I am always pleased to agree with the hon. Gentleman when it comes to energy matters, especially on energy efficiency and energy-saving policies, and to that end I agree with the thrust of his remarks. As regards oil and gas, of course we should like increased production and we should like to ensure that we do not need to become an importer. However the reality, which I know that he accepts, is that in recent months production has had to be restrained, despite world demand for increased production before the Gulf crisis, because of the importance of safety and of ensuring that topside emergency shutdown valves are in place. Safety has been the top priority and that is the reason why production has not been at the highest possible level, as we should have liked.
