I back the thought of the hon. Member for Romsey, who has queried the clause. I raised the matter on Second Reading. It is well known that many paedophiles have written material of a nature that would shock most, if not all, of the people on the Committee. Paedophiles use such material to stimulate themselves and others and they spread it. I accept that that is an exceptionally difficult area in which to apply the law and I suspect that the Minister will have extreme difficulty in dealing with it. That was the response before.
