"Inconsistent branding" admits top Tory MP

We bumped into a front bench Conservative MP today whilst we were campaigning for Greg Stone in Sedgefield. Asked why the Conservatives were promoting David Cameron heavily in the Ealing Southall by-election (including making his name part of the candidate's party description) whilst in Sedgefield the name of David Cameron makes no appearance in the candidate's description on the ballot paper (and very little mention in their campaign literature), back came the reply of "Inconsistent branding!" This was followed by a reference to the North-South divide! I won't say which leading Conservative said this!
