Counter-Terrorism and Border Security Bill

I hear what the hon. Gentleman says about Prevent, and welcome his warm support for its principles. I am glad that he has been to see its programmes, as I did when I was Minister for Security. He makes a useful point about oversight of Prevent and about measuring the implementation of the Prevent duty. He will remember that we introduced that duty when I was the Minister. The duty affects a wide range of organisations, but the evidence suggests that its effectiveness varies across them. It would seem to be useful to take a look at that, but I would not call that a wholesale review; rather it is measuring its effect.
