PARLIAMENTARY DEBATE
Lord Mandelson: Response to Humble Address - 16 March 2026 (Commons/Commons Chamber)
Debate Detail
The first tranche, as the title of the document made clear, represented,
“Part of a Return to an Address of the Honourable the House of Commons dated 4 February 2026”.
It responded directly to a number of specific elements contained in that motion, namely papers relating to Lord Mandelson’s appointment as His Majesty’s ambassador and the discussions that subsequently led to his dismissal. As the Government have said previously, there are specific documents that we would like to disclose but which the Metropolitan police has asked us not to in order to avoid prejudicing the ongoing criminal investigation into Peter Mandelson. The Government have agreed to that request. We will publish those documents in the future once the Metropolitan police has confirmed that it will no longer prejudice its investigation.
As a consequence of that, and as I set out to the House on 11 March, the Government have therefore taken the extraordinary step, as agreed with Mr Speaker, of briefing the Chair of the Public Administration and Constitutional Affairs Committee, the hon. Member for North Dorset (Simon Hoare), on terms agreed by the Metropolitan police to ensure that there is as much transparency to the House as possible.
As the House understands, the Government must carefully assess the risk of prejudicing UK national security or international relations posed by the release of any official documents. Again, this process is subject to parliamentary oversight. Any such material will be and is in the process of being referred to the Intelligence and Security Committee of Parliament. I thank the Committee for its assistance and can confirm that this process was also followed regarding the first tranche of material published last week. Outside of this arrangement, the important and well-established constitutional principle that national security and international relations judgments are ultimately for the Government has not changed.
We are continuing the disclosure process for other documents across Government within the scope of the address. Given the breadth of the motion agreed by the House and the large number of materials and Departments involved, this process will take time and necessarily requires careful consideration. Where relevant documents are held, they are being prepared for release through an established process, including the appropriate checks relating to national security, international relations, legal privilege and the protection of personal data.
The Government have acknowledged that the documents published reveal that the appointment process fell short of what is required. As previously set out, the independent adviser looked last week at the process and concluded that he saw no grounds for the investigation that the shadow Chancellor of the Duchy of Lancaster, the hon. Member for Brentwood and Ongar (Alex Burghart), has requested, but as the Prime Minister set out this morning, the inherited process itself was not strong enough. That is why the Prime Minister has already strengthened the process and is committed to strengthening it further in the future. This forms part of wider changes that the Government are bringing forward to improve the system, including a review by the Ethics and Integrity Commission relating to financial disclosures, transparency around lobbying, and the business appointment rules, alongside a review of the national security vetting system.
As I have said, and I know Members across the House will agree, Jeffrey Epstein was a disgusting individual, and Peter Mandelson’s decision to put their relationship before his victims and the vulnerable was reprehensible. That is why there is cross-party consensus across the House for transparency and accountability and why the Government are committed to publishing all material relevant to the Humble Address. I will continue to keep the House updated as a matter of priority, as I have done to date, and I commend this statement to the House.
Last Wednesday, the Chief Secretary to the Prime Minister said:
“All the documents that are available in relation to Peter Mandelson’s appointment and dismissal are published…today, subject to those that have been held back by the Metropolitan police.”—[Official Report, 11 March 2026; Vol. 782, c. 371.]
But many, many documents are missing. I have detailed 56 documents in a letter that I sent him. To give a few examples, there is no prime ministerial readout on the advice that the Prime Minister received. This is a breach of protocol. A prime ministerial decision, even if made orally, should be formally recorded. Where is that record? It starts to stink of the sofa government that we had under Tony Blair.
There are no minutes of any meeting at which this appointment was discussed, by anyone, at any time. Were there really no meetings about this? Most suspiciously of all, we have no material from the Prime Minister, from his chief of staff or from Peter Mandelson: no box returns, no emails, no forms, no WhatsApps—nothing. It is as though their fingerprints have been forensically removed.
To narrow this down, on 11 November 2024 the Cabinet Secretary said that if the Prime Minister wanted to make a political appointment, the civil service would
“develop a plan for…the necessary security clearances and do due diligence on any potential Conflicts of Interest”.
That was the process, so let me ask the Chief Secretary two very specific questions. First, did Peter Mandelson receive security clearance, and if so, on what date? There was no such document in the release. Secondly, did Peter Mandelson make a full declaration of his interests? Again, there was no such document in the release.
I remind the Chief Secretary that noting the existence of a document does not prejudice an investigation in any way. The Government have already told us about one document that they are holding back at the request of the Met police; they are more than able to tell us about others. It is time for the Government to level with us. What is missing, and why?
The shadow Minister made reference to questions about WhatsApps and other messages. I can confirm that those types of documents will be subject to a further tranche being published in due course. He also asked me about security clearance for Peter Mandelson. I refer him to the answer I gave last week in respect of that question, and to further comments from the Foreign Office.
As well as confirming that Mandelson’s ongoing relationship with a convicted sexual predator was known, the files also revealed that he was given top-level briefings before his vetting was finished—a vetting process that clearly failed by any measure. Trust in politics is already stretched thin, and I am sure that everyone in this House wants to see it restored. If the worst fears of this sorry saga are found to be true, that trust will take another body blow, boosting only the populists on the left and the right.
I therefore ask the Minister, if the Prime Minister really wants to rebuild trust and ensure that the proper procedures are always followed, will he commit to taking up Lib Dem calls to make the ministerial code binding in law, and will he refer himself to the independent ethics adviser to determine whether, in the course of this long, sorry saga, he has breached the code or not?
I refer the hon. Member to the letter from the independent adviser, which came out on Friday of last week and concluded that there were no grounds for an investigation into the Prime Minister’s conduct, because the process that the Government inherited for these types of appointments had been followed appropriately. The process itself, as the Prime Minister said again this morning, is clearly not sufficient, which is why it needs to be changed for the future.
“In criminal matters, proceedings are active when a charge has been brought”.
That is the balance between justice and democracy. Given that Mr Mandelson has not been charged, this matter does not fall under the sub judice rule, and he might not be charged for a year or more, if ever. There appears to be no other statutory bar to the Government releasing information: the Police and Criminal Evidence Act 1984 does not apply; the Freedom of Information Act 2000 does not apply; and the Contempt of Court Act 1981 does not apply because section 5 of that Act excludes public debate of matters of public interest. Given the lack of statutory bars preventing the Government from acting, will the right hon. Gentleman release that documentation?
“to avoid…unwelcome publicity or reputational damage”,
Foreign Office advice to the Prime Minister said:
“Given the reputational impact for HMG, a modest settlement as proposed is the recommended course of action.”
Does the Minister maintain that no rules were broken with Mandelson’s payoff?
We on the Labour Benches are furious with Peter Mandelson; he hoodwinked left, right and centre, requiring the Prime Minister to ring him up in the embassy in the middle of the night to fire him. The Prime Minister has said that if he had known then what is now known, he would not have appointed him.
There is a criminal investigation under way that we cannot cut across, and there are critical pieces of information that have not yet been disclosed, including the follow-up questions and Peter Mandelson’s answers to them. Will the Chief Secretary to the Prime Minister outline when we might hear about the next steps and the release of those questions and answers? I think we should be reserving judgment until we see the totality of the evidence; as politicians, we are here to be led by the evidence.
“That was not the rationale. The documents will speak for themselves.”—[Official Report, 11 March 2026; Vol. 782, c. 367.]
Of course, the documents do speak for themselves. They say that part of the business case for the payout—which the Minister was aware of, because it was sent to him—was that
“Given the reputational impact for HMG, a modest settlement as proposed is the recommended course of action”.
They also say that
“the individual has a high profile which could give rise to reputational damage to the FCDO and HMG were a court or tribunal claim to be pursued”,
which is exactly what I suggested based on what was in the papers, but which the Minister denied was part of the reasoning. Does he want to apologise for inadvertently misleading the House, and does he agree that those papers show that the Government broke Treasury rules on how such payments should be made?
“If I knew then what I know now, he would never have been anywhere near Government.”—[Official Report, 4 February 2026; Vol. 780, c. 258.]
What additional information did the Prime Minister get to come to that conclusion?
“be as open as possible with Parliament”
and maintain high standards of accountability. That is not just in what they say, but what they fail to say. I know that you do not enforce the ministerial code, Madam Deputy Speaker, but would you expect a Minister who has misled the House by omission to return to the House to correct the record?
