Sir Olly Robbins testifies on Lord Mandelson's vetting process

Sir Olly Robbins, the former top civil servant at the Foreign Office, is giving evidence to MPs on the foreign affairs committee about his role in vetting Lord Mandelson to be the UK's ambassador to the US.

It comes after Sir Olly was effectively sacked last week after it emerged his department had granted the peer security clearance for the role in January 2025, against the recommendation of security officials who vetted him.

Lord Mandelson formally took up the role the following month, but was sacked seven months later over his ties to the late convicted sex offender Jeffrey Epstein.

In a letter to the committee published as he was giving oral evidence, Sir Olly said that when he arrived in post at the Foreign Office on 20 January, Lord Mandelson's appointment had already been announced and agreed to by the US.

He also noted that Lord Mandelson had already been given access to the Foreign Office building as well as "highly classified briefing on a case-by-case basis".

He said these factors "resulted in a dismissive approach" to developed vetting, the process required to obtain security clearance, from Downing Street.

Sir Olly said there was a "strong expectation" coming from Downing Street that Lord Mandelson "needed to be in post and in America as quickly as humanly possible".

He said his office had been "under constant pressure" over when the vetting process would be completed.

There was "never any interest, as far as I can recall, in whether, but only an interest in when," he added.

He later said that: "Whilst I think the department felt under pressure, we were proud of the fact we'd not bowed to that pressure."

In his letter, the former civil servant said he had not seen the documentation from UK Security Vetting (UKSV), the government's in-house vetting unit, containing their vetting assessment of Lord Mandelson.

He said that instead, he was given an oral briefing, during which he was told the vetting agency considered Mandelson to be a "borderline case" and that they were "leaning towards recommending that clearance be denied".

He said UKSV acknowledged that the Foreign Office "may wish to grant clearance, with appropriate risk management".

Despite questions from Labour MP Emily Thornberry, who chairs the committee, Sir Olly declined to say if there was anything flagged during the vetting that had not already been made public.

Sir Olly said he would have advised the government to carry out Lord Mandelson's vetting before announcing the appointment.

He said former US President Joe Biden had agreed to the appointment towards the end of his term in office.

"I think if the nomination had changed after that point, the incoming administration may well have commented on it publicly and it would, yes, have caused quite an issue in the relationship," he added.
