That is an extremely important and very good question. It is all very well trying to divert people away from the path of radicalisation, and we do what we can there, but one of the most difficult things is to reverse radicalisation once it has taken place, as I think the hon. Gentleman understands very well. However, we have a communications cell, as he knows, and we are working on it. We have all sorts of means to try to do these things, but the most important thing is to prevent people from being radicalised in the first place.
