The chairman of India's Tata Sons, N. Chandrasekaran, said on Wednesday that he has resigned in light of the lack of board approval for his reappointment amid tensions with the charity arm that controls the salt-to-aviation Tata Group.
Tata Trusts, the group's charitable arm, owns about 66% of Tata Sons, which controls more than 30 group companies in the Indian conglomerate.
