Ambassador to the United States

Liz Saville Roberts Excerpts

Tuesday 16th September 2025 Commons Chamber

[David Davis (Goole and Pocklington) (Con)]

I beg to move,

That this House has considered the appointment process and the circumstances leading to the dismissal of the former United Kingdom Ambassador to the United States, Lord Mandelson.

Sometimes exquisite coincidences happen in this place. We have just seen a Bill presented on the topic of public office accountability by the immediate past Foreign Secretary, the now Justice Secretary. I will just read to the House the first line of its description:

“a Bill to impose a duty on public authorities and public officials to act with candour, transparency and frankness”.

I think I might return to those issues in the course of what I have to say.

As I have said, this is a matter of utmost concern across the House. It is an issue that does not just concern the Conservative party, the Scottish National party or the DUP; Members from all parts of the House are worried about it, as we have seen in the newspapers. The Government have key questions to answer, and as I said yesterday, the central question is: who knew what, and when? Let us be clear, though. There are many questions on many levels in this matter, and the Government must answer them all; so far, they have singularly failed to do so.

The questions fall naturally into four categories. First, was Peter Mandelson ever an appropriate character to appoint as our ambassador? [Hon. Members: “No.”] Well, we will get to that later. Secondly, what was the procedure for vetting, was it properly followed, and why has it gone so horribly wrong? Thirdly, what has happened in the last couple of weeks to lead to the demise of the former ambassador—who made the critical decisions and why? Fourthly, what do we do now? How do we make this Government tell the House and the nation the truth, the whole truth and nothing but the truth—which in itself would be a novelty for Lord Mandelson?

Let us begin with whether Lord Mandelson was ever an appropriate selection. As I said yesterday, our ambassador in Washington stands at the nexus of our most important bilateral relationship. For those who have not served in government, it is the one bilateral relationship run by No. 10, not the Foreign Office. That is because it is so important, and it is a role of exceptional sensitivity. More classified information crosses the ambassador’s desk than gets to most Cabinet Ministers. Indeed, in British embassies, the agencies report to the ambassador. It is not the same in American embassies, where the CIA does what it wants. Our agencies report to the ambassador, so it is a sensitive post.

Today, Peter Kyle—I have forgotten his new post—said that global circumstances dictate that the position of this particular ambassador is more important than it has ever been, and it could easily go terribly wrong. The failure to appoint the right person has already had a serious and deleterious impact on the national interest.

[Liz Saville Roberts (Dwyfor Meirionnydd) (PC)]

The Prime Minister staked his special relationship with the US President on the diplomatic skills of an ambassador who had a special relationship with the world’s most notorious child sex offender. I am sure that the right hon. Gentleman agrees that the Prime Minister’s judgment and the UK’s presence on the world stage have been diminished by this affair.

[David Davis]

There is no doubt that the right hon. Lady is correct. Frankly, I am going to try not to make this ad hominem about the Ministers who made decisions; we need to make that decision later, as it were. She is right that it has diminished the standing of our Prime Minister, and I regret that. Although we are the Opposition, I want this Government to succeed in the national interest, and this is doing the opposite of that. The ambassador’s conduct, both prior to appointment and during, must reflect the highest standards of integrity—that is fundamental, and it is true for any ambassador.
