Sir Olly Robbins, recently dismissed as permanent under-secretary at the Foreign Office, delivered compelling testimony to the foreign affairs committee, highlighting intense pressure from Downing Street to expedite security vetting for Peter Mandelson’s appointment as UK ambassador to the US.
In over two hours of evidence, Sir Olly, a 51-year-old career civil servant, explained that No 10 insisted on placing Mandelson in Washington DC ahead of Donald Trump’s inauguration on January 20, 2025, regardless of potential risks. He described relentless follow-ups from Downing Street throughout January, creating an unmistakable urgency to finalize the process swiftly.
Fast-Tracking Mandelson’s Appointment
Sir Olly assumed his Foreign Office role on January 8, 2025, shortly after Mandelson’s appointment announcement by Prime Minister Keir Starmer. He stated: ‘I walked into a situation in which there was already a very strong expectation that he needed to be in post and in America as quickly as humanly possible.’
No 10 had previously instructed his predecessor to proceed ‘at pace.’ By Sir Olly’s arrival, the King and the White House had already endorsed the nomination. He noted an ‘atmosphere of constant chasing,’ with queries like ‘has this been delivered yet?’
Sir Olly could not confirm if the Prime Minister’s then-chief of staff, Morgan McSweeney—a protégé of Lord Mandelson—orchestrated the pressure, though handover discussions conveyed significant urgency.
Downing Street’s Dismissive Stance on Vetting
Sir Olly submitted a key letter to the committee, underscoring No 10’s commitment to the posting. He revealed that officials bypassed standard protocol by announcing the appointment before completing security clearance and even questioned the need for developed vetting (DV) due to Mandelson’s status as a peer and Privy Counsellor.
The Foreign Office insisted on proceeding with checks, but the announcement preceded them, granting Mandelson access to classified briefings prematurely. Sir Olly characterized this as a ‘dismissive approach.’
Managing Security Concerns
At the scandal’s core, Sir Olly approved Mandelson’s DV clearance despite UK Security Vetting (UKSV) reservations. He rejected claims of overruling experts, noting he received only an oral briefing from Foreign Office security head Ian Collard on January 29.
Sir Olly recounted: ‘UKSV considered Mandelson a borderline case, leaning towards recommending clearance denied, but the Foreign Office security department assessed the risks as manageable and/or mitigable.’ The issues did not involve Mandelson’s association with Jeffrey Epstein, though details remained confidential.
Confidentiality and Notification Lapse
Despite the pressure, Sir Olly did not inform No 10 of the concerns or approval immediately, citing vetting confidentiality protocols. He emphasized: ‘The decision-making within the box of the vetting process must remain entirely confidential.’
This omission contributed to his dismissal after the Epstein links surfaced, leading to Mandelson’s removal. Sir Olly viewed demands for disclosure as a ‘dangerous misunderstanding.’
He also disclosed No 10’s prior lobbying for disgraced spin doctor Matthew Doyle as an ambassador, adding to the revelations.
Averting a Diplomatic Crisis
Sir Olly acknowledged that rejecting Mandelson’s clearance could have strained UK-US ties, especially with the incoming Trump administration. He stated: ‘It would have caused a real problem for the Government and a problem for the country.’
However, he criticized the early announcement despite known reputational risks: ‘I regret that this process was not done before announcement… serious reputational risks didn’t colour the Prime Minister’s judgment.’
Potential Legal Challenge to Dismissal
Sir Olly expressed deep sadness over losing his role, hinting at possible legal action. He declined to detail his sacking conversation with the Prime Minister, saying: ‘I regret that those [reasons] were not put to me before I received a letter dismissing me.’
He described his situation as ‘unknown territory’ regarding HR matters, underscoring unresolved questions about his accountability.
