Actor-politician Kamal Haasan today joined a growing chorus of voices uniting against Amit Shah after the Home Minister, on Saturday, re-ignited the controversial debate over Hindi becoming the national language. The Makkal Needhi Maiam (MNM) chief asked the centre not to renege on promises made to states when India was made a republic and warned the Narendra Modi government of a language war that "India or Tamil Nadu doesn't need or deserve".
