popularity contest between David Cameron and Boris Johnson

A poll conducted for the Independent newspaper published on Monday showed Johnson has emerged as Conservative activists' first choice to replace Cameron, with 32 percent wanting him to take the top job in British politics when Cameron steps aside.The Guardian newspaper said Murdoch might be set to back Johnson to take over as leader of the conservatives from Prime Minister David Cameron. The newspaper cited sources familiar with Murdoch's thinking, and referred to his tweeted praise for the organisation of the Games so far.
