Preparations are in full swing at the Ramlila Maidan for Chief Minister-designate Arvind Kejriwal's swearing-in ceremony on Saturday with a massive crowd expected to converge on the historic ground. A total of 76 CCTV cameras have been installed inside the ground and around its periphery to secure the venue. For visitors, nearly 40,000 seats have been put up, and arrangements for standing for about 20,000 more people have also been done.
