The chart shows the changing Labour price in the Crewe and Nantwich betting illustrated as an implied probability.

Almost inevitably the money has moved away from Labour following the opinion polls suggesting that Gordon Brown has very little chance of saving the seat.

You can still get money on the Tories but not very much. The price has been squeezed down to 0.05/1 – which means that a successful £10 bet would produce a profit of just 50 pence.
