Powers and Functions of the Prime Minister

PM powers functions in India flow from the Prime Minister's position as the real, de facto executive under the parliamentary system, while the President remains the nominal, de jure executive. Article 75 provides only that the Prime Minister "shall be appointed by the President"; the Constitution does not lay down a detailed procedure or an exhaustive list of powers, and much of the office's authority has developed through convention built on top of this spare constitutional text.

Appointment and the Basis of Authority

By convention, the President appoints the leader of the majority party in the Lok Sabha as Prime Minister. When no party commands a clear majority, the President may exercise personal discretion in selecting a leader who appears capable of commanding the confidence of the House, and can require the newly appointed Prime Minister to prove that majority within a specified time. This convention-based, rather than procedure-based, mode of appointment is itself significant: the Prime Minister's authority ultimately rests on majority support in the Lok Sabha, not on any detailed constitutional formula.

Powers in Relation to the Council of Ministers

As head of the Council of Ministers, the Prime Minister:

• Recommends the appointment of other ministers to the President, and can advise their removal or reallocate portfolios.
• Presides over Cabinet meetings and coordinates the working of different ministries and departments.
• Makes the final call in case of disagreement between ministries or ministers.
• Supervises the ministries generally and holds the Council together as a working team.

Article 74(1) expressly places the Prime Minister "at the head" of the Council of Ministers. Because of this special position, the resignation or death of the Prime Minister automatically dissolves the entire Council — unlike the resignation or death of any other minister, which merely creates a single vacancy that the Prime Minister may or may not choose to fill. This has led commentators to describe the Prime Minister as the "keystone of the Cabinet arch," echoing the description used in Britain.

Powers in Relation to the President

The Prime Minister is the principal channel of communication between the Council of Ministers and the President. Article 78 makes this an explicit constitutional duty: the Prime Minister must

• communicate to the President all Council decisions relating to Union administration and legislative proposals;
• furnish any information relating to Union administration or proposed legislation that the President calls for; and
• if the President so requires, place before the Council for consideration any matter decided by an individual minister but not yet considered by the Council as a whole.

Because the President exercises virtually all executive, legislative, and other functions only on the aid and advice of the Council of Ministers headed by the Prime Minister — advice made explicitly binding by the 42nd Amendment (1976), subject to one round of reconsideration under the 44th Amendment (1978) — the Prime Minister effectively channels and shapes the exercise of presidential power at every stage.

Powers in Relation to Parliament

As leader of the majority party and of the House, the Prime Minister:

• Advises the President on summoning and proroguing sessions of Parliament.
• Can recommend dissolution of the Lok Sabha to the President before the expiry of its normal term, triggering fresh elections — a recognised feature of parliamentary government under which the executive can effectively get the legislature dissolved.
• Announces major government policies on the floor of the House and generally leads government business in Parliament.

Leadership Role

The Prime Minister simultaneously holds three overlapping leadership roles: leader of the Council of Ministers, leader of Parliament, and leader of the party (or coalition) in power. This combination is what gives the office its centrality — decisions on policy, legislative business, and party management all converge on the same individual, which is why, in practice, the working of the entire parliamentary system tends to revolve around the Prime Minister.

Historical Illustration

The evolving weight of the office is visible across India's political history. Jawaharlal Nehru's death in May 1964 was followed by Lal Bahadur Shastri's unanimous selection by Congress leaders; Shastri was known for accepting moral responsibility by resigning from the Railway Ministry after a railway accident. Indira Gandhi became Prime Minister in 1966 and, despite early expectations that she would remain dependent on senior party leaders, went on to consolidate control over the party within a year. These episodes illustrate how the office's real power has often depended as much on the incumbent's political standing within the ruling party as on the constitutional text itself.

Effect of Coalition Politics

While the position of the Prime Minister and Council of Ministers has generally been strongest when a single party secures a Lok Sabha majority, coalition governments — a recurring feature of Indian politics since 1989 — have tended to constrain this authority. Coalition arrangements require greater consultation among political partners, which can erode the degree of unilateral prime ministerial authority, even though the formal constitutional powers of the office remain unchanged.

UPSC Relevance

Prelims: Note the textual basis of PM powers: Article 74(1) (head of Council), Article 75(1) (appointment), Article 78 (duties towards the President) — and that the Constitution does not itself enumerate a detailed list of prime ministerial functions.

Mains: A recurring theme for essays on the "presidentialisation" of the Indian Prime Minister's office, the effect of coalition politics on prime ministerial authority, and comparisons with the British "prime ministerial government" debate.

FAQ

Does the Constitution list the Prime Minister's powers in detail? No. Article 75(1) only provides for the mode of appointment; most of the office's powers and functions have developed through convention.

What happens to the Council of Ministers if the Prime Minister resigns or dies? The entire Council of Ministers is automatically dissolved, unlike the resignation or death of any other individual minister, which creates only a single vacancy.

What is the Prime Minister's constitutional duty under Article 78? To keep the President informed of all Council of Ministers decisions on Union administration and legislative proposals, furnish information the President calls for, and place before the Council any matter the President wants reconsidered collectively.

Has coalition politics affected the Prime Minister's powers? The formal powers are unchanged, but coalition governments since 1989 have generally required greater consultation among partners, constraining how freely those powers can be exercised.
