Anil and his brother, Mukesh, the world’s 34th and 7th richest people, have been locked in an increasingly bitter feud over India’s biggest natural gas deposit, a battle between the famous sons of one of the country’s first great capitalists. At issue is the sale price of natural gas from India’s largest known deposit: The Krishna Godavari basin, off the eastern coast, which doubled the country’s known gas supplies when discovered in 2002.
