Accusing the Centre of trying to muzzle every opposition voice in the country, West Bengal Chief Minister Ms. Mamata Banerjee on Wednesday condemned the Central Board of Film Certification (CBFC's) proposal to mute certain words from the documentary on Nobel Laureate and Economist Dr. Amartya Sen. <br/><br/>She said, every single voice of the opposition is being muzzled and now it is Dr. Amartya Sen. Ms. Banerjee wrote on Twitter, that if somebody of his stature cannot express himself freely, what hope does the common citizen have? The Chief Minister's comments came in the wake of a recent controversy centring on director Suman Ghosh's documentary "The Argumentative Indian" based on Dr. Sen. According to the filmmaker, the Central Board of Film Certification officials in Kolkata verbally asked him to mute at least four words including 'cow' and 'Gujarat' from Sen's interview in the film.
