So Giles Chichester has done for members of the European Parliament what Derek Conway did for MPs.
He's resigned after it was revealed that he broke the rules on expenses when thousands of pounds were paid into a family firm of which he was a director.
Mr Chichester was, would you believe, not just the leader of the Tory group in Strasbourg but the man charged by David Cameron with ensuring that the rules were observed. Team Cameron didn't share his view that this was merely a "whoops-a-daisy" moment.
Understandably, Team Brown cannot resist observing that, once again, it is a Conservative who's been found taking a less than entirely rigorous attitude to paying themselves the public's money.
