British papers explore what’s next for prime minister Keir Starmer after the loss of his longtime adviser over the Mandelson-Epstein files scandal

The fate of prime minister Keir Starmer dominates the UK front pages on Monday after his embattled chief of staff, Morgan McSweeney, resigned over the appointment of Peter Mandelson as ambassador to Washington.

In standing down, McSweeney admitted the decision to advise sending Mandelson to the US despite his links to convicted sex offender Jeffrey Epstein “was wrong”. “I advised the prime minister to make that appointment and I take full responsibility for that advice,” he said, after a Sunday phone call with Starmer.

“Starmer fights to regain control over party after McSweeney exit” is how the Guardian framed Starmer’s predicament. Senior Labour sources said McSweeney’s departure left the prime minister dangerously exposed as he headed towards a series of policy and electoral challenges – including the Gorton and Denton byelection.
