Lord Mandelson

Debate between Mike Martin and Emily Thornberry

Wednesday 4th February 2026 Commons Chamber

[Emily Thornberry]

I will not take any more interventions.

I have explained what our Committee was told about due diligence and how that happened. Normally what would then happen is that an interview would be done with a panel, and questions that arose during due diligence would be put to the candidate during that interview. But that did not happen in this case because it was a political appointment. So if anyone had any concerns about Peter Mandelson and his background, or any of the things that people are now concerned about, those would not have been formally put to him during any form of interview process where minutes were taken and we could now look at what those conversations were. That, I think, is a really important piece of information to put before this House so that people understand how this happened.

We have due diligence—fast-streamers looking at the internet—nothing being put to Peter Mandelson, and then the decision being announced. The decision was announced in the middle of December, as we have heard, and then they wanted to do it really quickly, presumably so that he could be at the President’s swearing-in. Also, once the announcement was made, Karen Pierce would have lost power and influence, because it would have been known that she was not continuing in post, so it was important to move as soon as possible.

The next stage was vetting, which is done by the Foreign Office. The question I have for Ministers is this: given that the announcement had been made and that speed was needed, was pressure put on the Foreign Office to get through the vetting quickly? Was there, to coin a phrase, a need to “get on with it”? That is an important question to ask and one that we need an answer to, but we must also be realistic. Once it was known that Peter Mandelson was going to be the ambassador for Britain, it would have taken huge bravery and introduced potential risk to withdraw him from the appointment if anything had come up at the vetting stage.

[Mike Martin]

As Chair of the Foreign Affairs Committee, does the right hon. Lady know what the then Foreign Secretary—the Deputy Prime Minister, the right hon. Member for Tottenham (Mr Lammy)—knew at that time? Does she think that that should also be brought to the attention of the House in this release of documents?

[Emily Thornberry]

The point is that the due diligence and vetting are done by civil servants and are not supposed to involve politicians, and the decision was made in No. 10. That is how it works, as I understand it, so the views of the then Foreign Secretary may not be directly relevant.

[Mike Martin]

I thank the right hon. Lady for giving way once again; she is being very generous. What is the point in civil servants doing due diligence if that information is not given to politicians when they make the decisions?

[Emily Thornberry]

No, it is given to those who are making the decisions—as I understand it. The due diligence is done by the Cabinet Office. It does due diligence on a number of candidates, and then the decision is made as to which candidate will be put forward. Then it is announced. Then the vetting is done by the Foreign Office, and that information is handed back. I believe that that is the process. I think it is important, for clarity, that people know the process, because if we are about to get a large amount of information, it is important to understand how it worked.
