Ambassador to the United States

Sarah Bool Excerpts

Tuesday 16th September 2025 Commons Chamber

[Sarah Bool (South Northamptonshire) (Con)]

On rare moments, Members on both sides of the House come to the Chamber with the same question on their minds: how did it get to this? The Prime Minister is proud of his record as Director of Public Prosecutions and of his skill to prosecute, interrogate and investigate—skills that are absent here. He will also be more than familiar with the basic legal principle of caveat emptor—buyer beware. That can be translated across the board to many scenarios and, in essence, means that we have to do our research and ask pointed questions.

On that point, the Prime Minister exposed himself in interviews yesterday. He claimed that he did not know the content of the Bloomberg emails, yet he knew that they existed—where was the inquiry? He knew that an investigation had been launched by the Foreign Office, but not the content—where was the inquiry? He was waiting for answers from the disgraced ambassador, even though we understand that his chief of staff was in contact with him for much of the previous day—where was the inquiry? Given the knowledge that such outstanding questions remained unanswered, anyone—not just a lawyer—would have drawn breath and paused before giving such a vote of confidence in the ambassador during PMQs. It was wilful ignorance at best, or political belligerence at worst.

The Prime Minister now says:

“Had I known then what I know now, I’d have never appointed him”.

The former Foreign Secretary said:

“The truth is all the issues were weighed and in that time it was known that Peter Mandelson had a relationship with Jeffrey Epstein, but the scale and extent of that was only known last Wednesday evening when the prime minister surveyed those emails.”

We understand, however, that the Foreign Office contacted No. 10 on Tuesday and that an investigation was opened. Something does not add up.

There is such a lack of clarity on this matter, and where there is a lack of clarity, we need transparency. A proper due diligence exercise relies on the disclosure given, as the Prime Minister will be well aware from his practice. It is time to disclose. I am therefore sure that the Government will oblige the request of the Leader of the Opposition to provide the House with all correspondence and documents in the Mandelson files.

The matter, however, goes beyond judgment calls made by the Prime Minister and the previous Foreign Secretary, given that both are involved in the appointment of ambassadors; it is also a matter of ethics. What is deemed acceptable behaviour for those in positions of power? The Nolan principles are integral to all of us who serve the public: selflessness, integrity, objectivity, accountability, openness, honesty and leadership. Those principles apply as much to the former ambassador as to the Prime Minister. Under “Leadership”, the principles state:

“Holders of public office should…actively promote and robustly support the principles and challenge poor behaviour wherever it occurs.”

Given the known record of Peter Mandelson, even before the details of the Bloomberg emails came to light, does the Prime Minister believe that that principle has been met? On that basis, will the Prime Minister be referring himself and others involved in the appointment process to the independent ethics adviser?

The role of ambassador in Washington is a crucial one, entrusted with the most sensitive information and shaping our reputation on the world stage. It is not too much to ask that its appointee embodies the highest standards.
