The hon. Gentleman is right to raise the question of supplies of oil for the future. That is concerning all countries. Not only do we need stability of supply, but, even as we move into nuclear and renewables, we will need a constantly rising supply of oil. That means that we must ensure that the demand for oil is met by supply, otherwise the price will go up again. We are, therefore, looking at what supply of oil there is, and we are trying in the North sea to increase the production that is available from some of the smaller marginal fields as well as from some of the fields that have previously been explored and developed but not exhausted.
