On the specific point of retail energy markets, a two-year investigation has been carried out by the CMA, and it is now for Ofgem to respond. I hope it will respond and eradicate that deficit; that is the test that Ofgem faces. We have made it clear that we will rule nothing out if it falls short, but I do not want to remove the obligation on it to respond in that way. I hope that the hon. Lady will welcome our intention to publish a consumer Green Paper and that she will contribute to it. This will look across the board—across other utilities as well—to see whether the existing regulatory arrangements are sufficient.
