The first thing to say about Ian Blair is he has actually done a very good job as commissioner of the Metropolitan Police. Not only in terms of the job he has done in London, but in his national role as well because the role of the Metropolitan Commissioner in addressing terrorism is as important on the streets of Birmingham as it is on the streets of London. The second point is when you actually ask someone as we do with the Metropolitan Commissioner to do a difficult and demanding job as an elected politician you should give that person the support to do it. The third thing is, as Sir Ian has made clear, it was because the Mayor said on his first day as chair of the Metropolitan Police Authority that he didn't feel he had confidence in Sir Ian that he took the decision to resign, which I accepted when he came to talk to me about it today.
