The PM vows to carry on after a mooted leadership challenge fizzled, promising a reset and possible reshuffle. Cabinet ministers lined up in support as critics retreated, while Wes Streeting was accused by colleagues of bottling a bid. Focus now shifts to policy delivery.

Morgan McSweeney has resigned as the PM’s chief of staff after criticism of his backing for Lord Mandelson and concerns over exchanges with a former ambassador. No 10 says the PM is not considering his position. The move is intended to steady operations and refocus on delivery.

Angela Rayner says she warned Starmer not to appoint Lord Mandelson as ambassador to the US, citing concerns over his links with Jeffrey Epstein following Epstein’s conviction for abuse. Detectives have searched properties linked to Mandelson as part of an investigation.

The PM apologised for accepting Lord Mandelson’s assurances about past links to a disgraced financier before backing him for a top diplomatic post. Labour figures branded him gullible and weak and urged a rethink, deepening unrest over the appointment.
