National Security

Order. Before I call the next hon. Member, may I say to the House that these are important matters and I am anxious to call as many Back Benchers as possible? No Back Bencher has yet asked a question, and we have had more than 40 minutes on the statement. There is another statement to follow and a heavy programme after that, so may I please ask for the briefest of questions from every Member? We will try to get as many Members in as possible. Perhaps I could also ask the Prime Minister if he, too, would not mind being as brief as he can.
