I am grateful to the hon. Lady for her intervention, and I welcome her support.
Guidance on the provision of affordable housing requires councils to assess the need based on local circumstances, but such housing is not being delivered in practice. The housing White Paper outlines that that the Government intend to amend the policy framework to introduce a clear policy expectation that housing sites deliver a minimum of 10% affordable homes, but that is not sufficient to address the issues that the planning system is failing to sort out, particularly for first-time buyers. As I see it, it will still be producing the wrong types of housing—perhaps large three-bedroom houses, but also four and five-bedroom houses—when many areas, including my own, need affordable two-bedroom houses. Such homes are more likely to be within the price range of younger people, thereby addressing the problem that the Government identified in the first place: a fall in ownership among young people.
