1. Introduction — Who is the Prime Minister?
India follows the Westminster model of parliamentary democracy borrowed from Britain. In this system, the President is the constitutional head (nominal/formal executive) while the Prime Minister is the real executive — the actual centre of political power in the country.
Dr. B.R. Ambedkar called the Prime Minister the "linchpin of the Constitution" — without the PM, the entire constitutional machinery cannot function. The Council of Ministers headed by the PM is collectively responsible to the Lok Sabha and runs the government on a day-to-day basis.
2. Constitutional Provisions — Articles 74 to 78
The Prime Minister's office and powers are governed by Articles 74 to 78 of the Indian Constitution:
| Article | Provision | Key Point |
|---|---|---|
| Article 74 | Council of Ministers to aid and advise President | President shall act on advice of CoM (42nd Amendment made binding). PM heads this Council. |
| Article 75 | Appointment and tenure of Ministers | PM appointed by President. Other ministers appointed by President on PM's advice. Ministers hold office during pleasure of President. |
| Article 76 | Attorney General of India | Appointed by President on PM's advice. Not directly about PM but related to executive appointments. |
| Article 77 | Conduct of business of the Government of India | All executive actions of Government of India shall be expressed to be taken in the name of the President. |
| Article 78 | Duties of PM with respect to furnishing information to President | PM must: (a) communicate Cabinet decisions to President, (b) furnish information the President calls for, (c) submit for Cabinet consideration any matter on which a minister has decided but Cabinet has not considered. |
3. Appointment of Prime Minister
As per Article 75(1), the Prime Minister is appointed by the President. However, this is not an arbitrary appointment — the President must follow constitutional conventions:
The leader of the party or alliance that commands a majority (276+ seats) in the Lok Sabha is invited to form government. The President has no choice in this case.
When no single party has a clear majority, the President exercises discretion — inviting the single largest party or the leader who can demonstrate majority support.
The appointed PM must prove majority on the floor of the Lok Sabha within a stipulated time, usually 30 days, by winning a vote of confidence.
4. Qualifications for Prime Minister
The Constitution does not separately list qualifications for PM. Since the PM must be a member of Parliament, the qualifications are those required for Parliament membership:
- Citizen of India
- At least 25 years of age (Lok Sabha) or 30 years (Rajya Sabha)
- Member of either House of Parliament
- If not a member at time of appointment — must become one within 6 months
- Hold any office of profit under Government of India or any state
- Of unsound mind
- An undischarged insolvent
- Not a citizen of India or acquired citizenship of foreign country
5. Powers and Functions of the Prime Minister
The PM is the most powerful constitutional authority in India. Powers can be grouped into five major categories:
5.1 Powers in Relation to the Council of Ministers
5.2 Powers in Relation to the President
As per Article 78, the PM is the principal channel of communication between the President and the Cabinet. Specific duties include:
- Communicating all decisions of the Cabinet to the President
- Furnishing information the President calls for on administration and proposals for legislation
- Submitting to the Cabinet any matter on which a minister has acted but the Cabinet has not considered — if the President so requires
- Advising President on summoning and proroguing Parliament sessions
- Advising President on dissolution of the Lok Sabha
- Advising President on all major appointments (judges, CAG, Election Commissioners, etc.)
5.3 Powers in Relation to Parliament
- Leader of the House — the PM is the leader of the Lok Sabha (if a member of Lok Sabha)
- Announces government policies in Parliament
- Advises the President when to convene/prorogue Parliament sessions
- Can advise dissolution of Lok Sabha — though President can use discretion to refuse
- Manages the legislative agenda of the government
5.4 Powers as Chief Coordinator
- Coordinates the work of all ministries and departments
- Resolves inter-departmental disputes
- Chairs meetings of important committees including the Cabinet Committee on Security (CCS) — the most powerful committee, dealing with defence, nuclear weapons, and national security
- Chairs the NITI Aayog (replaced Planning Commission in 2015)
- Chairs the National Development Council
- Chairs the National Integration Council
5.5 Emergency Powers
- The President declares National Emergency (Article 352) only on written advice of the Cabinet — the PM heads this Cabinet
- In practice, the decision to recommend Emergency is that of the PM
- The PM is the political head during all types of emergencies
6. PM's Relationship with the President
| Aspect | President | Prime Minister |
|---|---|---|
| Nature of executive | Nominal / Constitutional / De jure | Real / Effective / De facto |
| Appointment | Elected by Electoral College (Art. 54) | Appointed by President (Art. 75) |
| Tenure | 5 years (fixed) | As long as Lok Sabha majority |
| Accountability | Not accountable to Parliament | Accountable to Lok Sabha |
| Source of power | Constitution | Lok Sabha majority |
| Article 78 | Can seek information from PM | Must communicate Cabinet decisions |
7. Removal of the Prime Minister
The PM can be removed from office in the following ways:
Most common method. If the Lok Sabha passes a no-confidence motion against the government by a simple majority, the PM and the entire Council of Ministers must resign. Example: V.P. Singh (1990), H.D. Deve Gowda (1997).
The PM may voluntarily resign. When the PM resigns, the entire Cabinet automatically ceases. Example: Atal Bihari Vajpayee resigned in 1999 after losing confidence motion by one vote — the closest ever margin.
If the PM is disqualified from Parliament (e.g., under anti-defection law or court order), they cease to hold the PM's office.
Three PMs have died in office: Jawaharlal Nehru (1964), Lal Bahadur Shastri (1966 — died in Tashkent), and Indira Gandhi (1984 — assassinated).

9. Important Committees Chaired by PM
10. Previous Year Questions — UPSC, JKSSB & JKPSC
Arranged from basic to advanced. Attempt each before reading the explanation.
Under Article 78 of the Constitution, it is the duty of the Prime Minister to:
(a) Furnish information to the President on matters related to administration
(b) Act as the link between the President and Council of Ministers
(c) Both (a) and (b)
(d) Neither (a) nor (b)
Article 78 lays down three duties of the PM: (1) Communicate all Cabinet decisions to the President, (2) Furnish information President calls for on administration and legislation proposals, (3) Submit any matter for Cabinet consideration if President requires it. Both statements are correct.
Consider the following statements about the Prime Minister of India:
1. The PM must be a member of the Lok Sabha.
2. All decisions of the Cabinet are communicated to the President by the PM.
Which of the statements given above is/are correct?
(a) 1 only (b) 2 only (c) Both 1 and 2 (d) Neither 1 nor 2
Statement 1 is incorrect — the PM need not be from Lok Sabha. The Constitution only requires the PM to be a member of either House of Parliament. H.D. Deve Gowda and I.K. Gujral were from Rajya Sabha. Manmohan Singh served two full terms as PM from Rajya Sabha.
Statement 2 is correct — this is the first duty under Article 78.
Who among the following described the Prime Minister as the "keystone of the Cabinet arch"?
(a) Dr. B.R. Ambedkar (b) Ivor Jennings (c) Granville Austin (d) H.J. Laski
British constitutional scholar Ivor Jennings described the PM as the "keystone of the Cabinet arch." Dr. Ambedkar called the PM the "linchpin of the Constitution." H.J. Laski described the PM's office as "the pivot around which constitutional machinery revolves." All three descriptions appear frequently in UPSC questions — memorise all three with their authors.
Which one of the following is NOT a function of the Prime Minister?
(a) Presides over the meetings of the Cabinet
(b) Advises the President on the appointment of important officials
(c) Communicates the decisions of the Cabinet to the President
(d) Nominates members of the Rajya Sabha
Nominating 12 members to the Rajya Sabha (under Article 80) is the President's power, exercised in their own discretion — not on PM's advice. It is one of the few genuine discretionary powers of the President. Options (a), (b), (c) are all genuine powers/functions of the PM.
Under which Article of the Indian Constitution is the Prime Minister appointed by the President?
(a) Article 74 (b) Article 75 (c) Article 76 (d) Article 78
Article 75(1) states: "The Prime Minister shall be appointed by the President and the other Ministers shall be appointed by the President on the advice of the Prime Minister." Article 74 deals with the Council of Ministers as a whole. Article 78 deals with PM's duties. Article 76 is about the Attorney General.
Who was the first Prime Minister of India from a non-Congress party?
(a) Atal Bihari Vajpayee (b) Morarji Desai (c) V.P. Singh (d) Charan Singh
Morarji Desai of the Janata Party became the first non-Congress PM in 1977 after the Janata Party won the general elections following the Emergency period (1975–77). He served till 1979. Vajpayee was the first BJP PM but came much later in 1996 (briefly) and then 1998–2004.
Which PM of India never faced Parliament during their tenure?
(a) Gulzarilal Nanda (b) Charan Singh (c) H.D. Deve Gowda (d) I.K. Gujral
Charan Singh became PM in July 1979 but resigned in August 1979 — before the Parliament could even meet. He is the only PM in Indian history who never addressed Parliament or faced it as Prime Minister. This is a very commonly asked fact in JKSSB.
Who chairs the NITI Aayog?
(a) President of India (b) Vice President (c) Prime Minister (d) Finance Minister
The PM is the ex-officio Chairperson of NITI Aayog (National Institution for Transforming India), which replaced the Planning Commission on January 1, 2015. The CEO of NITI Aayog is appointed by the PM. NITI Aayog is not a constitutional body — it was created by a Government of India resolution.
The 44th Constitutional Amendment Act, 1978 made which important change regarding Article 74?
(a) President can now reject Cabinet advice
(b) President can return advice for reconsideration once but must accept it the second time
(c) PM must seek President's approval before Cabinet decisions
(d) No change was made to Article 74
The 44th Amendment (1978) amended Article 74 to allow the President to send Cabinet advice back for reconsideration once — but the President is bound to act on the advice if it is sent again. Before the 42nd Amendment (1976), the President had more discretion. The 42nd Amendment made the word "shall" mandatory. The 44th Amendment balanced this by giving the President a one-time reconsideration power.
Which of the following is/are the discretionary power(s) of the President that the Prime Minister CANNOT influence?
1. Appointment of PM when no clear majority
2. Dissolving Lok Sabha when PM advises so
3. Nominating 12 members to Rajya Sabha
(a) 1 only (b) 1 and 3 (c) 2 and 3 (d) 1, 2, and 3
When there is no clear Lok Sabha majority, the President uses genuine discretion in choosing the PM — the PM cannot influence their own appointment in this scenario (1 is correct). Nominating 12 Rajya Sabha members is also genuinely discretionary (3 is correct). Dissolving Lok Sabha on PM's advice (2) is NOT discretionary in normal circumstances — the President generally must accept PM's advice on dissolution, though some scholars debate this when PM has lost majority.
Who among the following was described as "the Prime Minister as the linchpin of the Constitution"?
(a) Granville Austin (b) Ivor Jennings (c) B.R. Ambedkar (d) Jawaharlal Nehru
Dr. B.R. Ambedkar, the principal architect of the Constitution, used the phrase "linchpin of the Constitution" for the PM in the Constituent Assembly debates. Ivor Jennings used "keystone of the Cabinet arch." This question has appeared multiple times in UPSC and JKPSC — both quotes must be memorised with their exact authors.
