Brussels Watches as Starmer Fights for His Political Life

More than 90 Labour MPs have now publicly called for Sir Keir Starmer to resign as Prime Minister, following the catastrophic performance of the governing party in the 7 May 2026 English local elections. Labour lost roughly 1,500 council seats; Nigel Farage’s Reform UK gained 1,454 and took control of Essex County Council, Havering (its first London local authority) and the city of Sunderland.

For Brussels, the unfolding political crisis in London carries strategic weight that goes well beyond the personal fortunes of any particular Prime Minister. Since taking office in 2024, Starmer has pursued the most explicit policy of EU-UK re-engagement of any British leader since Brexit — and a change of premiership now puts that trajectory in doubt.

The Rayner intervention

The most damaging public intervention came from Angela Rayner, Starmer’s former deputy. On social media she wrote: “What we are doing isn’t working, and it needs to change. This may be the Labour Party’s last chance.” The post was read across Westminster as a positioning move for a possible leadership contest. Other potential challengers include Health Secretary Wes Streeting and Manchester Mayor Andy Burnham, though Burnham would need first to win a seat in Parliament.

Starmer himself has refused to step down. In a make-or-break speech on Monday 11 May at Downing Street, he insisted he would lead Labour into the next general election due in 2029. “To meet the challenges that our country faces, incremental change won’t cut it,” he said, acknowledging that “some people are frustrated with me” and that he has “doubters.” He framed his government as a “10-year project of renewal.”

The view from the Berlaymont

European Commission officials have, with one or two undiplomatic exceptions, declined to comment on the British political situation in public. In private, the assessment is markedly more guarded than it would have been a year ago. The Starmer-von der Leyen Strategic Reset of May 2025 — which produced the new fisheries agreement, the SPS deal, and the youth mobility framework — has been a personal project for Starmer in particular.

A successor from the harder left of the Labour Party might pursue closer alignment with EU regulation, including possible accession to the customs union — a politically explosive proposition in the UK but one welcomed in many EU capitals. A successor from the centre-right of the party, by contrast, might be more cautious, particularly under pressure from a resurgent Reform UK. Worst of all, from Brussels’ perspective, would be a Labour collapse opening the way to a Reform UK government with a fundamentally adversarial posture toward the European project.

Markets render their verdict

Financial markets have made the political risk concrete. The yield on the 10-year UK government bond pushed above 5% earlier this month, reflecting investor anxiety that a more left-leaning successor could loosen fiscal discipline. The FTSE 100 fell 2.00% on Friday’s close to 10,165 points, while sterling traded at a one-month low against the dollar.

Chancellor Rachel Reeves, defending the Starmer line, said Thursday’s Q1 GDP figures — UK growth of 0.6%, in line with expectations — showed the government “has the right economic plan.” Her own future is widely seen as tied to the Prime Minister’s.

The political calculation now turns on whether any challenger can muster the 81 nominations required to formally trigger a contest before Parliament rises for the summer recess. None has yet broken cover. For Brussels — and for European leaders preparing for the next round of EU-UK negotiations on financial services and youth mobility — the answer to that question over the next eight weeks will determine the political weather across the Channel for years to come.
