Given up on Chesterfield?

Sir: Matthew Parris makes some interesting and accurate points about growing Tory support in the north and Midlands (‘The Tory push north will end in failure’, 7 December). He did not mention Chesterfield in his article, but it is a good example of what he talks about.

It seems to me that the Conservatives have decided Chesterfield is a lost cause, even though it would on the face of it seem promising territory for them.
