I begin my remarks by paying tribute to the Government taskforce on child protection on the internet for its work, and in particular to sub-group A, which formulated the thinking behind the clause. I pay tribute to the hon. Member for Mole Valley (Sir Paul Beresford) and to the hon. Member for Sutton and Cheam (Mr. Burstow), who are members. The taskforce membership is wide, including the Metropolitan police paedophile unit, the Crown Prosecution Service and a wide range of children's charities, academics and others with an interest. It is an exemplary form of modern governance to bring together experience of that kind to get our minds around such key issues and come forward with proposals that will work in practice.
