British Prime Minister Andy Burnham has signaled a renewed willingness to reconsider the United Kingdom’s relationship with the European Union, marking a significant shift in the post-Brexit political landscape nearly a decade after the 2016 referendum that led to the UK’s withdrawal from the bloc.
In late September, on the sidelines of the United Nations General Assembly in New York, Burnham privately indicated to European Commission President Ursula von der Leyen that the UK is open to exploring closer ties with the EU, including the possibility of rejoining the union. This marked a departure from the entrenched positions that have prevailed in British politics since the departure, with Burnham asserting that public opinion in the UK favors re-engagement more than Westminster’s political elite.
At the Labour Party conference held shortly afterward in Liverpool, Burnham publicly proposed revisiting Britain’s “long-term relationship” with the EU, including membership in the Customs Union and the single market. French President Emmanuel Macron welcomed the overture, though he stressed that rejoining the EU would require full acceptance of its fundamental freedoms and obligations without selective participation. Spanish Prime Minister Pedro Sanchez also expressed support for Britain's potential return.
Despite the warm reception from some EU leaders, significant challenges remain. Macron’s remarks underscored the EU’s position that any renewed cooperation must come on its terms, emphasizing the indivisibility of EU membership benefits and responsibilities. The EU’s former chief Brexit negotiator, Michel Barnier, warned that the conditions for rejoining are clear and restrictive, with no allowance for "cherry-picking" of EU rules.
Within the UK, political consensus on the issue is far from settled. Burnham’s predecessor, Labour leader Keir Starmer, sought to improve trade relations with the EU without returning to key elements of the original membership, such as free movement or full single market access. Analysts suggest that Burnham’s approach represents a more direct acknowledgment of Brexit’s economic drawbacks, although some of his Labour colleagues view renewed debate as politically risky, potentially energizing right-wing parties like Reform UK.
The EU, for its part, sees strategic benefits in possibly reintegrating the UK, especially amid global geopolitical uncertainties including tensions with Russia and challenges posed by China. Some member states, particularly in Northern Europe, welcome the idea of a closer partnership, while France remains cautious, viewing the UK’s traditionally Atlanticist and liberal economic stance as a potential challenge to its vision for European strategic autonomy.
Rejoining the EU would face significant procedural hurdles in member states, notably France, where parliamentary ratification or even a referendum could be required, alongside political opposition from figures like far-right leader Marine Le Pen, who has promised to oppose further EU enlargement.
Economically, the UK now confronts challenges that have crystallized since Brexit, including supply chain shifts and EU industrial policies that may conflict with British ambitions to revitalize key manufacturing sectors. Analysts caution that intermediate solutions such as partial Customs Union membership or dynamic alignment with EU regulations may prove politically and economically untenable.
Burnham himself has not made EU advocacy a defining feature of his political career but appears increasingly motivated by economic concerns and shifting public sentiment. Polls indicate growing support for rejoining the EU, though enthusiasm diminishes when voters consider potential trade-offs like adopting the euro or reinstating freedom of movement.
His government’s forthcoming engagement with EU leaders, including a scheduled meeting with German Chancellor Friedrich Merz, is expected to test the seriousness of the UK’s renewed overtures and the EU’s appetite for reopening membership discussions. While details remain sparse, Burnham’s move has undeniably reopened a debate long considered settled, introducing a new dimension to UK-EU relations amid evolving geopolitical dynamics.
