Lord Mandelson: Response to Humble Address

Nusrat Ghani Excerpts

Wednesday 3rd June 2026 Commons Chamber

[Alex Burghart]

My right hon. Friend is right. The Chief Secretary to the Prime Minister will have heard his remarks, and I hope he will respond to them.

Further to what my right hon. Friend said, the Humble Address was in February, but it was not until March that the Government asked Peter Mandelson for his phone, and Peter Mandelson then refused. As I and other Members said on Monday, the Government should seek to go after Peter Mandelson’s exit payment if he denies co-operation with the Humble Address. It is totally unacceptable that the House should be denied this critical information. We have some information that is retained, some information that appears to have been destroyed and some information that appears to have gone missing.

I wish to turn to some remarks that the Chief Secretary to the Prime Minister made on Monday about his own messages, as he brought them up. I think that will be a useful case study. The Chief Secretary to the Prime Minister said:

“I do recall having some limited exchanges with Peter Mandelson over WhatsApp, including those I have already discussed…but these conversations did not involve transacting Government business and were in line with official guidance on the use of non-corporate communications channels at the time.”—[Official Report, 1 June 2026; Vol. 786, c. 853.]

That is all well and good, but who decided that those messages fell into that category? Did the right hon. Gentleman decide that himself? Did he show them to officials, who then decided? Did he show them to the police? Who made the decision? Again, we must ask these questions of all Ministers who were asked to disclose information. Where is it that people have self-edited? Where is it that people have had auto-deletion on their phones? Where is it that people have refused to hand things over? We deserve to know.

Something that I believe is missing throughout the three volumes we received on Monday is photos, videos, voice notes and, more significantly, attachments. I would be very interested to hear the Minister’s explanation for the Government’s approach to those types of document. Let me draw attention in particular to document 33, from 15 September 2025. The email explicitly refers to an attachment, which is pertinent to the subject of the Humble Address, but that document is not available. I could have been led to believe that that document may have been retained by the police, were it not for the fact that all attachments seem to be missing and all photos, voicemails and videos are also missing. I cannot help but feel that it has accidentally fallen out of the full disclosure. May we have some clarity on that?

Let me turn to Peter Mandelson’s declarations of interest, which are one of the most important classes of document; they are perhaps the most important class of document that we are yet to see. We now know that something definitely does exist—first, because the Chief Secretary to the Prime Minister told us on Monday, and secondly, because there are references to a back-and-forth about Mandelson’s contacts in the release. Mandelson pushed back on a number of occasions, saying, “I know a lot of foreign people. I have a lot of contacts. I cannot be expected to disclose everything. There was a suggestion from one official not to worry about it too much, just to get on with it and give them a list.”

We appear also to be seeing an absence of documents, such as the mitigations that the Chair of the Foreign Affairs Committee, the right hon. Member for Islington South and Finsbury, referred to—Collard’s document. If we add it all together—the absence of the declaration of interests, the absence of the mitigations designed perhaps to handle Mandelson’s relationships with his business contacts when in office, the fact that the documents of certain members of the Cabinet are entirely absent, and the business interests that we know Mandelson had—I think we can reasonably hypothesise about what the police are looking at. That would be—this is speculation—an abuse of his position in Washington to support the interests of his business relations. It is very unfortunate that we will not see that information for some time, because it goes to the heart of one of the problems with the appointment of Mandelson in the first place. [Interruption.] I think Madam Deputy Speaker is encouraging me to wind up, so that I will do. [Hon. Members: “Hear, hear!”] I can understand why the Government do not want me to ask them any more questions.

In conclusion, there are a number of things that we need of the Government. Most importantly, we need a slightly fresh approach to disclosure where we are told a bit more about what the police have: how many documents in each category, how many WhatsApps and emails of the Prime Minister, Peter Mandelson and Morgan McSweeney, and so on. It is important that the House understands where things have gone missing and can start to put that picture together in its head. I say to the Chair of the Foreign Affairs Committee that, once the police investigations are complete, it would be interesting for the police officers involved to come before the Select Committee—it may fall to another Committee as well—to discuss what their approach has been and why, and what lessons might be learned for future disclosures to Parliament.

I end by turning, rather unfortunately, to the last speech that Peter Mandelson ever made in the Lords, where he said:

“I feel very deeply that there will not be anything like the systematic undermining of the Civil Service that we have seen in recent years…when government policy was conducted by private WhatsApp, rather than on properly considered Civil Service advice.”—[Official Report, House of Lords, 28 November 2024; Vol. 841, c. 830.]

This scandal has taken the jobs of the ambassador to Washington, of the Prime Minister’s chief of staff, of the Cabinet Secretary and of the chief official in the Foreign Office—and, ultimately, it will take the job of the Prime Minister.

[Madam Deputy Speaker (Ms Nusrat Ghani)]

I will now announce the result of today’s deferred division on the draft Agriculture (Delinked Payments) (Reductions) (England) Regulations 2026. The Ayes were 302 and the Noes were 153, so the Ayes have it.

I call the Chair of the Foreign Affairs Committee.

[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.

[Madam Deputy Speaker (Ms Nusrat Ghani)]

I call the Liberal Democrat spokesperson.

[Sir John Hayes (South Holland and The Deepings) (Con)]

This House stands tall when those across it find common cause in speaking for the people. Our authority is derived from just that. There is immense wisdom present in the House today, and probably even greater wisdom that is not present, but that is not the essence of the root of our authority which is derived from our election, and when the House finds its feet in the way personified by the speech of the hon. Member for Pontypridd (Alex Davies-Jones), the message broadcast from this place more broadly is that MPs do not merely dance to the tune composed and conducted by the Treasury Bench, or indeed the Opposition Front Bench, but are capable of making judgments of the kind that she epitomised in making her contribution earlier.

I have been part of this process. I will not say that I have sweated blood, but I have certainly spent a great deal of time on it, as has my right hon. and learned Friend the Member for Kenilworth and Southam (Sir Jeremy Wright). Over the past weeks, I have seen more of my fellow members of the Intelligence and Security Committee than I have of my own family, as we have trawled through immense numbers of documents.

Following that process, I want to make five points. The first is that the Humble Address—there is a debate to be had about the appropriateness of Humble Addresses; we have rehearsed parts of that debate today—was absolutely explicit in its instructions to the ISC. It empowered the ISC in a unique and unprecedented way to examine those documents concerning international relations and national security pertaining to the appointment of Peter Mandelson as the ambassador in America. I do not accept the arguments about the withdrawal of documents and about precedent, because this particular Humble Address empowered the ISC in an unprecedented way.

It did so on 4 February, in expansive terms. There is a case to be made that the Humble Address was too permissive, but that is not for us to debate now, for that was the debate that took place then. For example, it talks about all “electronic communications”, yet we have seen nothing of the videos, recorded messages or other kinds of electronic communications that clearly might be salient to our consideration of whether Peter Mandelson should have been appointed at all, and why he was appointed.

The Humble Address gave the ISC that instruction, and so it is important to make it crystal clear that the ISC is a Committee of Parliament with unique and special legal powers, and those legal powers extend beyond any other Committee of the House and enable the Committee to look at the most sensitive matters of all, such as STRAP documents. I would argue that such documents are as sensitive as, and in many cases more so than, anything that we might have been offered as a result of the Humble Address providing that instruction to us, yet the Government took the decision not to make available to the ISC the vetting file associated with Peter Mandelson. The argument used was that if they did so, it would have a chilling effect on the whole vetting process.

I regard that as specious because it confuses scrutiny with disclosure. The ISC was never going to disclose any of that material—a point made by its former Chairman, my right hon. Friend the Member for New Forest East (Sir Julian Lewis). It was a matter for the Government to have faith in the ISC—as the House clearly did—or at least for the Government to reflect the faith of the House in providing all the relevant material to the ISC. But let us leave that to one side.

The Minister might want to come back to this, because my right hon. and learned Friend the Member for Kenilworth and Southam, who sits on the ISC with me—indeed, he is the deputy Chairman of that Committee—came to the House with an urgent question, explicitly requesting that the Government return to the subject of the Humble Address to see whether they wished to amend it, to legitimise their decision not to provide that information. The Government chose not to do that. In other words, they chose not to ask the House for consent. That is a highly questionable decision and, frankly, I think the Government will come to regret not coming back to obtain that consent.

Let us move on to my second point. I will not say too much about this, but it is now known—it is in the public domain—that the ISC did receive a summary document. Indeed, some of that summary document has found its way into the public realm by means of a national newspaper, the Manchester Guardian, which clearly had access to information. We heard earlier that there may be an inquiry into how that information found its way into the press, but we were told that that information would not be available in the second tranche of information, even in redacted form, because it was required by the police. However, we do not know when the police made that inquiry or when they decided that the information was vital to their investigations, and we have been given no rationale as to why they might have come to that decision so late in the process. Had they made the decision earlier, we would have saved a lot of time, and the expectation that we might have seen more about vetting would not have been fixed in the minds of Members of this House.

It is important that the Chief Secretary to the Prime Minister is crystal clear about when that request from the Metropolitan police was made, and it would be helpful if he could give us some indication of why. Clearly he could not compromise the investigation or any subsequent legal action, but giving the House some indication of when and why the police changed their tune, as it were, in respect of the summary of the vetting file would be highly desirable.

Let me move on to my third point, which concerns mitigation. I said that there were five points, and I know you are counting them, Madam Deputy Speaker.

[Madam Deputy Speaker (Ms Nusrat Ghani)]

I am.

[Sir John Hayes]

Indeed, you will chastise me if I do not stick to my chronology precisely, Madam Deputy Speaker.

As the Chair of the Foreign Affairs Committee, the right hon. Member for Islington South and Finsbury (Emily Thornberry) said, there is some confusion about the character of mitigation. We certainly know that nothing has been provided in respect of mitigation or about the reaction to the flags about Mandelson’s associations with senior figures in foreign states or his personal circumstances, yet Sir Oliver Robbins gave evidence to the Foreign Affairs Committee in April—its Chair has made this clear—in which he said that clearance could be approved if

“risks identified as of highest concern…could be managed and/or mitigated.”

Such mitigations were meant to have been noted in an email from Ian Collard, the Foreign Office head of security, noting the decision to grant Mandelson’s clearance. According to Sir Oliver Robbins, that email recorded

“the ways in which we would manage”

Mandelson’s clearance and “the mitigations”. Sir Oliver Robbins’s claim was supported by the top official in charge of gathering the Humble Address material, Cat Little. She told MPs that she had seen an email that

“sets out the decision to grant DV and some mitigations.”

There was certainly a stated need to manage the risks associated with Peter Mandelson’s appointment and an acknowledgment that that might be done through some process of mitigation, but we have heard no more. It may be that no detailed mitigation plan was drawn up. It is perfectly possible that that might have happened, for the very reason that these risks were so great that they could not have been mitigated. However, even if that were the case, surely there would have been box notes or communications in emails making all that clear between the Foreign Office and the Cabinet Office, between UKSV and the Cabinet Office, and between Ministers and officials, yet we have seen nothing.

[Sir John Hayes]

I would not recommend it.

[Madam Deputy Speaker]

Order. Regardless of whichever picture Mr Martin would wish to carry, it is always decent for Members to ensure that they are in the Chamber long enough before intervening on someone who is giving a speech.

[Sir John Hayes]

I will say no more except this: Disraeli said that circumstances are beyond our control, but we all have control of our conduct. Of course it is true that the context in which the appointment of Peter Mandelson was made was beyond the control of the Chief Secretary to the Prime Minister who is responding to the debate, but the conduct of the Government, as described by my right hon. and learned Friend the Member for Kenilworth and Southam, is a matter for which he and other members of the Treasury Bench are answerable. The conduct of this affair seems to me to be, at best, highly questionable and, at worst, something much more serious.

I simply say to the Chief Secretary to the Prime Minister: there is still a chance to put to rights some of these wrongs in what happens next. Some of the questions posed from across the House, as it found its feet earlier today, can and still should be answered. We will not get the full detail until the Metropolitan police have conducted their own inquiries and I understand that, but there is much that can be done to provide further explanation about the things we have not seen and why.
