An intense boardroom battle is brewing at India's giant Tata Group

An intense boardroom dispute is brewing for control of Tata Group, the Indian multinational conglomerate that owns Jaguar Land Rover and Air India, and is a key supplier for Apple. On Thursday, Noel Tata, the heir of the Tata family and the chair of Tata Trusts, said that the reappointment of N. Chandrasekaran as the chairman of Tata Sons earlier in the day was "illegal." Noel Tata wants to keep Tata Sons private to safeguard its current ownership, experts said, while Chandrasekaran wants to grow the business by making large, bold bets that require massive capital.
