§ Dr. Lynne Jones
To ask the Secretary of State for the Environment, Transport and the Regions if he will take steps to ensure that homes for which planning permission is given on the basis of affordability remain affordable on re-sale or reallocation. 
§ Mr. Mullin
We already provide guidance to local planning authorities on this issue. Planning obligations and conditions may be used to ensure that affordable housing provided through planning policy is secured, either initially or in perpetuity, for occupation by people in need of such housing. Detailed guidance is set out in Planning Policy Guidance note 3: "Housing" and Circular 6/98, "Planning and Affordable Housing". All affordable housing provided by Registered Social Landlords using Social Housing Grant must continue to be let at affordable rents as a condition of receiving the grant.
