Web porn: Cameron says parents can face 'jungle'

Prime Minister David Cameron has been meeting internet industry representatives to discuss how they can stop children accessing pornography and other inappropriate material online.

Four leading web providers, BT, Sky, TalkTalk and Virgin, are planning to offer customers the option to block adult content at the point of subscription.

Mr Cameron told the meeting that parents could feel ''it is a jungle out there'' and should be given help and support.
