There are six important functions of the Prime Minister of India. These are:

1. Formation of Ministry

2. Distribution of Portfolios

3. Chairman of the Cabinet Committee

4. Chief Co-ordinator of Policies

5. Sole Adviser to the President

6. Leader of the Nation

1. Formation of the Ministry:

The Ministry is formed by the Prime Minister. With the appointment of the Prime Minister, the President's vital role is completed, as it is now up to the Prime Minister to select his Ministers and deliver a list to the President. The President has no choice but to appoint the Ministers proposed by the Prime Minister.

The Prime Minister, as it is properly stated, "is important to its (Ministry's) formation, central to its life, and central to its death." The Prime Minister has the authority to choose his Cabinet members. If the Prime Minister resigns, the entire Ministry resigns as well. The Council of Ministers will be abolished when the Prime Minister dies. The Prime Minister has the authority to remove members of the Council of Ministers at any moment by requesting their resignation or having them fired by the President.

2. Distribution of Portfolios:

Another key role of the Prime Minister is portfolio distribution. He has complete control over the departments that his colleagues are assigned to. It is up to him to decide on the size of the Cabinet and the Ministers who will serve in it. If he believes a person is qualified for a position, he may choose ministers from outside the rank. He is to ensure that important members of the party receive crucial portfolios while dispersing portfolios. Ministers are chosen from all sections of the country in a federal state like India.

Furthermore, there may be some candidates for key portfolios such as Home, Defense, or Finance. In dispersing the portfolios, he must promote harmony and satisfaction to all parties. His work is indeed challenging. "His work is like that of making a figure out of blocks that are too numerous for the purpose and are not of shapes that fit properly together," Lowell says.

3. Chairman of the Cabinet Committee:

The Cabinet Committee is chaired by the Prime Minister. He convenes and preside over all Cabinet meetings. He is in charge of creating the agenda for such a meeting.

The Prime Minister may issue warnings, provide advise, or encourage them in the performance of their duties. He is the Council of Ministers' chairman. He serves as the Chairman of the Cabinet's several standing and ad hoc Committees.

4. Chief Coordinator of Policies:

The Prime Minister is the principal coordinator of numerous Departments' policies. In the event of a quarrel between two departments, he serves as a mediator. He mediates disputes between various Ministers and departments. He monitors the operations of all Departments of the Government of India. He can request any file from any Ministry for his review.

When it comes to the nomination of Governors and other high federal officers, the Prime Minister's voice takes precedence over the voices of the other Ministers. He is continually on the lookout for how critical ministries such as Finance, Foreign Affairs, and Home are operating. He also maintains regular contact with foreign embassies and represents the Union Government at Heads of State and Government Conferences.

5. Sole Adviser to the President:

The Prime Minister is the President's sole adviser. The Prime Minister has the authority to recommend the dissolution of the Lok Sabha. The President is expected to follow the Prime Minister's advise rather than that of other Ministers.

The Prime Minister serves as the sole point of contact between the President and the Cabinet. He reports to the President on all Cabinet decisions. If the President does not accept the Prime Minister's advice, the Prime Minister may resign. The Prime Minister's resignation will make it harder for the President to establish a successor Ministry.

It is difficult for the President to fire the Prime Minister as long as the majority of Lok Sabha members trust him.

6. Leader of the Nation:

The Prime Minister is the nation's leader. He is the Parliament's principal spokesman for government policies. He makes all significant policy announcements in Parliament. He is the majority party's leader, and as such, he is usually elected Speaker of the House.

The Prime Minister is expected to be a member of the House of Commons of the United Kingdom. In India, such a convention is projected to emerge in which the Prime Minister will be a member of the Lok Sabha, the country's most popular House.
