Keir Starmer, the UK Prime Minister, is in trouble after his chief of staff, Morgan McSweeney, quit. McSweeney resigned over advising Starmer to name Peter Mandelson ambassador to Washington despite Mandelson’s ties to convicted sex offender Jeffrey Epstein. "I advised the prime minister to make that appointment and I take full responsibility for that advice," McSweeney said after talking to Starmer on Sunday. The Guardian called this a moment where "Starmer fights to regain control over party after McSweeney exit." Senior Labour sources say McSweeney’s exit leaves Starmer very vulnerable as elections approach in Gorton and Denton. The Telegraph warns that McSweeney’s resignation might not save Starmer’s job, quoting a Labour insider: "Morgan has taken responsibility for the advice. But there were plenty of others pushing for it. So how long can Starmer cling on?" Labour MP Brian Leishman said, "There must be a change in political direction and that comes from the very top." Rivals like Angela Rayner and Wes Streeting are now seen jockeying for leadership spots. The Mirror headlined McSweeney’s words "Blame me" and called it a "Labour leadership crisis." Two of McSweeney’s deputies, Vidhya Alakeson and Jill Cuthbertson, are reportedly acting chiefs of staff for now. The Times labeled the resignation a sacrifice of Starmer's closest ally. A cabinet minister speculated Starmer could quit soon: "We’re asking the question of whether he will be there at the end of the week. The next 48 hours is going to be crucial." The Financial Times noted Starmer faces tough pressure inside and outside Labour. Conservative leader Kemi Badenoch said, "Keir Starmer has to take responsibility for his own terrible decisions." The i paper said McSweeney’s departure might ease some party worries but called Starmer "fatally wounded ... a dead man walking." The Express asked: "Are Starmer’s days numbered as key aide resigns?" Starmer now faces intense scrutiny to save his premiership after this setback.
