I think you are referring to the Colin Buchanan study, which essentially was making the case for expansion elsewhere, as I understand it, although it clearly did put some negatives in there. What we are looking for, given that the Government's case is essentially economic ' Ruth Kelly [Secretary of State for Transport] is saying that jobs will be lost and the economy will suffer ' is a very focused rebuttal of that argument. The sorts of things that we are looking for is the effect, given we have a skills and labour shortage in London, of, for example, having more construction beyond Terminal 5 at Heathrow, and the effect of that on Crossrail, increasing the costs of Crossrail; that if we expand airport capacity beyond the already massive expansion at Terminal 5, that undermines the economic case for additional fast rail capacity; that increased traffic and congestion in west London is going to damage the economy; that additional noise and pollution across London is going to damage the economy. What we need, I would put it to you, is a very focused economic rebuttal of the case for Heathrow expansion. I would press upon you, in addition to the welcome news you give us today, that short haul is going to be looked at. We have to win this argument on the economics essentially, would you not agree?
