In the second part of the series, Mishal Husain traces Gandhi's transformation from obscure lawyer to father of the nation and discovers a more complicated and intriguing man than the saintly Hollywood version. Gandhi had to face unpopularity, political failure and British jails. But in 1930 he triumphs - launching the most astute campaign of the age - the 240-mile Salt March that succeeded in humiliating the British Raj.
