Labour MPs condemn No 10’s culture after a senior civil servant said he was pressured to approve Peter Mandelson’s US role. The row has triggered cabinet anger, calls for transparency in appointments, and questions over the PM’s judgement and No 10’s working practices.

Facing jeers in the Commons, the PM said the Mandelson affair “beggars belief”, accusing the Foreign Office of a cover‑up. He insisted No10 was not told that a former US ambassador failed security vetting for a senior post, and pledged full disclosure and investigations.

Keir Starmer was warned of red flags about Lord Mandelson before giving him a senior government role, say Whitehall sources. The PM will explain the decision to MPs, amid scrutiny of the vetting process and questions over propriety, transparency and security checks.

The PM accuses officials of misleading him over Lord Mandelson’s vetting and signals a push to rein in Whitehall. He promises reforms to curb an obstructive culture and hold mandarins accountable.
