Yawn.  Political party contains corrupt members shocker!  Wow - I'm blown away (not).

Has there ever been a political party that hasn't contained people who've fiddled expenses or has behaved anything less than perfectly?  The answer's no by the way.

This is just a straw man argument - you seem to be suggesting that if people within UKIP are less than perfect then that's a good reason to stay in the corrupt, rotten-to-the-core, extremely expensive, empire-building EU.  Thankfully, the electorate clearly don't see the world in this distorted way.

If nobody voted for a party that included anyone imperfect then nobody could vote for anything, ever!
