May I take the right hon. Gentleman back to UK-wide matters on the cost of energy? I wish to make three brief points. First, does he agree that the hundreds of social tariffs should be simplified and standardised, and that they should be more generous? They are very confusing and do not give everyone access. Secondly, we should end the obscenity of people on pay-as-you-go tariffs, with the poorest in society paying more per unit of energy. Thirdly, we must ensure that people without access to direct debits-again, the poorest in the country-have access to the discounts that are available.
