Hague is not fond of Basher Davis, and his endorsement of another candidate will carry some weight, if he endorses Doc Fox in return for a promise of the shadow chancellorship – which the over-promoted Gideon Osborne* is unlikely to hold on to under the new management – or the shadow foreign secretary position, don’t be surprised.
If Hague were to endorse another candidate, such as his friend and former leadership campaign manager, Alan Duncan, or even Lansley, it would considerably improve their chances. But he is not likely to support a left-wing candidate and Hague is probably calculating that Doc Fox has more chance of defeating Basher. He is also unlikely to support Cameron, who is younger than himself, given his own experience.
*Yes it really is Gideon, he changed it to the more populist George so he wouldn’t sound like a privileged heir to a baronetcy in these democratic times. Guido prefers to use the more posh, original name his mother gave him – it suits him.
