Tim Worstall points out (rightly) that the MEP Tom Wise, who was the subject of a rather damning report in the News of the World about MEPs "riding the gravy train" hasn't been a member of UKIP for some time. Ashley Mote, the MEP who was sentenced to nine months in jail for benefits fraud and attempted to avoid prosecution by claiming immunity as an MEP, had the whip removed by UKIP within weeks of his election. As for Robert Kilroy Silk, I'm sure that UKIP would feel the less said, the better. In 2004, UKIP had 12 MEPs elected. In other words, they've lost 25% of their elected representatives, mostly under a cloud (and Godfrey Bloom isn't exactly a walking advertisment for a modern political party either).
This does rather beg the question though - what does it say about the party that thought the three of them were fit to nominated in the first place?
