My Lords, I make it clear that the £17 billion does not in any way relate to the regulations that we are debating tonight. So far as concerns the regulations under discussion tonight, a question would arise with regard to backdating only if people failed to be paid what, under this legislation, it was their right to be paid. However, it is hardly likely that there will be a failure to do that. But, if they failed to be paid what was due to them under the legislation, then of course the amount would depend entirely on how many people failed to receive the rights that they have under this legislation for whatever period. This is backdating for a right for which people have not been paid. Therefore, it depends entirely on the extent to which they have not been paid. Therefore, at this stage it is not possible, even remotely, to say what that would be.
So far as concerns the £17 billion, that figure is not accurate. Our figures are much lower than that; £4 billion is probably closer to the figure. However, we need to examine that in more detail.
