Telugu Desam Party chief N Chandrababu Naidu on Thursday challenged the Y S Jagan Mohan Reddy government to conduct a referendum on the three capitals for the state plan. The former CM vowed to quit politics if people voted for it. He demanded that the CM apologise to the people and withdraw the move to relocate the state capital in deference to the wishes of six crore people of the state. Naidu addressed a massive rally in Amravati to mark the first anniversary of the farmers struggle for retaining Amaravati as the state capital.
