Shall I go first on that, David?
Let me make almost a political observation, not a party political observation.
I find that there's a lot more public support for the idea of doing something about fuel poverty than perhaps there is about doing something about the wider forms of poverty to do with income and the type we are concerned with. We are holding a seminar on the subject in a couple of weeks, and it's always, I think, a measure of these things. We're having no difficulty getting people to come along. So I think you certainly should. I think people recognize fuel poverty as being something quite tangible, so it should be part of it.
Perhaps I may make one technical point. David did make this point, but I want to elaborate on it just slightly. It is very much to do with single people. Crudely, it's that a single person has half the income of a two-adult household but something around three-quarters only of the fuel cost. And it also is very much related to disability. The people who are really vulnerable on this, I think, are the people who are at home all day. Obviously the disabled out of work are likely to be in that group, but they are equally well reachable through the benefit system, which delivers benefits to them.
