Security Vetting

Justin Madders Excerpts

Monday 20th April 2026 Commons Chamber

[The Prime Minister]

I do not understand that he had access to STRAP material before he took up his post as ambassador. He did have access after he took up his post, and that is why I have ordered a review of any security concerns that may arise.

[Justin Madders (Ellesmere Port and Bromborough) (Lab)]

We all find it staggering that someone can fail their security vetting and still be appointed to such a sensitive and critical role. It is even more staggering that the Prime Minister was not informed of that failure. I agree with what the Prime Minister said: he did not need to know the details, but he did need to know that Mandelson had failed the security vetting. My question to the Prime Minister is about the detail. If people did not know what the security concerns were of Peter Mandelson, how could any Minister, official or state deal with him on sensitive security issues? I understand that the Prime Minister is doing an inquiry into that, but it is very important that Parliament has oversight of the issue, because I am very concerned that there has been another failure there—the failure to manage our security interests.

[The Prime Minister]

In a case such as this—in relation to such a sensitive post—I do not think it is right that somebody should be appointed at all if the UKSV recommends that clearance is not given. That would be my position.
