I know that the Liberal Democrats support the Government on that and note the sedentary remarks from one of only two Liberal Democrats in the Chamber today. It is typical of the Treasury to hold back key information on these facts and figures. We need to know where those properties are and what valuations have been made. The Exchequer Secretary has done the work on the annual tax on enveloped dwellings, but he did not say that he would publish those findings. I think that we might be about to reach some consensus on this, because he is suggesting that the Treasury has done some work on it secretly, rather like the secrets held back in the spending review document, which was so thin that we still do not really know where the cuts have hit. Why does he not publish that information and start telling us how that could work in those circumstances? Will he publish it?
