Maybe, maybe not. Either way, that's not the point. The point is that he's being paid £6 million a year to do something that other people could do quite easily for sensible money. How is his salary justified?
Well why do you think he's the one doing it? Let me see, because he's good at his job? Surely he doesn't deserve £6 million for it but would you turn £6 million down? BBC are clearly making a profit so therefore his salary is more than justified from the employers perspective.
