Tonight's episode of the five-part Arena biography tells the story of Orwell's marriage to Eileen O'Shaughnessy , his growing political awareness and retraces what was to be the most important journey of his life-the trip he made to Wigan and the industrial north in 1936, in an attempt to understand the embittered and divided working class of the 30s. Among those appearing are Sir Richard Rees , Kay Ekkeval, Geoffrey Gorer and the people of Wigan and Barnsley.
