My Lords, I am grateful to the noble Baroness, with her extensive experience in this field. She is of course right that we can be proud of how the police and MI5 have addressed their own performance in the way that these cases have been investigated. David Anderson is very clear that their process was thorough and fair. Nevertheless, it is reassuring to us all that we did commission David Anderson to do this exercise. It was not that the police and MI5 were not trusted to do the job but, on some occasions, we need that added element of reassurance which we have received clearly from Mr Anderson.
