Against the backdrop of JNU violence, NCP-chief Sharad Pawar said the BJP-led central government is using "dictatorial" policies which need to be answered through the non-violent way of Mahatma Gandhi. He was speaking after flagging of the 'Gandhi Shanti Yatra' of former-Union-minister Yashwant Sinha in the city, where former Maharashtra chief minister and Congress leader Prithviraj Chavan and state-minister Nawab Malik were present.
