I am grateful to the hon. Gentleman because he gives me a chance to pay tribute to ChildLine. I was at its London centre last week. Those who volunteer and those who work for it professionally do remarkable work to help our young people deal with some of the challenges of our modern existence. He is right that cyber-bullying is particularly pernicious; it does not go away and it happens to young people whether they are at school or not. It is having a serious effect on their mental health. I hope that he will see in the White Paper, and what will follow it, a clear commitment to say to online platforms that they must do all they can to protect users from this kind of abuse. We do not expect anything unreasonable and we do not expect anything impossible, but where they can address this issue they must.
