Lord Mandelson: Government Response to Humble Address

Jeremy Corbyn Excerpts

Monday 23rd February 2026 Commons Chamber

[Darren Jones]

I believe the documents will show that the Prime Minister was lied to by Peter Mandelson.

[Jeremy Corbyn (Islington North) (Ind)]

It is very clear that the issue has been referred to the Intelligence and Security Committee and that it will look at issues of national security and international relations. I intervened in the debate on this matter; it is possible that the Chief Secretary heard that intervention. I want him to be very clear that in the event of the committee discovering commercial links from Mandelson to any company, including Palantir but not excluding others, they will be pursued and will not be ignored because they do not necessarily impact immediately on the very narrow definition of national security and international relations.

[Darren Jones]

The commission for information from Departments that is taking place has not yet resulted in those documents being shared with the Cabinet Office. If issues need to be pursued further once the documents are shared, we reserve the right to do so.
