Lord Mandelson: Government Response to Humble Address Motion

(Urgent Question): To ask the Chief Secretary to the Prime Minister to make a statement on the Government’s response to the Humble Address agreed by this House on 4 February 2026, including on progress made, timescales for compliance and the Government’s approach to any material it proposes to withhold or delay.

Last week, the House made a Humble Address to His Majesty for the Government to disclose material surrounding the appointment of Peter Mandelson as ambassador to the United States of America. On Monday, my right hon. Friend the Chief Secretary to the Prime Minister updated the House on further action that the Government are taking.

My right hon. Friend confirmed that the Government will bring forward legislation to ensure that peerages can be removed from disgraced peers, and that Peter Mandelson will be removed from the list of Privy Counsellors. He also explained how we have changed the process for relevant direct ministerial appointments, including politically appointed diplomatic roles. He also set out other areas where we recognise the need to go further, including tightening transparency and lobbying.

In that statement, my right hon. Friend also set out how the Government are responding to the Humble Address motion, and I am pleased to provide a further update to the House today. The Government will comply fully and publish documents as soon as possible. As I said in the House last week, we welcome both the principle and content of that motion, and we will deliver on it as soon as we can. As such, Departments have been instructed to retain any material that may be relevant, and work is under way to identify documents that fall within the scope of the motion. We will do so as soon as possible when the House returns from recess.

In line with the motion passed by this House, where the Government consider that documents may be prejudicial to UK national security or international relations, the Cabinet Office will refer that material to the independent Intelligence and Security Committee. The Prime Minister has written to the ISC, and senior officials have met the Committee to discuss what it requires in order to fulfil that role. As I said in the House last week, full resources will be made available to ensure that process happens, and we will work with the Committee to explain the Cabinet Office’s process for providing material relating to national security or international relations. The Government are very grateful to the ISC for its work, and we commit to full engagement with it to ensure timely and effective release.

The House will also be aware of the statement from the Metropolitan police regarding the ongoing police investigation. That statement made clear that the

“process to decide which documents should ultimately be published remains a matter for…parliament.”

That is absolutely right, and we agree, but as the House would expect, the Government rightly do not wish to release anything that may undermine an ongoing police investigation. As such, we are working with the police as they conduct their inquiries to manage this process. I think that is the right way forward, Mr Speaker, and I hope you and the House agree.

Now that you have brought me into it, I will just say that the Intelligence and Security Committee is private and independent, and therefore I would not like to see that it was blocked from information. It would not affect any police investigation, because that information would not go into the public arena. I just want the House to be aware of that.

I also thank the Minister for coming to the House. To me, on something as important as this a written ministerial statement is not good enough; I think it should have been brought to the House. All sides are interested in it, and it is right that this House should be informed, so I really am pleased. I am sorry that the Minister has got the short straw, but I thank him for being here.

I call the shadow Chancellor of the Duchy of Lancaster.
