My Lords, as one of the Housing Ministers in the 1979 Parliament, I say to the noble Lord, Lord Bird, that I do not recall the right-to-buy legislation being in my briefing pack when I took office. Returning to the original Question, I agree that we need more affordable homes. Has my noble friend seen a report by the Home Builders Federation that 13,000 sites for affordable homes have been earmarked as a condition for market sales on the rest of the site but no housing associations or local authorities have come forward to claim them? Can my noble friend find a solution?
