Professor Sunil Khilnani from the King's India Institute in London, on the life and legacy of the Indian business tycoon Dhirubhai Ambani, founder of Reliance Industries. The son of a penurious schoolteacher, Ambani credited himself with an almost animal instinct for trading, coupled with a steel trap memory and an appetite for audacious risk. Today fifteen per cent of all India's exports go out in his company's name. It's the ultimate rag to riches story, mixed with street cunning and dazzling deals. In one case, which began with a tip from an underworld don, Ambani executives were accused of violating the Official Secrets Act by possessing sensitive Cabinet documents, including a draft national budget. A joke quickly did the Delhi rounds: the budget wasn’t leaked to Reliance; Reliance had leaked the budget to the ministry.Producer: Mark SavageEditor: Hugh Levinson
