Introduction to the Mandelson Vetting Controversy
The prime minister has stated that ministers were unaware of key details, while associates of the former senior civil servant suggest politicians may have deliberately ignored the situation.
Committee Hearing on Mandelson’s Appointment
On 3 November 2025, during a session of the cross-party foreign affairs select committee, senior civil servants including Sir Chris Wormald, then cabinet secretary, and Sir Olly Robbins, the most senior civil servant in the Foreign Office, appeared noticeably tense. This followed the removal of Peter Mandelson from his ambassadorial post in the US two months earlier after the disclosure of Jeffrey Epstein’s emails.
MP Fleur Anderson questioned the vetting and due diligence process behind Mandelson’s appointment, asking:
“In general, what is the end product of all that vetting? Does it all get put into one report? Who receives that report?”
Wormald responded:
“The report is received by the employing department and employing line manager – in this case, that would be Sir Oliver. And then a decision is taken on whether the relevant level of security clearance is to be granted and what mitigations, if any, are required.”
Anderson further inquired if Wormald himself was made aware of the security services’ findings. Robbins interjected, clarifying that decisions at his level were typically reserved for matters requiring senior judgment and risk mitigation discussions. The committee never established the extent of Wormald’s knowledge. Wormald was appointed the country’s highest civil servant in February 2026.
’s Revelation and Political Reactions
revealed that Robbins approved Mandelson’s appointment despite his failure in security vetting, intensifying questions about who knew what and when. The prime minister emphasized that politicians were kept uninformed, stating on Friday:
“That I wasn’t told that he’d failed security vetting when I was telling parliament that due process had been followed is unforgivable. Not only was I not told, no minister was told and I’m absolutely furious about it.”
Perspectives from Downing Street and Civil Servants
Individuals familiar with Downing Street expressed skepticism that Robbins did not seek justification for overruling the vetting team’s conclusion. One source remarked:
“These appointments are usually so careful. If the prime minister’s word is accepted, that neither he nor the then foreign secretary, David Lammy, knew, could it really be the case that Wormald was not let in on the secret?”
Friends of Robbins defended his actions, explaining that as permanent secretary, Robbins was the final step in the process. Robbins had indicated to the select committee that the main challenge was ensuring no conflict of interest between Mandelson’s new role and his consultancy, Global Counsel. Upon confirming this, Robbins followed security services’ advice and granted clearance based on the overall evidence.
A critical factor was the prime minister’s clear desire to have Mandelson in the position, leading the Foreign, Commonwealth & Development Office (FCDO) to act accordingly, as Robbins told the committee.
Some civil servants critical of Robbins acknowledged the circumstances. One stated:
“I loathe Olly – he is arrogant to colleagues and condescending to ministerial authority – but it isn’t fair for him to be sacked just for doing what the prime minister wanted to happen.”
Conversely, a colleague sympathetic to Robbins described his position as untenable, noting that Mandelson’s appointment had been announced before Robbins, recently appointed head of the FCDO, completed the vetting process. They questioned:
“Was his first big act really going to be to tell the prime minister that this could not go ahead?”
Political Oversight and Official Correspondence
Friends of Robbins suggest politicians deliberately overlooked Mandelson’s fast-tracked vetting despite evident risks. Darren Jones MP, chief secretary to the prime minister, expressed surprise that a permanent secretary could override vetting conclusions without ministerial notification.
However, this stance conflicts with documented evidence. In September, following Mandelson’s resignation, Emily Thornberry, chair of the foreign affairs select committee, wrote to the new foreign secretary, Yvette Cooper, inquiring about security concerns raised during vetting and the FCDO’s response, including any conditions imposed or decisions to dismiss concerns.
Cooper and Robbins jointly replied:
“We do not comment on the details of individual clearances or national security as a matter of course. The UK government’s national security vetting charter includes an undertaking to protect personal data and other information in the strictest confidence … The process is also independent of ministers who are not informed of any findings other than the final outcome. This remained the case in this instance.”
Regarding whether security concerns were dismissed and who decided to disregard them, Cooper and Robbins stated:
“It is not a process which involves No 10.”
This letter implies that only Robbins was aware of any concerns and mitigations, with the foreign secretary accepting that it was not her or Downing Street’s role to investigate further.
Prime Minister’s Statements and Support for Robbins
Meanwhile, the prime minister assured parliament that due process was followed and claimed that an independent vetting process involving security services had granted Mandelson clearance for the role.
A friend of Robbins commented:
“I think Olly has been treated appallingly. He has been deputy national security adviser, director of intelligence and security, it is not as if he doesn’t know his stuff.”
They added:
“This is just the death throes of a prime minister desperately trying to stay in his job.”
