I updated the House last Wednesday on the Government’s response to the Humble Address motion of 4 February, after the first tranche of documents were laid in both Houses in response to that motion. The Government have been clear that they are committed to publishing all documents relevant to the Humble Address, and that further material will be published in due course as officials work through its full scope.
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.
