I do not think that there is a difference between us. We are talking about the methods of making assumptions in these matters. I have explained the background to this one and the right hon. Member for Glasgow, Craigton (Mr. Millan) has explained, I would say not very effectively, the background to the one to which he was referring. The principle is the same, and I have made it clear that it is not a figure that is worth having and it cannot be brought together anyway. Therefore, I do not think that it contributes anything to the understanding of the matter.
