At the Shard building in London today, enjoying a glass of breakfast champagne with Mayor of London Boris Johnson.

Sad to say it was nothing to do with 100 Days, 100 Grand – my alma mater Warwick Business School was opening its London outpost (that’s the Dean and Vice Chancellor to the right of Boris) – but it was fun to pass on a caricature of the Mayor kicking down the door of No 10, drawn by my pal Simon Ellinas. (Who also cartooned at my wedding earlier this year!)
