UK Cabinet splits over Brexit deepen – as Burnham prepares migration offer to EU

The Prime Minister’s remarks in a Sunday Times interview last week hinted that the government was “leaning into the idea of returning to open borders” as part of a broader strategy to secure a closer relationship with Brussels. Burnham, who has said he wants to “have the difficult conversation now rather than avoid it”, is expected to present a range of options—including full membership of the single market, customs union and even full re‑entry into the EU—at the summit later this month.

Chancellor John Healey, meanwhile, publicly contradicted Burnham’s stance by stating that “freedom of movement is not negotiable.” His comments have irritated No 10, raising fears that a divided government could appear unprepared to the EU leaders ahead of the summit. A senior Whitehall source described Healey’s remarks as a “personal view” rather than government policy, but the tension has already begun to surface.

Labour MPs are also voicing concerns. Melanie Onn, MP for Great Grimsby and Cleethorpes, warned that “freedom of movement is a defining factor in the Brexit vote” and that a revival could “destroy trust.” She added that the party’s 2024 manifesto had been “unequivocal” about not returning to the single market, customs union, or freedom of movement. The sentiment has spread across the party, with several MPs in former Leave‑voting constituencies echoing the message that a re‑introduction of EU migration rules could reignite divisions at a time when the country needs unity.

Business Secretary Jonathan Reynolds, who is described by some as sceptical about re‑joining the customs union, dodged questions about his personal stance. He reiterated that the government’s line is “to focus on the summit and tangible improvements” and that any discussion of free movement is “for the PM to set out.” This cautious approach reflects the broader uncertainty within the Cabinet about how to balance economic ambitions with domestic political risk.

In the weeks ahead, the UK‑EU summit on 20 November will be the crucible for Burnham’s proposals. He is expected to outline a “wider conversation” about Britain’s future relationship with Europe, including freedom of movement, after the summit. The outcome will not only determine whether the UK can secure a meaningful deal with Brussels but also whether the party can maintain cohesion behind a potentially divisive policy.

• 20 November – UK‑EU summit – Burnham will present his migration offer and the government’s stance on the single market and customs union.

While the Prime Minister has made no secret of his hope that Britain might re‑join the bloc in his lifetime, the current Cabinet division suggests that any move toward deeper EU ties will be a marathon rather than a sprint. The next few weeks will decide whether the UK can reconcile its domestic political realities with the economic incentives of a closer partnership with the EU.
