My right hon. Friend is absolutely right: sustainable planning must be at the heart of our planning system. That is why we are committed to meeting the needs of communities by building homes in the right places and, as he says, making best use of brownfield land. We have made it clear that that is what the priority should be and we have put extra funding aside to unlock those sites. Our recent changes to the national planning policy framework provide clearer protection for the green belt, making it clear how future housing supply should be assessed. That is the clear difference between our two parties: the Conservatives will protect the green belt and Labour will concrete all over it.
