Cabinet figures are losing confidence in the PM after a security row linked to Mandelson, with one minister saying patience has run out. Allies of Wes Streeting are open to a pact with Angela Rayner to unite centre and left and avert a leadership fight, though policy gaps and an HMRC inquiry pose hurdles.

At an MPs hearing, ex-Foreign Office chief Sir Olly Robbins said No 10 pressed officials to push through vetting and an ambassador role for a politically connected figure, contradicting the PM. Senior ministers voiced concern, while No 10 said the proper process was followed.

The PM says officials repeatedly hid that Peter Mandelson failed security vetting for the Washington ambassador role, calling it an “unforgivable” cover‑up. He sacked Sir Olly Robbins, who faces MPs and is negotiating his exit. Starmer denies misleading Parliament or breaching the ministerial code, rejecting calls to resign.

The PM will explain the Peter Mandelson security vetting fiasco and why he dismissed the head of the Foreign Office. Ministers say he was kept in the dark and did not mislead MPs. He faces Commons questions, with Sir Olly Robbins due to appear tomorrow.
