About 82% of the ₹931 crore wealth attributed to Andhra Pradesh CM N Chandrababu Naidu, India's richest CM according to ADR, is due to his family's shareholding in dairy products company Heritage Foods, company officials said. While Naidu doesn't own any shares in it, his wife Bhuvaneswari Nara's 24.37% stake worth ₹763 crore is counted in Naidu's wealth, they added.
