Planning Bill

I apologise for intervening so early on, but it is probably an appropriate moment. One of the difficulties that I, and many of the individuals whom I know in local government, have with the Bill is that it is very short on detail. We are used to skeletal Bills, but this one has osteoporosis. Will the right hon. Lady please expand on one or two key points? For example, will she give a definition, at the lower level, of what she would call a nationally significant infrastructure project?
