New Delhi, Nov 10 (PTI): Tata Sons has appointed Ishaat Hussain as the Chairman of the group's hugely successful IT firm TCS in place of Cyrus Mistry, who was ousted last month.

"The company (TCS) has received a letter dated November 9, 2016 from Tata Sons Ltd nominating Ishaat Hussain as the Chairman of the Board of Directors of the company in place of Cyrus P Mistry with immediate effect.

In view of this, Mistry has ceased to be the Chairman of the Board of Directors of the Company and Hussain is the new Chairman of the company," TCS said in a regulatory filing.
