David Campbell Bannerman MEP today defected from UKIP to the Conservatives. And cue the standard script whenever someone changes party:
The Losing Party: "The people didn't vote for this; there should be a by-election. This defection is just a spot of personal pique! Good riddance to good rubbish!"
The Gaining Party: "Our new recruit is a formidable politician who shows our party is a broad church able to reach out to all. And only a few partisan politicians want a by-election."
Has anyone ever known a serious political party tell a would be recruit that they cannot join until they first have a by-election?
