SD = BNP
The Sweden Democrats are not so much far right as your common-or-garden populist party and get their voters from young unemployed poorly educated males and a few old age pensioners.
I guess it is part of Sweden becoming more European; now we've got a populist party with a murky ideology in our parliament, just like most of the rest of Europe. The Westminster system, while perhaps a little unfair, does keep the likes of the BNP at bay.
