My hon. Friend is, of course, right to say that, even if oil and gas are extracted from the continental shelf, they are sold on the international markets. The companies that extract the oil and gas are in the business of trying to make as much profit as possible and will sell to the highest bidder, so it does not protect prices for consumers in this country. We were clear in our manifesto that we will not issue licences for new exploration and new fields, but that we will continue to support those licences that have already been issued. Our future does not lie in more oil and gas; it lies in clean power, which is why we are moving at pace to deliver that.
