David Cameron, the Prime Minister, said the government had struck a deal with housing associations over the proposal to extend the right to buy to housing association tenants. In its general election manifesto, the Tories said they would give the tenants of housing associations the right to purchase their homes at a discounted rate, as local authority tenants can do. The National Housing Federation, the umbrella body for housing associations, most of which are exempt charities regulated by the Homes and Communities Agency, objected to the original proposals and, in liaison with the government, developed a counter-proposal that would allow tenants to buy their homes at discounts, but with the government making up the shortfall between the price paid and the market value of the property. In his keynote speech at the Conservative Party conference, Cameron said: "Greg Clark, our brilliant communities secretary, has secured a deal with housing associations to give their tenants the right to buy their homes. That will mean the first tenants can start to buy their homes from next year.
