The proposals, which will be a key part of Labour's general election campaign, were being announced by John Prescott as part of his five-year plan for housing. At its centre is expected to be a plan to build new first-time buyers' estates using surplus government land, such as obsolete London hospital sites. In a radical new idea, the state will continue to own the land but homes built on it will be sold to people priced out of the regular housing market.
