National Security Bill

My right hon. Friend is right that this is an important step. In particular, he is right about the foreign influence registration scheme, which has long been called for, including by the Intelligence and Security Committee, of which I am a member. He will also know that, because we have yet to discuss that in any detail, there may be confusion about the primary and secondary tiers—in other words, those things that are designated as being of more profound importance than these other things. Would it be helpful if he were to write to the ISC, setting out how he thinks they would work in practice, given that we understand that the secondary tier will be introduced by secondary legislation?
