I recognise the way in which my hon. Friend has championed a number of cases—he has referenced one of them—over the years in this House. Indeed, I had a number of meetings with him when I was Home Secretary in relation to that case. It is important that our police are able to operate to the highest professional standards. They have operational independence as to who they investigate and how they conduct those investigations, but I am sure the whole House would want to say that we expect our police to conduct those investigations properly and fairly, and to ensure that, when a crime is committed, they are investigating that crime.
