I think many of us have criticised the selling off of council houses, compounded by the fact that the Conservative governments that followed Thatcher made no attempt to replace them.
Source: Full Fact UPDATE: This article has been updated with more information on housing association builds and the timeframe in question.
While Labour has promised that it would double the rate of housebuilding by 2020 (equivalent to some 240,000 homes per year), one of its London Assembly members has argued that the party should "apologise" for its record on affordable housing.
Tom Copley, Labour's housing spokesman in the capital, said that Margaret Thatcher's government had built more council flats and houses in a single year than New Labour's managed in its entire period in office.
This is correct. The official data shows that the Blair and Brown governments built 7,870 council houses (local authority tenure) over the course of 13 years. (If we don't include 2010 - the year when David Cameron became PM - this number drops to 6,510.) Mr Copley has contrasted this figure with the record of Mrs Thatcher's government, which never built fewer than 17,710 homes in a year.
Between 1997 and 2010, of the 2.61 million homes constructed, only 0.3% were local authority tenure. Mrs Thatcher's government supervised the building of a similar number of houses (2.63 million), but 18.9% were LA or 'council' properties.
To look at it another way, New Labour built an average of 562 council houses per year. And Mrs Thatcher's Conservatives? 41,343. That said, it's also true that the number of council houses under construction declined steadily during Mrs Thatcher's era.
