One of the odd things about politics is that there is no heir apparent to Cameron in the Tory party. Hague used to be considered the obvious emergency replacement. But that is no longer true. The bookies have Boris as a good bet to replace Cameron and he'd definitely attract considerable support. Yet, he'd have to get back into parliament before he could stand and make it through the MPs' round first. Then there's George Osborne who is canny enough to recognise that any speculation about him becoming the next leader would not be helpful to his cause. This leaves Hunt as the most talked about option by MPs. But the risk of all this to him is that it rather puts a target on his back.
