David Cameron's ideas for reform of the planning system are the most radical piece of localism I've seen proposed in this election campaign so far.
Cameron envisages a switch from a local-authority-led system of plans against which new developments are judged, to a more permissive community-based system. Communities would come together in a participatory process to define a new community plan. Local authorities would then stitch those together into Local Plans, but would lose the right to make individual judgements on any planning application within the scope of the Local Plan.
