It is quite extraordinary that Boris Johnson is leading the polls for London mayor; one can only assume the voters haven't heard him much. I have just watched the most inept, extraordinary performance I have seen by any politician in years on Newsnight. Boris hadn't a clue how much his treasured Routemasters cost. He said the mayor should earn less, but had no idea to what. All the time, one had the impression of a politician making it up as he went along, including a 90 second intro that he had plenty of time to rehearse. Goodness knows what this buffoonery would lead to in City Hall. I can see why he doesn't like doing too many debates in this election, but surely that was one thing Eton was supposed to equip you for?
