Olly Robbins has been ‘thrown under the bus’, says former Foreign Office chief

Sir Olly Robbins was “thrown under the bus” when he was sacked from his job as the most senior civil servant in the Foreign Office , a former Whitehall mandarin has said.

Lord Simon McDonald, ex-permanent secretary in the Foreign Office, said Sir Olly was a “scalp” for Number 10 after it emerged this week the department overruled concerns raised during the vetting process to appoint Lord Peter Mandelson as British ambassador to Washington.

Sir Olly left the same job on Thursday night after Prime Minister Sir Keir Starmer and Foreign Secretary Yvette Cooper lost confidence in him.

The Foreign Office has been blamed for clearing the peer in January 2025 to begin as US ambassador, despite him failing a secure vetting process.

Lord McDonald, permanent secretary at the Foreign Office from 2015 to 2020, told BBC Radio 4’s Today programme that Number 10 “wanted a scalp and they wanted it quickly”.

He added: “I think this is the biggest crisis in the diplomatic service since I joined it in 1982.”
The Government has said the Prime Minister only found out on Tuesday that Lord Mandelson was cleared for his role as Britain’s representative in Washington against the advice of security officials.

Sir Keir said he was “absolutely furious”, and described the failure to inform him as “staggering”.

Lord McDonald was asked on the BBC programme if he thought Sir Olly “has basically been thrown under the bus”.

He replied: “Yes.

This story broke on Thursday morning in a piece in The Guardian – within the news cycle Olly Robbins had been required to resign.

“This shows to me that Number 10 wanted a scalp and they wanted it quickly and 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.”
The Prime Minister had a phone call with Sir Olly on Thursday evening, the Press Association understands.

Lord McDonald took issue with the word “failed” being used to describe the vetting process result because “it is a very black and white word”.

He said: “These things tend to be a bit murkier than that.

I mean security vetting will have incomplete information, they will be unhappy about one or two details, they’ll want mitigations to be put in place.

“And all of that happens quite regularly.

It means there are hesitations, there are imperfections, but it doesn’t amount to failure.

“If there had been a failure then that fact – that ultimate conclusion – would have to be conveyed to the political level.

“But the fact that it was not indicates to me that the picture was more complicated than Number 10 wished to present.”
Sir Olly was required to “maintain confidence” on the details under the Constitutional Reform and Governance Act 2010, he added.

“The process is set out in law and the top official at the Foreign Office was observing process according to law, and this is a confidential process – like medical records are confidential”, Lord McDonald told the programme.

“So I do not know the details of this.

What I do know is that it tends to be complicated in this kind of sensitive vetting, and there is judgment involved, and that the PUS (permanent under-secretary) of the Foreign Office (Sir Olly) was following the rules and applying his judgment as far as I can see.”
Former MI6 head Sir Richard Dearlove told LBC on Friday: “I honestly cannot believe that the parliamentary under-secretary in the Foreign Office didn’t ring up his minister who he sees every day and say, I think it was David Lammy at the time: ‘look, we have a problem, the vetters have advised’ – I think one shouldn’t use the word fail – ‘that he shouldn’t be granted a DV certificate’.

“And the idea that you don’t tell this to a minister, quite frankly, is rubbish.

What you don’t tell a minister are the reasons why the vetting certificate is being withheld but you do say, look… the advice is not to give it to him.”
Lord McDonald also told the BBC: “I think to lose the top official in these circumstances is a big blow to the Foreign Office.

“Clearly it is a very complicated, difficult, important time internationally – the Foreign Office needs a new head and needs it quickly.

“I think the process to replace Olly needs to be quick and it needs to be internal, because whoever takes his place has to be credible and qualified on day one – fortunately there are a couple of people immediately available.”
