Yes, my right hon. Friend makes the point very well.
The first way in which neighbourhood plans can be vulnerable to speculative development—even when it was thought that they would protect areas—is when there is not a sufficient five-year land supply in the local authority. The problem with that is that the five-year supply is not always properly in the hands of the local authority, but depends on the ability and willingness of local developers to build. Developers are undoubtedly gaming the system so as to secure speculative development applications and planning permissions, in a way that is deeply cynical and that is undermining the principles of localism and community control.
