Maybe the Right of the Tory party (voters that is ) voted BNP in Derbyshire. The Norman Tebbit wing of the party are clearly pissed off with Cameron (a la the Tony Benn wing of the Labour party wass with Blair ten years ago).
As a rule the BNP mostly draws its votes from Labour voters, a mix of the disaffected and frustrated white working class voters (who Labour have struggled to get to the polls with the decline of traditional industries) along with a fair slice of aspirant lower middle class and blue-collar Tories.
It’s hard to imagine hard right Tories voting for the BNP. Generally the BNP are pretty much old fashionedly socialist on most economic issues, which won’t sit well with your average Tory, no matter how disaffected – though I don’t doubt that what’s left of the old blue collar Tory vote could be won over by a BNP campaign.
