The position of Prime Minister is not elected straightly.
However, the President is unable to appoint anybody he desires.
As Prime Minister, he picks the leader of the dominant party or coalition of parties with a majority in the Lok Sabha.
If no single party or alliance achieves a majority, the President picks the person with the best chance of gaining majority support.
The Prime Minister’s term is not set in stone.
Because he is the leader of the government, the Prime Minister has broad powers:
He is in charge of overseeing many ministries and under his direction, all ministers work.
He has the authority to fire ministers and when the Prime Minister resigns, the entire cabinet resigns as well.
As a result, the Prime Minister is the Cabinet’s most powerful member.
The President of India picks a Prime Minister who is either the leader of the party with the most seats in the Lok Sabha or a person who can win the Lok Sabha’s confidence by winning support from other political parties.
