The job of mayor of London is unbelievably taxing, particularly in the run-up to the Olympics.

So I'm definitely in favour of stimulating the dynamic wealth creation sectors of the economy.

I want London to be a competitive, dynamic place to come to work.

The volunteering spirit of Londoners is part of what makes this the best big city on earth.

My friends, as I have discovered myself, there are no disasters, only opportunities. And, indeed, opportunities for fresh disasters.

The only reason I wouldn't go to some parts of New York is the real risk of meeting Donald Trump.

I lead a life of blameless domesticity and always have done.
