shows 63% of Britons want closer EU ties, and 55% support rejoining. EU nations also show majority support for UK return, but they would expect standard membership terms, including joining the euro and forgoing previous opt-outs. EU leaders may also demand clauses to prevent a future UK government from reversing any deal. Given today's realities, any UK rejoin bid would be seriously considered.
