The hon. Gentleman makes a strong point. I agree that we cannot simply build our way out of the current housing crisis faced by the UK, particularly in the south. Does he agree that what we should do—the Barker review did not address this matter—is build up an intermediate market for those people occupying the big gulf between low earnings levels and high house prices in areas such as my constituency? Simply building more houses will never make any significant impact on that enormous gulf.
