Order. Members have not been too bad at sticking to the time limit suggested earlier, but as the House can see, a great many people still wish to speak. I would like to try to impose a voluntary time limit of six minutes. [Interruption.] I appreciate that this is a bit of a surprise for the hon. Member for Banff and Buchan (David Duguid), who has much to say on this subject, so I shall not hold him to six minutes, but everyone else is now warned.
