Sir Keir Starmer Alleges Foreign Office Withheld Lord Mandelson Vetting Failure Data

Sir Keir Starmer has publicly accused Foreign Office officials of a deliberate and repeated effort to withhold information regarding Lord Mandelson's initial failure to pass security vetting for the United Kingdom's US ambassadorial post. Speaking to MPs, the Prime Minister asserted that had he been privy to this crucial detail, the appointment would not have advanced.

Sir Keir discovered last Tuesday that the Foreign Office had overridden the security vetting agency's recommendation to deny Lord Mandelson clearance. This revelation has prompted calls for the Prime Minister's resignation from Conservative leader Kemi Badenoch, who criticised Sir Keir for allegedly misleading the Commons and "throwing his staff and officials under the bus" rather than accepting responsibility.

The Prime Minister maintained he did not mislead Parliament, pointing to the Ministerial Code which expects ministers to correct any inadvertent errors at the earliest opportunity. The controversy surrounding Lord Mandelson's appointment has persisted for months.

Vetting Process and Official Conduct

Lord Mandelson's appointment as UK ambassador to the US was announced in December 2024, prior to in-depth vetting. He formally assumed the role on 10 February 2025 but was dismissed seven months later due to his associations with the convicted sex offender Jeffrey Epstein.

UK Security Vetting, a Cabinet Office agency, commenced the vetting process in late December 2024, recommending on 28 January 2025, that Developed Vetting clearance be denied. Foreign Office officials, however, disregarded this advice and granted clearance.

Sir Keir detailed numerous instances where this information should have been disclosed to him, including at the points of appointment and dismissal, and when he subsequently ordered a review of the vetting process. He described it as "astonishing" and "absolutely unforgivable" that the then-head of the Civil Service, Sir Chris Wormald, and Foreign Secretary Yvette Cooper were not informed.

The Prime Minister stressed, "A deliberate decision was taken to withhold that material from me. This was not a lack of asking. This wasn't an oversight. It was a decision taken not to share that information on repeated occasions."

Sir Olly Robbins, the most senior civil servant at the Foreign Office, was effectively removed from his position on Thursday, following reports that his department had contravened the security clearance recommendation. Sir Olly is scheduled to provide evidence to the Commons Foreign Affairs Committee on Tuesday morning, where Dame Emily Thornberry, the committee's chair, noted a "partial truth" had been presented previously regarding the vetting process. She questioned whether "getting Peter Mandelson the job was a priority that overrode everything else and that security considerations were very much second order" for certain team members.

Sir Keir denied any pressure from Downing Street regarding the appointment, despite Lord Mandelson's Epstein links being public knowledge. The Prime Minister also confirmed that the process has since been altered, preventing announcements of appointments until security vetting is successfully completed. Last week, the Foreign Office's authority to make final decisions on security clearance was suspended.

Other political leaders, including Sir Ed Davey of the Liberal Democrats and representatives from Reform UK, the Green Party, Plaid Cymru, and the SNP, have called for Sir Keir's resignation, citing a "catastrophic error of judgement" and accusations of misleading the public.
