Okay, where are we starting off? Is he a right-wing bonehead who just gravitated to UKIP? Is he a liberal? A really confused social-democrat? I mean, the further to the left he is, the more you should focus on their racism. If they're right wing to begin with, then instead of focusing on racism you should focus on the unworkability of their petty-nationalist, reactionary politics in general.
If not, I guess you can look up Nigel Farage quotes or whatever. I mean, they haven't been in power yet, so you can only judge them based on what they say (or you can read their official political platform if you really care, but that's probably carefully sanitized so that it doesn't offend potential left-wing voters while still appealing to their right-wing core, so it'll probably be vague and useless for the purpose of argument).
