Delhi's Ramlila Maidan and the places around it have been put under elaborate security measures where the Aam Aadmi Party will hold a "Maha Rally" on Sunday. Delhi chief minister Arvind Kejriwal since the last couple of months have been voicing out against the Centre's ordinance on control of services in the national capital. The Maha Rally becomes a crucial demonstration of dissent by AAP along with their supporters.
