'The Big Fella', Jack Lang was one of Australia's most controversial politicians; he was loved and hated with a visceral intensity.

Lang was twice Premier of NSW. During the depths of the Great Depression he was dismissed from office by the NSW Governor for refusing to repay interest on Commonwealth loans. He was expelled from the Labor party in 1942, and re-admitted in 1971 with the support of his young protégé, Paul Keating.

Former PM Paul Keating and historian Frank Cain discuss Jack Lang's life,

legacy and the Depression.
