Profiling Ronald Searle , one of Britain's greatest graphic artists and the creator of the St Trinian's cartoons who, after growing exasperated by the public's obsession with the fictional schoolgirls, left the country in 1961. But what effect did Searle's self-imposed exile and experiences in a Japanese prisoner-of-war camp have on his work? Featuring contributions from fellow cartoonists Gerald Scarfe, Steve Bell, Martin Rowson and Posy Simmonds.
