David Cameron: I Don't Keep People In Jobs Because They Are Friends

As ashen Conservatives were coming to terms with the chaotic results of the last general election, Rachel Johnson, sister of the Mayor of London, tweeted: “It’s all gone tits up. Call for Boris.”

Two years later, David Cameron finds himself once more taunted by the Frankenstein’s monster he created as Mayor. As the Prime Minister’s personal ratings slump, the Boris Johnson campaign trail is the only show in town. London’s version of Gerard Depardieu, part man, part appetite, Boris is an oxymoron, a popular Tory. His unofficial campaign slogan has become BojoGotTheMojo.
