In an exclusive townhall with NDTV, Delhi Chief Minister Arvind Kejriwal slammed Lieutenant Governor VK Saxena for stopping public yoga classes in the national capital. "17,000 people used to take yoga classes. The LG one day called the file and stopped yoga classes. Is this a right thing to do? I begged with him to not stop yoga classes, but he didn't listen. Who stops yoga? It's a sin," Mr Kejriwal said.
