Could I just say that even though what I know about politics would fill an egg cup, his "leadership rivals" lack any sort of charisma, have an enormous amount of baggage from the Blair/Brown years and are seen as typical politicians, ie slimy little no marks that don't give a toss. As ever the one that shouts systemic change the loudest will win. If he becomes leader just wait for the press to dig up his history.....it'll be a bloody good read!
