I welcome the Secretary of State's commitment to a debate. One of the keys to the number of houses we will need to build in the future is how well we look after the existing housing stock. Is he satisfied that the Government are spending sufficient money modernising the existing stock? The Secretary of State hinted that he wants new building of high-rise flats and deck-access flats. If so, is he satisfied that local authorities and housing associations have sufficient resources to spend on the communal areas of existing flats to ensure that we do not lose them from the stock and therefore need more new dwellings built?
