In the letter to the shareholders, Ratan Tata asked for the support from everyone in taking this vital decision. He further explained that the board lost confidence in him on leading the giant conglomerate.

Earlier, the sudden decision on sacking Cyrus Mistry as the chairman of Tata on 24th October shocked the corporate sector. Though the allegations and conspiracies were uprising since the first day, they further deteriorated now.

“The right step would have been for him to resign as director. Unfortunately, he has not yet done so and his continued presence as a director is a seriously disruptive influence on these company boards, which can make the company dysfunctional, particularly given his open hostility towards the primary promoter, Tata Sons,” Tata wrote.

“As a final step, he was offered an opportunity to step down voluntarily from the Chairman position, which he rejected and said that it should be taken up at the Board,” Tata wrote further in the letter.
