It's been a long time since I followed British politics closely but the last I looked they were basically a more economically right-wing version of the BNP. Maybe less overt in their xenophobia but still pretty obviously xenophobic. It's one thing to be distrustful of the EU - I don't blame anyone there. It's a fundamentally antidemocratic institution with a large number of other problems. But using that as a reason to oppose other things like multiculturalism, immigration, and most of the other crap they oppose is just absurd.
