I am a member of a local authority. Between voluntary housing and local authority housing we do not seem to have a difficulty with regard to the expansion of housing. The problem is in getting tenants for certain housing schemes. As a result of the tenant purchase scheme and the council buying one-off houses, quite often the very good tenants have become owners of their houses. The difficulty we have in estates in my constituency and around the country is in getting tenants into the houses. In some local authority estates, as a result of what we did in the past, we have created potential ghettos on the basis that the tenants left inside feel trapped because the local authority will no longer buy houses from them. In many cases a small number of tenants are creating a nightmare for others.
