Now it's perfectly  now  the cost er the benefits from sort of marketing right to buy is really very, very dubious erm the government has shown time and again that what it takes then gives with one hand, it takes away with another and the costs are obvious, we are fragmenting our housing stock, we are putting it, we are likely to end up with more and more with a higher proportion of poor properties  and erm there's also the risk that if we do really have to be promoting right to buy we're going to have people who are probably not sure whether they can afford to buy their house or aren't sure whether they even want to buy their house.
