Neighbourhood Planning Bill

In respect of the amendments moved by the noble Baroness, Lady Cumberlege, does the Minister expect the department to issue any further guidance at some point on modifications and how minor they may be? I am conscious that government departments might say, “This is a minor modification”. I recently put down a Parliamentary Question to ask a number of government departments about reviews that are announced in Parliament from the Dispatch Box, and I have been told by a number of them that there is no definition of a review. I know that it is a bit odd, but I am therefore conscious that if there is definitely going to be a review, when a Minister stands before us saying whether a modification is minor or not, what status does that have? Would he consider producing further guidance to help residents, neighbourhood planners and parish councillors to understand all of this?
