While KCR is trying to stitch a federal front, Chandrababu Naidu is trying to hold a meeting of opposition parties before 21st may. Naidu made a courtesy call to Rahul Gandhi in Delhi to make the request. Now the ball is in Rahul's court who will take the final call. Opposition parties may also shoot a letter to the president asking him not to invite the single largest party to form the government in case of a split verdict.
