Housing: Long-term Plan

The Minister is generous in giving way. On the point about extra supply, he said—I do not quite know which schemes he was referring to—that in some London schemes there is evidence of a 2:1 replacement, rather than the wider picture of a 1:10 under-replacement. Will he tell me a little more about that scheme, and does he believe that when the right to buy is extended from the five pilot areas, once a property is sold it will be replaced twice over in all the areas where the right to buy applies?
