Gajendra Chauhan, whose appointment as Film and Television Institute of India (FTII) chairman has faced protests from its students, should "voluntarily retire", says veteran actor Rishi Kapoor. Chauhan, who played 'Yudhishthir' in "Mahabharat", was appointed as the FTII chief last month. This was followed by protests from students, who believe he lacks the stature and vision to head the institution.
