Online pornography: Nick Pickles on internet filters
The government is considering introducing filters to block adult material as a default for internet customers to help parents stop their children seeing inappropriate material.
But Nick Pickles from Big Brother Watch said this was not the way forward, as they failed in the Netherlands, and Ofcom found they would be "trivial to circumvent".
He said it would be a "very, very dangerous step" to give the government power to decide what people can watch.
