This is why I made my point about the national planning policy framework and how it fits within the local plan structure, with which I know the hon. Gentleman will be more than familiar. We are looking carefully at the thousands of representations that have been made—as I have said, the consultation closed in the last week or so—to ensure that there is protection for the green belt.
This is equally about understanding what lies behind the slow build-out rates. Work is being done on this by my right hon. Friend the Member for West Dorset (Sir Oliver Letwin), and his report is due by the Budget this year. If he finds evidence of unacceptable land-banking, I again say that we will not hesitate to act.
Our second focus is on the facilities needed to deliver homes faster. We are making serious investments in roads, schools and communities. For this reason, my right hon. Friend the Chancellor of the Exchequer doubled the housing infrastructure fund to £5 billion in his autumn Budget. Soon after, we announced the first initiatives of the fund. They involve 133 marginal viability fund projects worth a total of £866 million, and they have the potential to unlock up to 200,000 new homes.
