"Today the Governors in India are constitutional representatives. They are not some political parallel power centres. In our democracy, he is a ceremonial head," he said.
In his address at Raj Bhavan in Chennai after presiding over a book release event and dedicating a solar power plant, the Vice President said a Governor cannot "interfere" in the regular functioning of a government.
"In our democracy he (Governor) is a ceremonial head. Only the ministry has true powers. You have to understand the Governor's powers and limitations."
"Without knowing the governor's powers and limitations if you come with your own expectations and then get disappointed, nobody can help you," Mr Naidu said.
Mr Naidu said Mr Rao had discharged his responsibilities during his tenure to the 'maximum satisfaction of the Constitution.' "Some people may be happy, some people may be unhappy, but you cannot make everybody happy as you have to act as per the Constitution," Mr Naidu said.
During Mr Rao's stint in Tamil Nadu, the state witnessed a spate of political twists and turns following hospitalisation of then Chief Minister J Jayalalithaa on September 22, 2016, and her subsequent death in December last.
