Order. I believe that the House has benefited by the progress we have made at Question Time this week. [HON. MEMERS: "Hear, hear."] This is no easy task for the Chair and if I occasionally make mistakes I hope that the House will pardon them. All I would ask the House is that if ever I appear a little brusque this should not be taken in any way as a personal reflection on any hon. Member. An hon. Member's duty is to strive to press his Question; mine is to think both of him and of 629 other hon. Members.
