PARLIAMENTARY DEBATE
Lord Mandelson: Government Response to Humble Address - 19 May 2026 (Commons/Commons Chamber)
Debate Detail
The Government confirmed before Prorogation that we had referred more than 300 documents to the Intelligence and Security Committee. At the time, that represented all the documents in scope of the motion where the Government believed that publication would be prejudicial to UK national security or international relations. The Government have repeatedly assessed all the documents we have collected to make sure that all of those that need to be referred to the ISC are referred to the Committee. As part of this quality control process, the Government identified a small number of further documents that we felt should be reviewed by the ISC, and we immediately submitted those documents to the Committee. As Friday’s statement from the Committee set out, it has now considered all those documents.
As I have previously said to the House, the Government will be publishing a second tranche of material. This is currently being finalised and will be one of the largest Government publications ever laid in this House. That is reflective of the breadth of the motion, and also the Government’s commitment to transparency in responding to it. It constitutes a very significant disclosure exercise involving sensitive material from across Government. The Government have taken seriously our obligations to comply with the Humble Address in full, while also upholding other public interest issues, such as our duty of care to junior staff. The Government have carried out this work according to a robust process, with assurance from an independent KC.
Given that the House is due to rise on Thursday, and given the length of the publication, the second tranche will now be published after Whitsun recess to give the House sufficient time to review the material and to be able to ask me and the Government questions. It could have been published this Thursday, but I felt that the House would have deemed that to be inappropriate, given that it will be such a significant publication. [Interruption.] To refer back to my previous comments, this will be the largest publication—other than, I think, the Chilcot inquiry report—ever published to the House.
When the Government publish the second tranche of documents, we will also publish a methodology confirming the process we have followed, and the basis on which content has been redacted will be clear from the published information. The targeted redactions made to the material, beyond those relevant to national security or international relations, have been made in line with clear precedent set by previous Administrations in responding to Humble Addresses.
As I set out to the House on 23 February, and again when we published the first tranche of material on 11 March, we have taken the normal approach to redacting junior officials’ names, contact details such as telephone numbers and email addresses, the personal data of third parties where that is not in scope of the motion, and, where relevant, legal professional privilege. That has been done using the principles set out in the Freedom of Information Act 2000, and in line with the ministerial code and the resolutions on ministerial accountability passed by both Houses in 1997. Those resolutions state:
“Ministers should be as open as possible with Parliament, refusing to provide information only when disclosure would not be in the public interest, which should be decided in accordance with relevant statute”.
I am sure that Members across the House will recognise that there is no public interest in the Government publishing the names and contact details of junior officials or their telephone numbers.
As the Minister says, the Government issued a list of further grounds on which they intended to redact along with the first tranche of documents that they published. Those grounds include email addresses, phone numbers and what is described as personal data. There is no mechanism for the House to confirm that those redactions are limited only to what is necessary, but I want to ask the Minister about material that the Government intend to withhold for yet further reasons, such as commercial confidentiality or to protect the monarch. The Government also intend to withhold some documents related to vetting in their entirety.
I should make it clear that my Committee has considerable sympathy with the substantive arguments that the Government may make for withholding information beyond that currently justified in the Humble Address. There are, for example, valid concerns about the disclosure of information given in a vetting process inhibiting future subjects of vetting, or those who are asked about them, from being as open and forthcoming as they need to be for vetting to be effective. However, we cannot accept that the Government are entitled to ignore, or unilaterally alter, the terms of the Humble Address.
Does the Minister accept that if the Government want to argue that the Humble Address is too broad as drafted and needs to be refined, they must come to the House and make that argument, and secure the House’s consent to any alteration? Does he further accept that without doing so, when the next set of documents is published with information withheld, the Government will not succeed in persuading the House or the wider world that this matter is closed? Finally, does he accept that if the Government took it upon themselves to redact or withhold information contrary to the terms of the Humble Address by which they agreed to be bound in February, that would be an issue not just of process, but of parliamentary sovereignty?
The right hon. and learned Gentleman was, I think, asking me specifically about personal data that was collected as part of the security vetting process. As I think he suggested, the raw data that is collected as part of those investigations—perhaps relating to how much money someone has in a particular account, or with whom that person may have had a personal relationship in the past—would never be published, because if we did so, people would feel unable to answer those questions honestly and frankly in any UK security vetting investigation in the future, which would undermine the very basis of our national security system.
Sadly, this pattern of backsliding fits a pattern of behaviour. The Prime Minister’s chief of staff had to resign over the Mandelson scandal, but apparently he is already back and advising the Prime Minister. We forced the Government to hold an inquiry into the grooming gangs, but then they sabotaged it and dragged their feet for a whole year. We said that it needed to be harder to obtain indefinite leave to remain; the Home Secretary said she would do it, but Labour Back Benchers did not like it, and now it is not in the King’s Speech. Again and again, as soon as attention moves elsewhere, the Government start backsliding.
We now expect the Government to discuss their approach to the Humble Address constructively, and we would welcome such discussions. Let me therefore ask the Minister some questions. Now that the ISC has reviewed all the documents, when will the Government release all the rest of the Mandelson files? The Minister has said “after Whitsun”; when after Whitsun? Will the Government return to the House to ask permission for the redactions that they clearly wish to make which go beyond the scope of the Humble Address? Will the Minister brief Opposition Members, on Privy Council terms, about the broader redactions that the Government clearly wish to make?
Labour Members voted for a cover-up when they voted against referring the Prime Minister to the Privileges Committee over this matter. [Interruption.] They do not like it, but it is true. This House, and the people of this country, deserve better than yet another cover-up.
On the questions the hon. Gentleman has put to me, I have answered them in the statement and in my answer to the deputy Chair of the Intelligence and Security Committee, and I refer him to my previous answers.
It is very important that the public know and understand that we are learning from the mistakes that were clearly made, and we cannot know that lessons have been learned unless the documents are checked. My Committee and the ISC are trying our best to get to the truth, and we are having obstacles put in our way. For that reason, I believe that the ISC should be allowed to look at the file, with proper redactions, to understand how mitigations could be put in place to make us safe when it came to the appointment of Peter Mandelson.
Given that documents on Andrew Mountbatten-Windsor’s trade envoy role are also due to be laid before this House shortly, will the Minister confirm that he will personally ensure that those are produced without redaction, too?
On the hon. Lady’s question about the motion in relation to Andrew Mountbatten-Windsor, that Humble Address is being administered by the Department for Business and Trade, and I understand the document is due to be published very shortly.
“Humble Address does not allow for documents to be withheld from Parliament, only for redactions to be made where the ISC has agreed to them.”
Last week, we were obliged to issue a further statement saying that it had come to our attention that documents were being withheld from the ISC. The right hon. Gentleman may feel that that is justified, but the Humble Address does not permit it. The point is that he is confusing scrutiny with disclosure. The ISC is well used to making judgments about what is made public. That is why the House chose the ISC as the mechanism to deal with these matters. Will the right hon. Gentleman confirm that, in line with the Humble Address, all material will be submitted to the ISC? In particular, will he confirm that there was no document or any communication—emails and so on—related to the mitigation of any risks associated with Peter Mandelson’s appointment?
“Where the current Tory government has muddied the waters of transparency…I want to make it easier to hold government to account.”
He said that a Labour Government must
“play its role in restoring honesty, decency and transparency in public life”—
and yet here we are. Does the Minister agree that after all the redacting of messages, it is not only the Labour party that is being damaged, but democracy itself?
“That this House finds Ministers in contempt for their failure to comply with the requirements of the motion for return passed on 13 November 2018”. —[Official Report, 4 December 2018; Vol. 650, c. 668.]
That motion was passed by this House.
We have just debated an area where the Government may potentially be in contempt of the House; indeed, the obfuscation we have heard looks like that. It is important that the House and the Government know that there is precedent in this area. I give notice that if, after we have received the next tranche of documents, the Humble Address has not been met in full, or if we have not been told the truth, the whole truth and nothing but the truth, I will seek to table such a motion.
