Gordon Brown - 5/4 to go by Saturday.

From William Hill:

Following the departure of James Purnell, William Hill have slashed the odds that Gordon Brown will be out of power before the end of next Saturday (June 13th) from 4/1 to 5/4 and Alan Johnson has been cut from 6/4 to Even money favourite to succeed him. Hills also make Brown 11/10 to be gone before the General Election.

"Although James Purnell may well have paved the way for the departure of Gordon Brown, we don't think he is likely to become Leader as a result and have lengthened his odds from 14/1 to 20/1 while Alan Johnson remains red-hot favourite at Even money", said Hill's spokesman Graham Sharpe.
