Foreign Office Top Official Sacked After Mandelson Vetting Failure Uncovered

Sir Olly Robbins, Permanent Under-Secretary at the Foreign Office, has departed his post, effective immediately, after it emerged his department withheld critical information regarding Lord Mandelson's security vetting for the position of UK ambassador to the United States. Reports indicate Prime Minister Sir Keir Starmer and Foreign Secretary Yvette Cooper lost confidence in Sir Olly, leading to his effective sacking.

The controversy stems from a Guardian exposé revealing Lord Mandelson had not been security cleared, despite being announced as ambassador in December 2024 and formally taking up the role on 10 February 2025. He was later dismissed in September 2025 due to his association with the convicted sex offender Jeffrey Epstein.

Government Overruled Security Vetting

On Thursday, the government confirmed the Foreign Office disregarded the recommendation of the Cabinet Office's security vetting agency, UK Security Vetting, and permitted Lord Mandelson to assume the ambassadorship. Within hours of this admission, Sir Olly's departure was announced.

Sir Keir faces calls for his resignation, with opposition parties accusing him of misleading Parliament. The Prime Minister had repeatedly stated on 10 September 2025 that "full due process" was followed for the appointment, and on 5 February, affirmed that "security vetting carried out independently by the security services... gave him clearance for the role."

However, senior minister Darren Jones maintained Sir Keir was not informed of the negative vetting recommendation until Tuesday, 23 September, and therefore did not mislead MPs. Mr Jones stated that no minister was made aware of UK Security Vetting's advice or the Foreign Office's decision to overrule it at the time, citing no obligation in the rules for ministers to be informed.

Calls for Investigation

Dame Emily Thornberry, chair of the Commons Foreign Affairs Committee, has invited Sir Olly to provide evidence to the committee next Tuesday, marking his second appearance concerning the Mandelson affair. Dame Emily questioned whether the decision to override vetting was Sir Olly's own or if he received direction from elsewhere, noting that official communications on the vetting process only stated clearance was granted, omitting the critical detail that it had been overridden.

Kemi Badenoch, leader of the Conservative Party, criticised the government's explanation, suggesting it was implausible that Foreign Office officials would unilaterally override security vetting for a political appointee without ministerial direction. She asserted that "all roads lead to resignation - at some point there has been deliberate dishonesty."

Liberal Democrat leader Sir Ed Davey demanded a Privileges Committee investigation into whether Sir Keir intentionally misled Parliament, calling it "inconceivable" that ministers would not have been informed. Reform UK, the Green Party, and Plaid Cymru have also called for the Prime Minister's resignation, echoing accusations of deception.

Nigel Farage, Reform leader, suggested Sir Olly was being used as a "sacrificial lamb," asserting it was highly unlikely such a senior civil servant would make such a decision in isolation. The Scottish National Party has written to the independent adviser on ministerial standards, Sir Laurie Magnus, seeking an investigation into whether Sir Keir deliberately misled the public.

Sir Keir is expected to issue a statement to the House of Commons on Monday regarding the revelations.
