A man from one of India's poorest states has become the first person to win a $1m jackpot on the Indian version of Who Wants to be a Millionaire. Sushil Kumar, a computer operator and tutor from the eastern state of Bihar, took home the top prize on popular game show Kaun Banega Crorepati. The winner's brother, Sudhir Kumar, said he was well-prepared for the show. He said the reason that Mr Kumar was so informed was that he was a regular listener to the BBC's Hindi service. Mr Kumar's win echoed the plot of the blockbuster film Slumdog Millionaire. "I never thought in my wildest dreams that I could do this," he said. The 27-year-old, who was married five months ago, earns a monthly salary of less than $150 (£93.75). The BBC's Nitin Srivastava said Mr Kumar planned to use his winnings to pay off his debts and buy a new home for his family. Hosted by Bollywood star Amitabh Bachchan, Kaun Banega Crorepati is one of India's most popular shows, and has offered vastly increased prize money this season.
