Prevention and Suppression of Terrorism

I shall conclude, because my hon. Friend the Member for Hackney, North and Stoke Newington is anxious to speak, and we have known each other for a long time, so we can share the minutes that are available. These are fundamental principles of justice, and people ought to know why they are the subject of control orders. That policy is central to the Government's counter-terrorism strategy, but why have it when the very people whom one has under surveillance abscond? It shows that there is a real problem with the policy.
