The usual regular dry politicians, those from his own party and others who will say that Boris is not your usual choice for pm as if that is a bad thing. As they said in the documentary Boris makes people feel good about themselves he gets people engaged in politics that otherwise wouldn't be. The patriotism and feelgood factor for being British he inspired during the Olympics was brilliant and he made a huge contribution to the success of the summer.
There is a reason that voter turnout is so low in the country and it's because of people like ed milliband and Cameron. I want to see people engaged in politics and Boris will offer that as well as fighting our corner properly in Europe which I totally agree with and I believe he will do what is right for Britain Imo. He is a very clever bloke and again in the documentary one of the people who knows him well said that he believed he would understand the importance of being prime minister and would make wise decisions.
One poor interview is not enough to derail any future campaign for pm and it will be easily explained away when needed.
