Sir Julian Lewis: Does the Minister share my concern that, irrespective of the personal motivation of the perpetrator, the circumstances by which he came into this country send a signal to those ideological movements abroad that wish us harm that there is a very easy back door by which they can infiltrate this country? If an operation of that sort is mounted in the future, what sort of violent response will there be to a spectacular terrorist attack that could and should have been prevented by secure borders?

[The Minister for Security (Dan Jarvis): As always, the right hon. Gentleman raises a very thoughtful series of questions. I know he will understand that I am not going to get into the detail of the potential motivations of the alleged offender in the particular circumstances, but his general challenge is the right one. It is the job of this Government, and of any Government, to ensure that the United Kingdom is the hardest possible target for our adversaries and for those who would do us harm.

The right hon. Gentleman knows, from his previous service on the Intelligence and Security Committee, a lot about the nature and range of threats that we face as a country. I hope he also knows that this Government, like the last Government, do everything they possibly can to make sure that where there are particular points of vulnerability, we are bearing down on them, and that we have in place the right capabilities and resources to keep the public safe. There is no more important duty of any Government than being able to do that, and that is what I as the Security Minister and my colleagues across Government spend each hour of every day making sure that we do.]
