Prevention and Suppression of Terrorism

As a former Home Secretary, my right hon. Friend is obviously aware of the gap that we are trying to plug. He has made exactly the point that I tried to make to the hon. Member for Gainsborough (Mr. Leigh). If we do not use this system, what do we put in its place? How do we plug that gap? I should also point out that we have tightened the system, and no one has absconded since June 2007.
