I take the Minister's point. As I hoped, he is taking this matter seriously. However, I made it clear that I am not saying that we or Liberty have necessarily got the provision exactly right. Does the Minister understand that we are trying to avoid improper restrospectivity? It would be helpful if he at least kept the matter under review to see whether there is a way to address Liberty's concern while not having two systems running in parallel as he described. I understand the Minister's point about paedophiles and murders that are discovered many years after the event. We do not want two systems running in parallel, but equally we do not want improper and unnecessary
retrospectivity. Will he at least undertake to continue considering the issue?
