Sir Julian Lewis: I have come to this debate without any prior knowledge of what is proposed, so I am making this point as a result of what I have heard so far. Am I right in thinking that what the Minister particularly has in mind is people with dual citizenship who might, for example, have gone abroad to fight for a terrorist organisation, such as ISIS. There would, in such a case, be nothing forbidding us from removing their British citizenship. If they came back, even if they could be convicted of anything at all, they would be imprisoned for only a relatively short time, if at all, and then the security services would probably have to spend many years monitoring them. Is that the sort of scenario the Minister has in mind?

[The Minister for Security (Dan Jarvis): I am always grateful to the right hon. Gentleman. It is. Perhaps he did not hear me make that point earlier, but I specifically said that one of the reasons for the Bill was to prevent someone who is outside the UK, and who poses a risk to our national security, from returning when a further appeal may be upheld by the Home Secretary’s decision. He is right: that is a potential scenario that we have to guard against, and the Bill will enable us to do that, just as Governments could prior to the ruling of the Supreme Court. I hope he finds that reassuring. ... ]
