LONDON (AP) — Efforts to unseat British Prime Minister Keir Starmer from within his own party broke into open rebellion Thursday, with one potential rival resigning from the Cabinet and two others positioning themselves for a future leadership challenge. Health Secretary Wes Streeting became the first senior minister to quit Thursday in what was seen as a precursor to challenging Starmer’s leadership. He said he had lost confidence in Starmer, who should not serve out the rest of his term. “You have shown courage and statesmanship on the world stage — not least in keeping Britain out of the war in Iran,” Streeting wrote in an excoriating resignation letter. “But where we need vision, we have a vacuum. Where we need direction, we have drift.”But Streeting stopped short of saying he was the best candidate to lead the party at the next election due by 2029, suggesting Starmer should step aside to allow a “broad” field of candidates to debate the future of the party.

Starmer is under growing pressure to step down after disastrous results for his Labour Party last week in local and regional elections. The election drubbing cemented doubts among many party members about Starmer’s judgment, vision and leadership ability — a brutal indictment on a leader who returned Labour to power in July 2024 after 14 years in opposition.
