Pressure grows on the PM over the Mandelson vetting row after a dismissed civil servant told MPs No 10 fostered a pressurised atmosphere and was dismissive of warnings. Senior Labour figures, including Ed Miliband and Yvette Cooper, signalled dissent and urged Cabinet action.

Starmer admits he was wrong to appoint Peter Mandelson as US ambassador but refuses to resign. He blames civil service vetting, alleging a deliberate cover‑up. MPs challenge his account, with Badenoch leading criticism and urging him to take responsibility.

Two senior aides knew for weeks about concerns over Peter Mandelson’s vetting for a proposed US ambassadorship, despite security advice, reports say. Critics urge the PM to take responsibility amid claims of poor oversight; he insists he learned only this week.

Sir Keir faces calls to resign after No.10 confirmed Peter Mandelson failed security vetting before being named US ambassador. Opposition leaders say he misled MPs. Starmer says officials handled checks and denies intent. No.10 has launched an investigation into how the appointment was approved.
