The Mayor of London, Sadiq Khan, has issued a direct appeal to the Labour Party, urging it to include a pledge to rejoin the European Union in its manifesto for the next general election. In an interview with the Italian newspaper La Repubblica, Sir Sadiq outlined a comprehensive roadmap for rebuilding closer ties, advocating for re-entry into both the customs union and the single market.
Brexit's Damaging Impact Highlighted
Sir Sadiq emphasised the profound negative consequences of Brexit, stating: "I see on a daily basis the damage Brexit has done to not just London, but to Londoners, the damage economically, socially and culturally." He was unequivocal in his stance, declaring: "I’m quite clear in terms of what needs to happen, which is, we should join the European Union."
Changing Global Landscape
The Mayor pointed to several factors that he believes justify revisiting the issue, including the election of US President Donald Trump, increasing global instability, and the passage of time since the original Brexit decision. He argued that "the facts have changed" and "the evidence has changed," making a strong case for Labour to adopt a clear pro-EU position.
Sir Sadiq insisted: "We should, as a Labour Party, fight the next general election with a clear manifesto commitment, a vote for Labour means we would rejoin the European Union. I think it’s inevitable."
Starmer's Approach to EU Relations
Prime Minister Sir Keir Starmer has pursued a strategy to "reset" relations with Brussels since his election in 2024, focusing primarily on improving trade ties. This approach contrasts with Sir Sadiq's more ambitious call for full rejoining, highlighting potential divisions within the party on Europe.
Chancellor's Warning on Trade
Chancellor Rachel Reeves added to the debate earlier this week, warning that the UK risks being "stranded" between rival trading blocs unless it forges closer ties with Brussels. She indicated that any divergence from EU regulations would be limited, describing it as "the exception, not the norm."
Ms Reeves reinforced this view, stating: "Our fate as a country is inescapably bound with that of Europe."
Upcoming UK-EU Agreements
By the time of the next joint summit later this year, the UK and EU aim to finalise several key agreements. These include establishing a youth mobility scheme, creating a common sanitary and phytosanitary area, and linking their emissions trading systems, reflecting ongoing efforts at cooperation.
Government's Red Lines on Rejoining
In February, Downing Street dismissed the prospect of rejoining the customs union after European economic commissioner Valdis Dombrovskis indicated the bloc would be open to discussions. No 10 sought to pour cold water on the idea, emphasising that Sir Keir Starmer’s Government would stick to its red lines as it deepens ties with the EU.
The Prime Minister’s official spokesman clarified: "We will not be rejoining the customs union, the single market or returning to freedom of movement. Those are our red lines as per the Government’s manifesto. We do want a closer economic partnership with the EU, but rejoining the customs union would unpick important trade agreements we’ve reached, including our deals with the US and India."
