The hon. Gentleman is right to say those words to all Members of the House, and to all members of this and former Governments, too. I have talked to Opposition Members, who have made it clear that the inquiry for which we are calling must look at all historical issues. He is right that there were warning signs. As I did at the beginning of my speech, I pay tribute to the fact that some parliamentarians picked this up, but we all need to look at what is happening and why too many people turned a blind eye to the problem, or did not focus on the sheer horror of what was happening for too long.
Let us be clear about the current criminal investigation. We have seen some vigour and rigour in recent months, which must continue, as the investigation needs to look into the heart of the darkness. Where criminal activity has been committed, it must pursue robust prosecutions and deliver justice too. We must not jeopardise those investigations with what we say in this debate or with the details of any inquiry. It is for the police and the courts to determine the veracity of the allegations, but it is for Parliament to make sure that they can do so, that they are doing so, and to address the wider issues.
