I very much agree with my right hon. Friend. Much work has been done when the UK has suffered some terrible terrorist attacks, and the Government have been required to consider sensibly what more can be done to help us to understand what motivates individuals either to commit acts of terrorism here or to go and join foreign groups abroad.
My right hon. Friend rightly talked about communities and community relations. It should be borne in mind that many members of the British Muslim community do not want foreign terrorist fighters to return to this country, because they fear both the precedent that that will set for future potential foreign fighters and the radicalism of vulnerable young British Muslims by those returning foreign fighters.
