Does my right hon. Friend agree that, in determining how much accommodation we will need in the future, we should take into account not only extra households but the number of places in care homes for the elderly? Does he further agree that one way of ensuring that development takes place in urban areas and not on green-field sites is to encourage local authorities to write policies to ensure that into their local plans? If that were done, councils deciding on planning applications would have a good reason for refusing one for a green-field site, because the development would not be inside an urban area. In addition, writing such a policy into the plans would make it less likely that a decision to refuse an application would be overturned on appeal.
