Sir Olly Robbins Exposes Downing Street Pressure in Lord Mandelson US Ambassador Vetting, Reveals New Matthew Doyle Claims

Sir Olly Robbins, appearing before the Commons Foreign Affairs Committee, confirmed he did not inform Number 10 about specific vetting concerns surrounding Lord Mandelson's proposed appointment as US ambassador. This clarification initially offered a slight reprieve for Downing Street, which had faced intense scrutiny over assumptions that the Prime Minister's team knew the full extent of the vetting process.

Mandelson Appointment and Vetting Disputes

However, Robbins' nearly two-and-a-half-hour testimony presented a devastating narrative of Downing Street's relentless pursuit of Lord Mandelson's appointment in January 2025, an appointment Sir Keir Starmer has now acknowledged as a significant error. Robbins contended that the Foreign Office was placed under considerable pressure to fast-track Lord Mandelson's security clearance. He maintained that, despite this pressure, granting clearance was the correct decision, stating the UK Security Vetting (UKSV) concerns did not relate to Jeffrey Epstein.

Downing Street, conversely, asserts there was no undue pressure but that Robbins ultimately made the wrong decision to clear Lord Mandelson. The Prime Minister's office claims UKSV indicated "high concern" with two red boxes in their warning system, suggesting a denial of clearance. Robbins, however, described a verbal briefing indicating UKSV found the case "borderline" but leaned against recommending clearance, leading him to approve it after considering mitigations. This fundamental disagreement over the severity of UKSV's concerns and their communication is expected to be further scrutinised by the committee.

New Allegations Against Matthew Doyle

Beyond the Mandelson saga, Robbins made a fresh revelation regarding Matthew Doyle, the Prime Minister's former director of communications. Robbins claimed that in March 2025, civil servants working for the Prime Minister asked him to "potentially" find an ambassadorial role for Doyle. This request came despite Doyle's controversial history, including a peerage appointment that drew criticism over his association with Sean Morton, a former Labour councillor convicted of indecent child image offences in 2017. Doyle has apologised for supporting Morton's election campaign, stating it occurred when Morton maintained his innocence.

Robbins further alleged that he was instructed by Number 10 not to discuss the prospect of a diplomatic role for Doyle with David Lammy, who was then the foreign secretary. This instruction, given Lammy's current position as Sir Keir's deputy, adds another layer of political complexity. These revelations are proving particularly damaging for Sir Keir Starmer, with senior Labour figures reportedly viewing them as indicative of the government's operational culture. The ongoing inquiry and the impending release of government documents are expected to prolong this political controversy.
