Lord Mandelson: Response to Humble Address

Debate between Fleur Anderson and Julian Lewis

Wednesday 3rd June 2026 Commons Chamber

[Sir Julian Lewis]

I am grateful to the hon. Lady for giving way again. She could still develop her case if she talked about parliamentary Committees in general, but I chaired the ISC for four years, and, as I said in an earlier intervention, the ISC has been in existence since 1994. The ISC never leaks. If it did leak, the person who leaked anything would be criminally prosecuted. There is no question, if these vetting documents were shown to the ISC, of its having a chilling effect on anything, because the ISC is hermetically sealed. It does not leak about far more important things than the miserable private life of Peter Mandelson.

[Fleur Anderson]

I thank the right hon. Member for his comment about the ISC. I will continue to take advice from that vetting process: it needs to be even more hermetically sealed. We need to take real care over this. Any over-sharing will have an effect on everyone who is asked to sit down and give the frankest and most private information, and we need to make sure that they are doing that so that their potential risk to our security as a country is very well known. We cannot allow self-censoring because of this process. We do not need those far-reaching unintended consequences.
