NSPCC "not surprised" at teenagers' porn concerns

The NSPCC's head of sexual abuse programmes says that he is "not surprised" so many young people have concerns about the amount of internet porn they watch.

A survey carried out by the children's charity showed that one in ten 12-13 year olds worry they may be "addicted" to watching explicit material.

But Jon Brown did say he was "concerned" about the findings.
