Mandelson Vetting Scandal Labelled Biggest Diplomatic Crisis in Decades
Simon McDonald, the former permanent under-secretary of the Foreign Office until 2020, has declared the Peter Mandelson security vetting scandal as the most significant crisis to hit the diplomatic service in decades. In a stark assessment, McDonald defended Oliver Robbins, the civil servant dismissed from his role, asserting that Robbins was unfairly "thrown under a bus" by Prime Minister Keir Starmer.
Dismissal and Allegations of Unfair Treatment
Robbins was sacked as permanent secretary of the Foreign Office shortly after the Guardian revealed that Peter Mandelson failed his security vetting in January 2025 during the process to appoint him as ambassador to the US. Robbins is reported to have known about Mandelson's failure to pass the UK Security Vetting assessment but did not forward this information to ministers. Starmer claims he was unaware of the vetting outcome until this week, leading to Robbins' dismissal.
McDonald, speaking on the BBC's Today programme, agreed with Robbins' belief that he was following due process and was treated unfairly. He stated, "Yes, this story broke on Thursday morning in a piece in the Guardian; within the news cycle Olly Robbins had been required to resign." McDonald criticized the swift action, suggesting it showed "No 10 required a scalp and wanted it quickly," and added, "I cannot see that there was any process, any fairness, any giving him the chance to set out his case and that feels, to me, wrong."
Broader Implications and Government Response
The scandal has escalated with Robbins expected to present his side of the story before the Commons foreign affairs select committee on Tuesday. Ministers are concerned he may use this platform to challenge No 10's narrative, potentially damaging Starmer's administration. McDonald implied that the government misrepresented events to shift blame, noting that the decision to appoint Mandelson, despite civil service concerns, was made by the prime minister.
He explained, "The whole posting was controversial. By the time Olly Robbins became permanent secretary in the Foreign Office, the posting had been announced, it was clear that the prime minister wanted his man to go to Washington, and the system was making that happen." The Cabinet Office released a template from the UKSV summary document, which indicated Mandelson's vetting concluded with a "high" overall concern and "clearance denied," but this was overruled by the Foreign Office using rare authority.
Cover-Up Allegations and Prime Minister's Reaction
McDonald suggested the vetting process was more complex than presented, saying, "If it did amount to failure then that fact would have to be conveyed to the political level, but the fact that it was not indicates to me that the fact was rather more complicated than No 10 would wish to present." Starmer expressed fury over the situation, with Downing Street blaming the Foreign Office for not informing him repeatedly. When asked if this constituted a cover-up, a spokesperson did not deny it, stating, "Well, the prime minister was not informed and he's made clear that it is staggering that he was not informed."
Further revelations from the Guardian indicate that Starmer was also kept in the dark by two other top civil servants, cabinet secretary Antonia Romeo and Catherine Little, the Cabinet Office's permanent secretary, who knew of the situation last month but did not immediately inform the prime minister. This deepening scandal underscores ongoing tensions within the government and raises questions about transparency and accountability in high-level appointments.
