Can I just finish this point? The noble Lord, Lord Best, made the point very effectively that in one case you can get four times the number of units by disposing of one. It seems to me that, if one stands back and looks at the policy in macro terms, one is increasing the supply of housing stock by generating new build without diminishing the assets that exist at the moment. I accept that there is a change in tenure and that may be the point that the
noble Lord, Lord Beecham, is going to make. However, in terms of housing policy, one is recycling assets in order to increase supply. The Treasury—I speak from experience—has normally been against hypothecation, but in this case it seems to have insisted on it by insisting on a linkage between revenue and expenditure, and I understand why it has done that.
Picking up what my noble friend Lord Horam said about flexibility, I think that it is important so to define high value that not all the large properties in a local authority area are disposed of. One has to retain a balance of stock. I hope that “high value” will be defined in such a way in London that local authorities in the centre of London do not find that all their properties are defined as such and they have to dispose of them. I take the point made by the noble Lord, Lord Best, and others about the situation in rural areas. I think that one needs to be flexible, but I am prepared to stand up and defend the overall principle of the policy.
