I absolutely agree with my right hon. and learned Friend. In a sense, he refers to the fact that a number of plots have been disrupted in recent years, and it is easy to forget that when the threat level is at severe it means that an attack is highly likely. We live in a free and open country, we live in a democracy, and as he says it is not possible to ensure that we can prevent the possibility of any attack, but we can work as hard as our security services and police do precisely to try to prevent attacks. They have worked hard and have been doing a good job, and they continue to do a good job, in keeping us safe and will do so into the future.
If we are to defeat this evil, my right hon. and learned Friend is right that we will defeat it through our democracy and our values. We must defeat, of course, the terrible ideology that leads people to conduct these horrific attacks.
