Trinamool Congress chief and West Bengal Chief Minister Mamata Banerjee on Wednesday hit out at Modi government saying, every single voice of Opposition is being muzzled.

Mamata Banerjee's reaction came after the Central Board of Film Certification (CBFC) verbally communicated to a film maker to mute four words including 'cow' in his documentary on Amartya Sen.

"Every single voice of the opposition is being muzzled. Now, Dr Amartya Sen. If somebody of his stature cannot express himself freely, what hope does the common citizen have," the Chief Minister said in tweets.
