Online pornography: Claire Perry MP and Nick Pickles

The Conservative MP who chaired a Parliamentary Inquiry into Online Child Protection said less than half of parents were adding filters to computers and internet-enabled devices to stop children looking at porn.

Claire Perry said an opt-in system, where people chose to get adult material, was a "much safer option."

She debated with Big Brother Watch's Nick Pickles after his Daily Politics film and lawyer Constance Briscoe said it was "of grave concern" that a minister could decide what people could watch online.
