My hon. Friend makes an important point. It is about not just population density, but unique areas. In my constituency, the villages of Allerton Bywater and Great Preston have many unmapped mine shafts. Looking at what is happening in Lancashire with seismic movement, there is a real concern with the exploratory licence that has been granted that, in areas with unmapped mine shafts, seismic movement will cause collapses and sinkholes at the top. Decisions at the local level are, therefore, more important in this kind of planning application.
