Sarah Christie meets Martin Rowson

Political cartoonist and renowned cynic Martin Rowson is off to the zoo to draw and interview one of Britain's leading tiger experts, Sarah Christie. Martin is a self-confessed zoo enthusiast, and Sarah has had great influence on his work in conservation.

This is the fourth sketch in a five part series, where Martin draws and interviews people who have shaped his work and wider life. He also puts pen to paper with ex-Chancellor George Osborne, journalist Julia Langdon, illustrator Ralph Steadman and punk poet John Cooper Clarke.
