David Maddox: The Numbers Game returns

Things are getting so bad for Gordon Brown that bookmakers have now started taking bets on how badly the public think of him.
Paddy Power is asking punters to put their money whether their mouths are on the beleaguered PM's latest Yougov approval rating and the one he will have at the next election.
Even though he claims that he has now fixed the economy, I fancy any of the odds 4/1, 6/1 or 8/1 for the various estimates below 20%, especially after his latest McAvity act on the Lockerbie bomber.
Here are the odds:

Gordon Brown September Approval Rating
8/1 10% or Less
6/1 11% - 15%
4/1 16% - 20%
11/8 21% - 25%
3/1 26% - 30%
9/2 Over 30%

Gordon Brown’s Approval Racing At The Next General Election
6/1 10% or Less
5/2 11% to 20%
11/8 20% to 30%
7/2 30% to 40%
8/1 Over 40%
