Does my right hon. Friend accept that John Hemming is displaying more than a little opportunism and hypocrisy, given the background of the Liberal Democrats' energy policy? Although he is right to raise the issue of gas supply and demand being in balance, he and his party fail to tackle the issue of the country's energy supplies being in balance. Will my right hon. Friend confirm that the Government's policy is to ensure that there is a balanced energy supply in this country, especially on the base load?
