I am not aware of being present at any illegal raves, and I am not sure if the hon. Gentleman has been to any either.
The issue of illegal raves is important; they cause considerable disquiet, distress and law-breaking in many areas of the country, including the hon. Gentleman's constituency. ACPO has set up a sub-group to look at the issue, and one thing it might consider is whether to take on board the central recording of illegal raves—a point made by the hon. Gentleman. I also point out to him that there are considerable powers available to the police under section 63 of the Criminal Justice and Public Order Act 1994, which was amended by the Anti-social Behaviour Act 2003, to prevent raves from taking place, and to deal with them if they come to pass. I hope that that gives some reassurance to the hon. Gentleman.
