The debate over the United Kingdom’s relationship with the European Union has returned to the forefront of British politics. This shift follows declarations from two prominent Labour figures currently positioning themselves for the party’s leadership.
Wes Streeting, who resigned as health secretary last week, has described Brexit as a “catastrophic mistake” and stated that the UK should rejoin the EU. Similarly, Andy Burnham, the Labour mayor of Greater Manchester, has noted a “long-term case” for rejoining, though he indicated he would not advocate for this move immediately.
The Current State of UK-EU Relations
Since his election in 2024, Prime Minister Keir Starmer has pursued a “reset” of ties with the 27-member bloc. He has aimed to move past years of fractious relations to secure new economic deals with the UK’s largest trading partner.
Following a summit in London, Starmer claimed a wide-ranging agreement provides “unprecedented access to the EU market, the best of any country,” which he suggested would lead to “cheaper food and energy” for citizens.
However, concrete progress has remained limited. While the UK has rejoined the EU’s Horizon science programme and is set to rejoin the Erasmus+ programme for educational and training exchanges from 2027 for at least one year, other negotiations are stalled.
Disagreements over tuition fees for EU students have hindered a “youth mobility scheme,” while London’s refusal to pay into EU “cohesion funds” has blocked integration into Europe’s electricity market. A deal to join the SAFE defence procurement fund failed due to financial contributions demanded by Brussels.
Obstacles to Closer Integration
The primary barriers to significant improvement are the “red lines” established by the Starmer government: no return to the single market, no return to the customs union, and no return to freedom of movement.
The European Union maintains that closer ties require the UK to align more strictly with EU rules and regulations. This alignment has been criticized by the Conservatives and Reform UK as “undoing Brexit by the back door.”
Starmer has acknowledged that “incremental change won’t cut it” and that a “bigger response” is needed. However, any agreement that would make a significant economic difference, such as joining the single market, would require allowing EU citizens the freedom to live and work in the UK.
The Prospect of Rejoining
The geopolitical landscape of 2026 differs sharply from 2016, characterized by Russia’s war in Ukraine and a shaken “special relationship” between the UK and the US. Analysts suggest both the EU and UK could benefit from a rethink of their relationship to enhance security and prosperity.
Public sentiment appears to have shifted; a recent YouGov poll indicated 63% of Britons want a closer relationship with the EU, and 55% want to rejoin. Support for a UK return is at or above 50% in Italy, Spain, France, and Germany.
However, the EU would likely impose strict terms. Poland’s foreign minister, Radosław Sikorski, stated that Britain would not receive its previous rebate or opt-outs. He emphasized that closer ties require “pooling some aspects of sovereignty” and “honouring rules you didn’t make yourself.”
the EU may insist on the UK joining the euro. To protect against a future government undoing such a deal, European leaders could demand penalty clauses.
What May Happen Next
If a leadership contest occurs, the UK-EU relationship may become a central campaign issue. A new leader could potentially ease the existing “red lines” to pursue more far-reaching economic agreements.
In the short term, the government may attempt to seal deals on carbon emissions trading, food and agricultural products, and the “youth experience” scheme by the next UK-EU summit this summer.
any formal bid to rejoin would likely be seriously entertained by the EU due to current geostrategic realities, provided the UK accepts the terms of new membership.
