Don't expect much electoral accountability

There was a lively article by Fergal Davis on the Guardian’s Comment is Free site last week, arguing that voters in this election should hold their MPs to account for the way they’ve voted. Davis’s concern was civil liberties – but the argument could hold for a range of other things, from abortion to Trident, from post offices to Heathrow. Do we punish (or reward) MPs for the way they vote?

For some of his article, Davis uses a book I wrote in 2005, which looked at the voting record of MPs, and which showed that far from being the spineless bunch that everyone claimed, they were in fact becoming increasingly rebellious, with the Parliamentary Labour Party between 2001 and 2005 being the most rebellious of the post-war era. But the book also showed that there was no evidence that voters took much notice of this when it came to casting votes at the ballot box.
