The Mayor of London, Boris Johnson, today joined some of the UK’s top cartoonists to launch London’s Big Draw weekend. Artists accompanying him at the launch included Tamara Drewe-creator Posy Simmonds, Steve Bell, Peter Brookes, C Michael Heath, Charles Peattie (aka ‘Alex’ of the Daily Telegraph').

These cartoonists helped preview the Big Draw ‘Battle of The Cartoonists’ on giant easels set up on the top floor of City Hall. This event tomorrow sees four national newspaper teams competing to see who can make the most spectacular banner at the Scoop outside the building -- under large umbrellas if the weather forecast is to be believed.

London’s Big Draw Festival will see top artists, cartoonists, architects and archaeologists join Londoners for a two day 'drawing celebration of London's changing river and skyline'. Forty free activities will take place at twelve London locations along the river from London Bridge to Tower Bridge, which are aimed at people of all ages.

"Drawing is not about being the best," said Boris. "It's about putting across the way you feel, right there, in the moment. The world is your sketchbook and I hope everyone will be inspired to join in the Big Draw.
