Social activist Anna Hazare and yoga guru Baba Ramdev will sit on a day-long fast in the national capital tomorrow as a mark of their protest against corruption and black money stashed away by Indians abroad. "The protest will take place in the capital at Jantar Mantar, in all state capitals and in 650 districts across the country," Baba Ramdev said at a press conference in Delhi yesterday. The yoga guru said he would be joined by Anna Hazare during his day-long hunger strike. Team Anna members Arvind Kejriwal, Manish Sisodia and Kiran Bedi will also participate in the protest.
