Mistry also ceases to be the chairman of the company following his removal as director, Tata Industries said.
"Tata Industries, at its extraordinary general meeting on December 12, 2016, removed Cyrus P Mistry, as a director of the company. Hence, he also has ceased to be the chairman of the company," it said.
Mistry was abruptly ousted as chairman of Tata Sons -- the holding company of the USD 103 billion salt-to-software conglomerate -- on October 24. Since then, interim Chairman Ratan Tata has moved to consolidate his position by seeking to remove Mistry from boards of key listed firms.
The board of Tata Industries, post the EGM, comprises, KRS Jamwal, R Bhinge, Ireena Vittal, Ashish Dhawan, N Srinath, and F N Subedar.

Mistry, on the other hand, had alleged that Tata and other trustees of the Tata Trusts ran alternate power centre and he was reduced to a "lame duck Chairman".
