I think the hon. Gentleman wants proof. Well, I cannot do a controlled trial, although I used to be a scientist. We cannot do controlled trials to determine what would have happened had we not intervened. All we can do is operate on the basis of the evidence in front of us and try to work out the best way forward. That is imprecise, and it may be unsatisfactory to the hon. Gentleman, but it is none the less true. He wonders why I am not answering questions that have been put to me. The hon. and learned Member for Edinburgh South West rightly raised the position of women and girls. As it happens, she mentioned driving and made some important points that had not hitherto been made. Some people would say that women being able to drive is a trivial matter and does not in any way compare with the sort of human rights abuses cited by other right hon. and hon. Members.
