Sir Sadiq Khan Urges Labour to Campaign for EU Rejoining

London Mayor Demands Labour’s Bold EU Commitment Ahead of 2029 Election

Sir Sadiq Khan, the Mayor of London, has delivered a powerful challenge to the Labour Party: commit unequivocally to rejoining the European Union before the next general election, anticipated in 2029. Khan insists that reversing Brexit’s far-reaching consequences requires the UK to not only seek EU membership again but also to re-enter the customs union and single market. His call signals a dramatic shift in the political conversation surrounding Britain’s post-Brexit future, urging Labour to adopt a bold stance that could reshape national policy and economic strategy.

What Happened: Khan’s Vision for the UK’s Future in Europe

Brexit’s Lasting Damage and the Case for Rejoining

In a candid interview with the Italian newspaper la Repubblica, Sadiq Khan articulated a stark assessment of Brexit’s impact on the United Kingdom. He described the consequences as “economic, social, and cultural damage” that have not only affected London but reverberated throughout the country. Khan pointed out how global pressures, such as US-imposed tariffs and geopolitical instability in Iran, have exacerbated the ongoing cost-of-living crisis, intensifying challenges for ordinary Britons.

By declaring that “the facts have changed. The evidence has changed,” Khan underscored his belief that the UK’s trajectory must shift toward reintegration with Europe. While he stopped short of demanding a second referendum on EU membership, he made it clear that rejoining the EU could happen without one. This nuanced position highlights the complexity of public opinion and political feasibility surrounding Brexit reversal.

Government Resistance and Conservative Backlash

The UK government, led by the Conservative Party, continues to reject proposals for re-entry into the customs union or the single market, maintaining a firm post-Brexit stance. Downing Street views such moves as a threat to the sovereignty and independence that Brexit supporters championed. In response to Khan’s remarks, Conservative spokespeople quickly criticized the proposal, framing it as evidence of Labour leader Sir Keir Starmer being “in office but not in power.”

The criticism extended to Labour’s internal cohesion, accusing prominent figures like Ed Miliband and Angela Rayner of overriding Starmer’s authority on crucial foreign and immigration policies. One Conservative spokesperson emphasized, “Only Kemi Badenoch’s Conservatives are serious about cutting welfare, cutting taxes and getting Britain working again,” thereby positioning the Conservative Party as the steadfast guardian of Brexit’s legacy and economic reform.

Wider Political Reactions and the Asylum Policy Debate

Calls for Compassionate Asylum Reforms

Alongside his advocacy for EU rejoining, Khan has called for a more humane approach to the government’s planned asylum reforms. These reforms have sparked significant disagreement within the Labour Party, with many members publicly opposing the government’s tougher stance on migrant settlement rules. Khan aligned himself with voices like Angela Rayner, who recently labeled the stricter policies as “un-British” and “a breach of trust.”

Khan stressed the importance of integration and contribution, stating, “We want people, if they come here, to properly contribute, to integrate and get involved.” This perspective emphasizes a vision of immigration policy that balances compassion with social cohesion, reflecting growing tensions within Labour between pragmatism and principle.

Mixed Responses Across the Political Spectrum

Reactions to Khan’s EU rejoining proposal have varied widely. Reform UK, a party firmly opposed to reversing Brexit, dismissed any prospects of reintegration and vowed to undo such moves if elected. Meanwhile, Green Party leader Zack Polanski lamented the wide-ranging social, cultural, and economic damage Brexit has wrought and expressed hope that the UK might eventually return to the EU. Polanski criticized Brexit advocates like Nigel Farage for claiming to solve problems they helped create, highlighting deep divisions over the issue.

The Liberal Democrats echoed Khan’s concerns, emphasizing the urgency of repairing Brexit’s economic consequences. They argued that rejoining the customs union is essential not only to boost the economy but also to mitigate the cost-of-living crisis and enhance funding for public services. This stance aligns with the party’s long-standing pro-European platform and its efforts to influence post-Brexit policy direction.

What Comes Next: Economic Realities and Political Implications

Sir John Major’s Economic Warning

Adding weight to the debate, former Conservative Prime Minister Sir John Major recently delivered a keynote speech at King’s College London, condemning Brexit for failing to deliver its promised benefits. Major estimated that Brexit has cost the UK approximately £100 billion annually in lost European trade and £40 billion in tax revenue. He warned that Brexit has left the UK isolated and vulnerable on the global stage, though he stopped short of endorsing full EU rejoining in the near term.

“Economic wellbeing tells us we should re-build relationships with our closest neighbours as swiftly and as comprehensively as possible,” Major concluded, underscoring the economic imperative behind calls for closer UK-EU ties even among some former Conservative leaders.

Ongoing Political Developments

  • Prime Minister Keir Starmer has publicly rejected rejoining the EU customs union, despite ongoing debate within Labour’s ranks.
  • EU Commissioner has signaled openness to discussions with the UK regarding customs union arrangements, leaving the door ajar for future negotiations.
  • Tensions over the post-Brexit trade deal continue to influence UK-EU relations, affecting commerce, regulatory standards, and political trust.

Why It Matters: The Stakes for Britain’s Future

Sadiq Khan’s call for Labour to champion EU rejoining ahead of the 2029 election represents more than a policy proposal, it challenges the prevailing political consensus shaped by nearly a decade of Brexit debate. His stance confronts the economic hardships and social divisions that have emerged post-Brexit, framing re-entry into the EU as a pragmatic solution to restore prosperity and international cooperation.

The sharp Conservative opposition underscores the polarized nature of Britain’s political landscape, where Brexit remains a defining and divisive issue. Meanwhile, Labour’s internal debates reflect broader uncertainties about how best to navigate the country’s future relationship with Europe and the world.

As the UK approaches another critical election cycle, the question of EU membership and customs union participation will likely dominate political discourse. Whether Labour embraces Khan’s vision or maintains a more cautious approach could significantly influence voter sentiment, economic recovery, and the nation’s global standing.

Ultimately, Khan’s intervention invites voters, politicians, and policymakers alike to reconsider the path forward amid changing economic realities and geopolitical challenges.
