The Central Bureau of Investigation (CBI) lens on R Venkataramanan, managing trustee of Tata Trusts and director in AirAsia India board, along with AirAsia global chief Tony Fernandes, has put the spotlight again on the allegations made by former Tata Sons chairman Cyrus Mistry in his exit letter to the board in Oct 2016. Mr Mistry had pointed at corporate governance lapses at AirAsia India Ltd, a joint venture between Tata Sons Ltd (49 pc) and Malaysia’s AirAsia (49 pc) which started operations in Jun 2014.
