Bhim Army chief Chandrashekhar Azad on Tuesday joined the agitating farmers who have been camping outside Delhi to press for their demand of repealing the Centre's farm laws. In an interview with NDTV, he said the outfit will extend support from "outside" while the protest will be led by farmers. Mr Azad, an emerging Dalit leader in Uttar Pradesh politics, slammed the Centre for using watercannons and tear gas on farmers marching to the national capital from Punjab last week, and said the government is "afraid" of the farmers' movement.
