The Prime Minister will acknowledge the issue of extreme and child pornography is "hard for our society to confront" and "difficult for politicians to talk about" in a speech later today.
I want to talk about the internet. The impact it is having on the innocence of our children. How online pornography is corroding childhood. And how, in the darkest corners of the internet, there are things going on that are a direct danger to our children, and that must be stamped out.
"I'm not making this speech because I want to moralise or scaremonger, but because I feel profoundly as a politician, and as a father, that the time for action has come. This is, quite simply, about how we protect our children and their innocence.
I want Britain to be the best place to raise a family. A place where your children are safe. Where there's a sense of right and wrong and boundaries between them. Where children are allowed to be children. All the actions we're taking come back to that.
