Finance Bill

I am wisely warned that that question invites me to stray rather far from the Finance Bill. If I can ask the hon. Gentleman to conceal his excitement, that is one of the issues that will be covered in the forthcoming economic assessment report. I warn him that it is not an easy question to answer, as an awful lot of complicated arithmetic will have to be done by all sorts of people to come up with a sensible answer to that problem. What I can tell him is that if we were in government, we would have decided it by now, because the matter is urgent. We need to know what the Government are going to do, because we are very close to the point where the nuclear stations have to be retired or closed. If we do not replace nuclear with nuclear, another fifth of our generating capacity is going to be generating carbon dioxide—unless there is a magic formula on renewables.
