Developers behind the cluster of garden cities in the south east would not have to meet an affordable housing quota, despite Nick Clegg's claims the developments would offer low-cost accommodation, it has emerged.
Communities minister Nick Boles, said the Government would "not impose a particular level of affordable housing for housing schemes," when quizzed by Labour.
"Unrealistic Section 106 agreements [which specify how many affordable homes should be built] result in no development, no regeneration and no community benefits," he added.
Nick Clegg said the new cities containing 15,000 homes each would create "an arc of prosperity" in the South East.
A spokesman for the Department for Communities and Local Government confirmed there were no Whitehall targets for the number of affordable homes in garden cities.
