I do not know which group was responsible for that terrorist attack, but I was using it as an example of the fact that that was happening all over the world and could happen here. We have to guard against the dangers of terrorism. It is a very serious matter, and I am sure that this Minister and this Government take it very seriously indeed.

I have just three or four points to make, one of which Mr. Leigh has reminded me about. It is the fact that the Home Secretary has not had to use the powers in the legislation to impose an urgent order. I wonder whether that is because things are getting better, so there is no need for the Home Secretary to use those powers. The powers are reviewable by the courts within seven days of the order being imposed. When the Minister winds up the debate, perhaps he will explain whether what I have referred to is a sign that matters are improving in the fight against terrorism.
