A combative YSR Congress Party chief Y S Jaganmohan Reddy on Saturday launched an indefinite fast against Centre's ‘arbitary’ decision to bifurcate Andhra Pradesh and said it will be challenged in Supreme Court. He said Sonia Gandhi is dividing Andhra Pradesh to make her son prime minister. I beg her with folded hands not to do divide a state for her petty political gains. I request her not to ignore the fact that people of Seemandhra are also Indians and their fundamental rights should be protected
