Starmer under fire as Mandelson vetting scandal deepens

Pressure on Sir Keir Starmer hardened into a test of command on Friday as the Mandelson vetting row stopped looking like a personnel mistake and started looking like a failure of control inside the heart of government. Starmer said it was “furious” and “staggering” that neither he nor any minister had been told Lord Peter Mandelson had failed security vetting before his appointment as UK ambassador to the United States.

The issue now reaches beyond Mandelson’s record and into the machinery that put him there. Reporting has said Mandelson was named publicly as the government’s nominee before the vetting process had finished, and that the initial security recommendation was negative before the Foreign Office intervened. That has put the Foreign, Commonwealth & Development Office, No 10 and the wider chain of accountability under the sharpest scrutiny, especially after Sir Olly Robbins, the Foreign Office’s most senior civil servant, was removed after the department overruled the vetting advice.

Starmer has said he will set out the relevant facts in Parliament on Monday, a signal that Downing Street understands the damage is now political as much as procedural. Opposition figures have already stepped up their attacks, with calls for Starmer to resign and accusations that he may have misled MPs. The central question is no longer simply whether Mandelson should have been appointed, but whether the prime minister’s own operation failed to surface an intelligence warning serious enough to derail the post before it became a public embarrassment.

The row has also reopened the wider argument about judgment at the top of Labour’s government. Mandelson’s ties to Jeffrey Epstein had already intensified criticism of the appointment, and the vetting controversy has made that criticism harder for Starmer to contain. It has created the impression of a system that either did not ask the right questions or did not act on the answers.

The timing is awkward too, coming alongside the government’s attempt to project competence on Gibraltar. On 26 February 2026, the UK Government and the European Union published draft treaty text after four years of negotiations, in a deal designed to remove checks and physical barriers at the Gibraltar-Spain border while protecting UK sovereignty and military autonomy. For Starmer, however, the Mandelson affair now risks overwhelming any diplomatic gains and raising a more corrosive question: whether this is a one-cycle stumble, or evidence that Labour’s political management is already fraying under the pressure of office.
