The president of India is the head of state.
He uses only nominal power. He’s not directly tagged by the public.
A member of congress, and a member of state, or MLA, elects him. Campaigners running for chairman must win a maturity of votes to win the election. This allows the chairman to be seen as representing the whole country.
The President oversees the general functions of all political institutions in the country and ensures that they work in harmony to achieve public objects.
He exercises the following powers
(i) All government work is done on behalf of the president.
(ii) All government laws and major policy opinions are made in his name.
(iii) All major movables are made on behalf of the President. These include the appointment of Chief Justice of India, judges of the Supreme Court and High Court, state governments, election officers, and ministers of other countries.
(iv) All transnational covenants and agreements were met by the President. The President is the Commander-in-Chief of the Indian Defense Forces.
Still, the President exercises all these powers only on the advice of the Council of Ministers.
The chairman can ask the Council of Ministers to review his advice. But if the same advice is given again, he’s obliged to act on it. Also, a bill passed by Congress won’t come until it’s approved by the President.
Still, he can delay this for a while and shoot the bill back to Congress for re-deliberations, If the chairman so solicits.
But if congress passes the bill again, he needs to subscribe to it.
Final answer:The President of India is elected by the members of the parliament. All government work is done on behalf of the president, he uses only nominal power, the president exercises his power only on advice of the council of ministers and the president oversees work done by the political institution.
