My hon. Friend will be pleased to see in the document that we have suggested that we might use the same kind of sequential judgment as that used for out-of-town shopping. We start by asking why the development cannot be built in the city centre, and, if it cannot, we ask whether there is a moderately close position. Only then can green-field sites be considered.
That is one of the propositions, and I hope that my hon. Friend will add his support to it if he feels that that is right. He is absolutely correct to say that it is unsustainable to believe that we can meet the requirements of the kind of life style that we have largely decided for ourselves merely by spreading houses across the countryside. That would not be right, either for our own generation or for future generations.
