Asia’s richest man Gautam Adani sees his fortune shrink

It was a pretty extraordinary day on India's main stock exchange on Friday. Shares in the business empire of Asia's richest man Gautam Adani plunged some 20 per cent, extending earlier losses at the Adani Group to some $45 billion. The price fall comes after a report by an American firm alleging stock manipulation and accounting fraud, claims the company denies.
