My right hon. Friend speaks with great knowledge of this issue, and I welcome the work that he and his Select Committee have done. Like Lucy Powell before him, he is right to raise the issue, which is critical if we are to deal with serious violence and drug misuse properly. The number of exclusions seems to be heading in the wrong direction, and it is important that we look at the links between that and crime. I welcome what my right hon. Friend says and the work that he is doing through the Education Committee.
