Lord Mandelson: Response to Humble Address

Debate between Emily Thornberry and John Hayes

Wednesday 3rd June 2026 Commons Chamber

[Emily Thornberry]

I suspect that the ISC may have been entrusted with it—that is what I am trying to say. I am hoping that if the form is blank, it is not necessarily the case that anything of particular security interest was being disclosed, and it is just a process issue, where the Foreign Office did not follow process as it should have and at least put on that form, “Yes, we have done these things.”

I am just trying to do my job, holding the Government to account. Why did Britain employ a man who was a security risk to this really important job? We did so because of the mitigations, but nobody will tell us the mitigations. After all these thousands of bits of paper, and after my poor right hon. Friend the Member for Bristol North West coming to the Chamber 11 times, we still cannot get to the root of it.

[Sir John Hayes]

It would be entirely inappropriate for me, or for any other member of the ISC, to say what we have received, which has now been sent to the police, but given that following an urgent question just before the recess I challenged the Chief Secretary on the issue of mitigations, asking him whether there were mitigations in place and whether they would be made known to us, it would not be unreasonable for a diligent member of the House such as the right hon. Lady to conclude that I would not have asked that question if I had known the answer to it.

[Emily Thornberry]

Well, that is very helpful; I thank the right hon. Gentleman very much.

Let us move on. Is there a record of the decision? When Sir Oliver Robbins appeared before the Committee, and indeed when other people appeared before it, I kept coming back to the same question: “Where is the record of your decision? What was the process that you went through before doing this? Why are there no notes? Why is there no record? How can we hold you to account if you really, genuinely are not making any notes at all?” Given that a decision was made to give Peter Mandelson the job subject to mitigations, where is the record of the decision? Do the police have it? Is it in the papers and I have missed it? I do not think so. Was there never a written record of the decision? Surely someone would have made a record of the action taken—or is that the email? Is that it? Is that the action that they took, or is there something else?

Surely there was a letter written to Peter Mandelson saying, “You have the job, but only if you do x, y and z.” This cannot be dealt with by way of a WhatsApp message or a phone call. This is very serious. This is about the security of our nation, and it should be in a letter. I certainly hope that the reason that I have not seen it is that it exists but the police have it, but I do not know one way or the other.

I know that others will be dealing with this later, and I want to draw my remarks to a close, but the Foreign Affairs Committee has been trying to do its job to the best of its ability to try to ensure that such a mistake does not happen again, and we have been doing that in good faith. It has been difficult. We have been “mandarined”; we have been given partial answers; we have been given nonsense by people believing that it is not for us to know. Well, it is for us to know, and it is for us to know because we are trying to make our Government better, and it is our job as Back Benchers to do that.

[Sir John Hayes]

That is true. Indeed, that might have been reflected in some of the messages that I have suggested to the Department that it might, even at this late stage, make available to our Committee—perhaps that is the most sensible thing given the terms of the Humble Address—and subsequently, in a redacted form, more widely. Even if it were true that because of the pace of the appointment, a full plan could not be drawn up, I find it inconceivable and—I would go as far as to say—unbelievable that there were no communications of any kind associated with the measures referred to by Sir Olly Robbins and Ian Collard.

[Emily Thornberry]

I am grateful to the right hon. Gentleman for giving way—I hope this is helpful. In the written evidence that Collard gave to us, on point 6 in answer to the question, “When was the report received by the department?” he said that they had

“received an email from UKSV at 1.52pm on 29 January informing PST that the report was ready for the FCDO to review.”

That was the date he heard about the developed vetting. The email, which is the nearest thing we have to anything that has any mitigations, is dated 30 January at 10.12 am.

[Sir John Hayes]

The right hon. Lady will know furthermore that Ian Collard, through a letter sent on his behalf to the Foreign Office, told MPs that he had sent an email

“recording the fact of the decision (but not any of the underlying discussions or reasons for doing so) and mitigations”.

She is absolutely right, and when she said earlier that she was unknowing of why this had occurred, I think the whole House would share her view. None of us quite know why on earth that material does not exist or, if it does exist, why it is not being made available.

My fourth point—I am coming to my exciting conclusion; I know you will be pleased to hear that, Madam Deputy Speaker—concerns the declaration of interests form. We know from the first tranche of documents that were relayed to the House that a blank template on declaration of interests for Peter Mandelson to complete was made available, but the completed declaration of interests, from which presumably detailed actions could be derived, has never been made known. I understand that this is another document that may have found its way into the hands of the Metropolitan police. If so, when did that occur, when did the Metropolitan police request it and, again, why? Greater clarity from the Government on the declaration of interests would be most welcome.

Finally, thanks to the learning of the Paymaster General, we were able to speak a little earlier of Gladstone and Disraeli. I carry a picture of Benjamin Disraeli with me at all times. Many people carry pictures of their children or grandchildren; I carry a picture of Disraeli—
