Sir Olly Robbins, the permanent under-secretary at the Foreign Office, is set to depart from his position following revelations that the department failed to inform Prime Minister Keir Starmer about Lord Mandelson’s unsuccessful security vetting for the role of UK ambassador to the United States. The fallout from this oversight has led to a significant loss of confidence in Robbins, with sources indicating he has effectively been dismissed.
The Mandelson Appointment Controversy
The controversy began when it was confirmed that the Foreign Office disregarded the recommendations from the vetting agency and allowed Lord Mandelson to assume the ambassadorial role. This decision was made despite the fact that the Prime Minister and other ministers were unaware of Mandelson’s failed vetting until earlier this week. Appointed in December 2024, Mandelson officially took up the ambassador position on 10 February 2025, only to be dismissed seven months later due to his connections with convicted sex offender Jeffrey Epstein.
Sir Keir Starmer has faced mounting pressure to resign following claims that he misled Parliament regarding the vetting process. During a session of Prime Minister’s Questions on 10 September 2025, Starmer asserted multiple times that “full due process” had been followed in Mandelson’s appointment. According to the Ministerial Code, any minister who knowingly misleads Parliament is expected to resign.
Calls for Accountability
The revelations surrounding the vetting process have reignited criticism of the Prime Minister’s judgement. Conservative leader Kemi Badenoch stated that either Starmer was aware of Mandelson’s failed vetting and chose to deceive Parliament, or he was grossly incompetent for not asking about the vetting results. Meanwhile, Liberal Democrat leader Sir Ed Davey emphasised the need for transparency, insisting that the Prime Minister should have informed Parliament immediately rather than waiting for media pressure to unveil the truth.
Other political parties, including Reform UK, the Green Party, and Plaid Cymru, have joined the chorus of voices demanding the Prime Minister’s resignation. The Scottish National Party has formally requested an investigation into whether the Prime Minister intentionally misled the public, with SNP Westminster leader Stephen Flynn labelling Starmer as either incompetent, gullible, or dishonest.
Robbins’ Tenure and Departure
Sir Olly Robbins, who previously served as Theresa May’s chief Brexit negotiator, was appointed as permanent under-secretary in January 2025. Following the controversy, Labour MP Emily Thornberry, chair of the Commons Foreign Affairs Committee, expressed her belief that Robbins had misled her committee regarding Mandelson’s vetting. Thornberry stated that crucial information about Mandelson’s vetting outcome was omitted during Robbins’ testimony.
Reports indicate that friends of Morgan McSweeney, the Prime Minister’s chief adviser who resigned in February, were unaware of the vetting results. The vetting process, conducted by UK Security Vetting, includes rigorous checks on an individual’s credit history, criminal record, and personal relationships to ensure they are not susceptible to blackmail or bribery.
The Fallout from the Vetting Process
The government has committed to releasing documents pertaining to Mandelson’s appointment following a parliamentary vote. However, there are claims that senior government officials considered withholding information about the vetting failure. Sir Keir Starmer expressed his outrage upon discovering the details of the vetting process while reviewing documents for publication.
It has been reported that David Lammy, the foreign secretary during Mandelson’s appointment, only learned that the Foreign Office had overruled the vetting agency’s decision on Thursday afternoon, further complicating the situation.
Why it Matters
This incident underscores the critical importance of transparency and accountability within government appointments. The revelations concerning Lord Mandelson’s vetting not only highlight potential failures in the vetting process but also raise fundamental questions about the integrity of political leadership. As public trust in government institutions continues to wane, it is imperative that those in power uphold the highest standards of honesty and diligence, ensuring that such lapses do not occur in the future.
