My hon. Friend is absolutely right. It is very disturbing that, when people are in our care and when the state is looking after them, on some occasions, they have been radicalised because of what they have heard in prison either from other prisoners, or on occasion, from visiting imams. We need to sort this situation out. The Justice Secretary has put in place a review. I will look carefully at the report my hon. Friend mentions, but, if anything, we must ensure that people who are already radicalised when they go to prison are de-radicalised rather than made worse.
