DAVID CAMERON set to brag today about his new Thatcher-style housing scheme which will bring an extra 30,000 homes into the private sector.   The Prime Minister will reveal that his government will commission private developers to build on publicly owned land in a move inspired by Thatcher and Michael Heseltine’s social cleansing of the London Docklands.   An extra £1.2 billion has been earmarked for “starter homes,” which campaigners labelled as PR spin to offset cuts to social housing.   Making his first policy announcement of 2016, Mr Cameron will say: “Nothing is more important to achieving [security and opportunity] than ensuring hardworking people can buy affordable homes.   “Today’s package signals a huge shift in government policy. Nothing like this has been done on this scale in three decades — government rolling its sleeves up and directly getting homes built.   “Backed up with a further £1.2bn to get homes built on brownfield sites, it shows we will do everything we can to get Britain building and let more people have the security that comes with a home of their own.”   A pilot of the scheme will be rolled out at five sites, including the Connaught Barracks in Dover and Old Oak Common near London’s Wembley Stadium.    Labour’s London Assembly housing spokesman Tom Copley, however, said the government was “abusing” the word affordable as London starter homes built under the scheme can cost up to £450,000 each.    “It’s easy to claim you’re building a record number of affordable homes when you redefine the term to include homes that most people would regard as unaffordable,” Mr Copley told the Star.   “If the government was genuine about dealing with the housing affordability crisis it would lift the arbitrary cap on council borrowing for housing and end its attack on social housing, which is genuinely affordable.”   He added that today’s announcement promised “no new starter homes beyond those already announced.”   Housing campaigners echoed the Labour politician’s views that the scheme was disingenuous.   Lobbying group Priced Out national organiser David King said: “Millions of people are struggling in the private rented sector.   “At best, this announcement will help a select few to buy a home, but it comes on the back of reduced spending on social housing.   “The government’s ideological drive toward home ownership is denying people a chance to live in a secure home, whatever their needs.”
