PARLIAMENTARY DEBATE
Lord Mandelson Humble Address: Government Response Update - 27 April 2026 (Commons/Commons Chamber)
Debate Detail
As Members will know, the Government published the first tranche of material on 11 March. That first tranche primarily related to the aspects of the motion regarding Peter Mandelson’s appointment and his subsequent dismissal as ambassador, in addition to the details of his severance payment provided to him by the Foreign Office. Following the publication of the first tranche of material, we have been working at pace to lay a second tranche before the House. The House will recognise, given the breadth of the motion, that a very significant number of documents have been found to be in scope and that it is taking time to process them accordingly.
The Cabinet Office team responsible for the Government’s response to the Humble Address has been working through a large quantity of material, working closely with many officials across Whitehall, particularly in the Foreign Office. The team has been seeking to take an approach to sifting and publishing information that allows it to respond to the will of this House thoroughly but expeditiously, and in line with the approach taken by previous Governments in responding to Humble Addresses. This includes co-ordinating a number of requests to Government Departments to identify documents potentially in scope of the Humble Address, particularly electronic communications and the minutes of meetings between individuals and Peter Mandelson. This is the section of the motion that has the broadest scope.
As Members will have seen from the first tranche, the Government cannot publish certain details, such as the names of junior officials, personal information or legally privileged information. Separately, in line with the process agreed by the Intelligence and Security Committee of Parliament, the Government will not publish information that undermines or threatens our country’s national security or international relations. As colleagues will appreciate, both those processes require detailed consideration. The Government are very grateful to the ISC for its constructive engagement in that process, which we recognise has constituted significant additional work on top of its existing responsibilities. As I have set out previously, the Cabinet Office has also been working with the Metropolitan police to avoid prejudicing a live police investigation.
I can confirm that by the end of today, the Cabinet Office will have passed to the ISC all the material it has processed as part of the Humble Address and judged to be prejudicial to national security or international relations. This has amounted to over 300 individual documents. It includes a number that are relevant to the processes of Peter Mandelson’s security vetting, too. As I mentioned earlier, I am very grateful to the ISC for the important role it continues to play in the Humble Address process, and for the speed with which it is processing the documents.
I would like to reassure colleagues that Parliament will receive the second tranche of material as soon as possible following the state opening and the conclusion of the work of the ISC, and I will return to the House at that point. I commend this statement to the House.
I have to ask: where are the documents? The Humble Address was nearly 12 weeks ago. I remind the right hon. Gentleman that on that occasion the House asked for a huge range of things: the due diligence document that was passed to No. 10; the conflict of interest form; the material that the Foreign, Commonwealth and Development Office and the Cabinet Office provided to UK Security Vetting about Peter Mandelson; papers for and minutes of meetings relating to the decision to appoint Lord Mandelson; electronic communications; and so on. Where are they? Since February, the Government have asserted that they are working with urgency and that everything will be available very shortly, that they are working, in that least reassuring of Government phrases, “at pace”, and—today’s favourite—that the information will be available as soon as possible. That is, no doubt, as soon as possible after the local elections.
In the documents that have been released, what we appear to see is either an enormous cover-up or a very significant breakdown in the expected process of government. We have seen nothing from the Prime Minister, nothing from his chief of staff and nothing from Peter Mandelson himself; we have seen no minutes of meetings, no billets-doux, no annotations and no box returns. The official civil service guidance on this matter says explicitly:
“Keep submissions with ministers’ comments. If ministers write on a hard copy, keep the minister’s handwritten comments. Keep correspondence reporting ministers’ responses along with background provided to ministers in the medium in which they were created”.
We have seen none of this. This is either a cover-up or a terrible return to the days of sofa government under Tony Blair.
Simon Case told the Prime Minister that in order to complete due process, there had to be security clearance before he made the appointment, and a conflict of interest declaration had to be made by Peter Mandelson. To date, we have seen none of that information. I am pleased to hear the Chief Secretary to the Prime Minister say that material associated with Mandelson’s vetting is now being handed to the ISC, but where is the conflict of interest form? I hope it is not the case that this is being disguised as personal information of the sort that the right hon. Gentleman said would not be disclosed, and I would be grateful if he could confirm that it is not.
I would also like the Chief Secretary to the Prime Minister to confirm that that declaration of interest form exists. There is no good reason why he cannot tell us whether it does. Indeed, the former Attorney General wrote the other day in the papers that there is no legal reason why the Government cannot tell us which documents are being retained by the Metropolitan police. There should be a catalogue of all documents that exist; even if the House cannot look at them, we should be allowed to know what is out there and what will come to us in due course. The titles of documents will themselves not prejudice a trial.
The Chief Secretary to the Prime Minister has today talked about the non-disclosure of personal information. I ask him again to tell us about the conflict of interest form and whether Peter Mandelson’s personal information is considered to be in scope of that ruling. Will he set out the Government’s precise approach to redactions vis-à-vis the documents that will be given to this House, rather than the ISC? It will be useful to understand his thinking.
On electronic communications, despite this being in the Humble Address on 4 February, I understand from the Cabinet Secretary, who wrote to me over the weekend, that there was no instruction to hand over non-corporate comms until 13 March—about five weeks after the Humble Address. Why this delay? Is the Chief Secretary to the Prime Minister confident that no material was deleted in that five-week period? How can he be sure?
I again ask the right hon. Gentleman to confirm or deny whether the ISC release contains the information about Lord Mandelson’s interests. This is of specific concern to the House, given how Peter Mandelson may have behaved when he was ambassador in Washington and given the meetings that he may have taken the Prime Minister to.
It is time the Government come clean—not on their own terms or to their own timetable, but on the terms set down by the House. Will the right hon. Gentleman finally tell us a hard deadline for when these documents will be handed over?
I can confirm that documents that relate to Peter Mandelson’s security vetting have been passed to the Intelligence and Security Committee today, and that we intend to publish those as part of the second tranche, subject to discussions with the Intelligence and Security Committee.
I was asked specifically about the documents that have been given to the Metropolitan police. I am sure that the hon. Gentleman will appreciate that I have been advised by the Metropolitan police that I am unable to list those documents, and so I will not seek to do so. He asked me about redactions policy; obviously the key redactions policy is in relation to information that the Government consider to be prejudicial to national security or international relations. That goes through the Intelligence and Security Committee for consideration. If there is a disagreement between the Government and the Committee, there is a process of redactions hearings between them to resolve that.
As I mentioned in my statement, other redactions relate merely to information such as the names and contact details of junior officials, in line with established freedom of information policy as it relates to the publication of Humble Addresses.
The Prime Minister promised honesty, integrity and accountability. Instead, we have a tawdry saga of a political ally waved through despite serious security concerns, a senior civil servant forced out, and a Government who have descended into recrimination and infighting rather than dealing with the very serious issues the country faces. Parliament asked for transparency, and the public deserves answers. Every day this drags on, trust in our institutions erodes further.
Even though Lord Mandelson has stepped away from the House of Lords, will the Government bring in formal legislation to revoke his peerage? Will the Chief Secretary confirm whether the Government plan to bring in further legislation for much-needed reform of the other place? The deputy Chair of the Intelligence and Security Committee, the right hon. and learned Member for Kenilworth and Southam (Sir Jeremy Wright), asked in business questions on Thursday about potential further redactions made on grounds other than national security or international relations. Will the Chief Secretary confirm that there have been no redactions in what he said will be sent to the Committee by the end of today?
It has been reported that the Prime Minister is set to whip Labour MPs to oppose his referral to the Privileges Committee. Even Boris Johnson did not block his MPs from voting for scrutiny. Labour MPs must surely be given a free vote and not be forced into feeling like accomplices to a cover up. Will the Chief Secretary confirm whether Labour MPs will be whipped on tomorrow’s vote or not?
I would like to raise two points of concern in what the Minister has said to us this afternoon. The first is about redaction. He has made it clear that the Government intend to redact for reasons beyond the Humble Address exemption related to international relations and national security; he has described that as the names of junior officials, personal information or legally privileged information. On Thursday, I put it to the Leader of the House that the Government document describing their approach to redactions is substantially wider than that. It says:
“It may also be necessary for the government to make further redactions in future publications based on other public interest principles, including”—
but of course not limited to—
“commercially sensitive information.”
Will the Minister please, either today or in writing, explain clearly on what grounds the Government intend to redact these documents? If, as I suspect, some of the grounds on which the Government propose to redact are beyond the scope of the Humble Address, will he confirm that the Government must return to this House and seek consent so to do?
With your indulgence, Madam Deputy Speaker, my final point is also about redaction. The Minister has said in his statement that the Government will not publish information that undermines or threatens our country’s national security or international relations. As he knows, in accordance with the process agreed, it will be for the Intelligence and Security Committee to determine those questions, not the Government—won’t it?
The right hon. and learned Gentleman asked me about redactions policy. I refer him to my earlier answer, but he did ask me some specific questions; I commit to seeking further advice on those and returning to the Dispatch Box. I hope that he and the House know that my intention, from the beginning of when I was asked to do this process, has been to ensure proper transparency with Parliament, which I and the Government take very seriously. If there is any suggestion otherwise, I will answer questions about that here at the Dispatch Box.
The right hon. and learned Gentleman’s second question has fallen out of my mind.
“in line with the process agreed by the Intelligence and Security Committee, the Government will not publish information that undermines or threatens our country’s national security or international relations.”
That sentence is correct, but it implies that this is a Government process that the ISC has acceded to, and that is not quite right. Rather, the Government propose redactions and the ISC directs that redactions be made on the basis that full publication would be prejudicial to national security or international relations. This matters because we want to maintain trust in the Intelligence and Security Committee, of which I am a member. Does the Chief Secretary accept that the Government propose redactions and that the ISC considers them and directs which ones should be made?
Can I follow up on the questions around mobile phones? Ministers will be asked whether they have any communications left on their personal phones. Are they also being asked to tell you, and will we be told, if those messages have disappeared because they have disappearing messages on their phones?
“To ask the Prime Minister who first suggested to him that Peter Mandelson should be appointed as Ambassador to the United States.”
It was accepted and published as such by the Table Office. Subsequently, it has been transferred to the Cabinet Office, for which he has responsibility. It is due to be answered tomorrow. Will the Minister give the answer to that question tomorrow, on time and substantively?
“the Government will not publish information that undermines or threatens our country’s national security or international relations.”
My question is: in whose judgment? Ultimately, is that the judgment of an official or of a Minister? If it is that of a Minister, which one?
“That was a routine meeting in the course of a visit I was on in the US.”—[Official Report, 20 April 2026; Vol. 784, c. 62.]
Does the Minister agree that that was a routine meeting, and if so, where is the record of it, as required by the ministerial code?
