It is important to understand the constitutional rules which govern the office of the Prime Minister before you try to memorise the names and dates. Questions concerning Articles 74, 75, and 78 often appear in the SSC CGL, CDS, and State PCS exams.
Explanation of Articles 74 and 75 (Regarding Powers, Appointment, and Responsibilities)
The Indian Constitution establishes a parliamentary form of government inspired by the British Westminster model, with executive authority being divided between two separate offices:
- The constitutional and nominal head of state is the President of India; the various executive actions of the Union Government are officially carried out in the President's name.
- The de facto head of state (the real head): the Prime Minister is the actual head of the executive; he leads the Union Council of Ministers and exercises the genuine power of government.
Article 74(1) provides that there should be a Council of Ministers with the Prime Minister at its head to assist and advise the President, who, in carrying out his duties, is to act on the basis of that advice. The 42nd Constitutional Amendment Act of 1976 made the President bound by that advice. The 44th Constitutional Amendment Act of 1978 contained a provision allowing the President to request the Council of Ministers to reconsider its advice once, although he then had to accept the advice after such reconsideration.
Article 75 lays down the rules regarding appointment, term of office and responsibility:
- Article 75(1) — Appointment: The Prime Minister is appointed by the President of India and the other ministers are appointed by the President on the advice of the Prime Minister.
- Discretionary Power of the President: If one political party secures an absolute majority in the Lok Sabha, the President has no choice but to appoint the leader that the party has nominated. In the case where no party attains a clear majority (resulting in a hung parliament) or when an incumbent dies suddenly and there is no obvious successor, the President exercises his personal discretion in appointing the person most likely to secure a majority of votes in the House.
- Article 75(2) — Pleasure of the President: The ministers serve at the pleasure of the President. In practice, this means that the Prime Minister can request the President to dismiss any minister.
- Article 75(3) — Collective Responsibility: The Council of Ministers is collectively responsible to the Lok Sabha (the House of the People). If the Lok Sabha passes a Vote of No-Confidence against the government, the whole Ministry, including the Prime Minister, must resign.
- Article 75(5) — Six-Month Membership Rule: A minister who is not a member of either House of Parliament for a continuous period of six months ceases to be a minister. A person who is not a member of Parliament can be appointed Prime Minister, but must win election to either the Lok Sabha or the Rajya Sabha within six consecutive months.
Article 78: Relationship Between the President and Prime Minister
Article 78 defines the constitutional duties of the Prime Minister toward the President:
- To communicate to the President all decisions of the Council of Ministers relating to the administration of the affairs of the Union and proposals for legislation.
- To furnish such information relating to the administration of the affairs of the Union and proposals for legislation as the President may call for.
- If the President so requires, to submit for the consideration of the Council of Ministers any matter on which a decision has been taken by an individual minister but which has not been considered by the Council.
Qualifications, Oath, and Tenure
Eligibility & Minimum Age: The Constitution does not list qualifications specifically for the Prime Minister. Instead, the Prime Minister must qualify as a Member of Parliament. If the individual belongs to the Lok Sabha, the minimum age is 25 years. If the individual belongs to the Rajya Sabha, the minimum age is 30 years. The candidate must be a citizen of India and hold no office of profit under the government.
Oath of Office and Secrecy: Administered by the President of India in accordance with the Third Schedule of the Constitution. The Prime Minister swears two separate oaths: the Oath of Office and the Oath of Secrecy.
Tenure of Office: The term of the Prime Minister is not fixed by the Constitution. The Prime Minister holds office during the pleasure of the President. The President cannot dismiss a Prime Minister who retains the confidence of the majority in the Lok Sabha. The normal legislative term of the Lok Sabha is five years, but the government can fall earlier if it loses a floor test.

SECTION 5: High-Probability Repeated Traps (Layer 2 & 3)
The examination boards often set questions which are based on specific leadership patterns, and in order to avoid falling victim to the common pitfalls it is necessary to go through these historical classifications:
1. The prime ministers are appointed by means of selection from the Rajya Sabha (known as the 'Big Four').
The Prime Minister is generally considered to be leading from the Lok Sabha, but the Constitution also provides for a member of either house of Parliament to act as Prime Minister, and in the cases where appointments were made four of the people were members of the Rajya Sabha.
2. Chief Ministers Who Later Became Prime Minister (The Six Leaders)
One usually acquires experience in dealing with state governments before attaining the post of national leader. The six former Indian Prime Ministers who had previously served as Chief Minister of their home states are listed below:
Plaintext
3. Prime Ministers Who Died in Office
Three Prime Ministers died while actively serving in office, all belonging to the Indian National Congress:
- Jawaharlal Nehru had a stroke and died in New Delhi on the 27th of May 1964.
- Lal Bahadur Shastri died in Tashkent, which is now part of Uzbekistan but was then part of the USSR, and he is the only Indian Prime Minister to have died outside the country.
- Indira Gandhi was murdered by her bodyguards at their official residence in New Delhi on 31 October 1984.
Regarding Rajiv Gandhi: he was assassinated in Sriperumbudur, in Tamil Nadu, on 21 May 1991; at the time of his death he was an opposition leader and a former Prime Minister, not the Prime Minister who was in office at that time; Chandra Shekhar was acting Prime Minister in May 1991.
4. The key historical events associated with the terms of the prime minister
Examinations frequently link major historical events to the Prime Minister in office at the time:
The Tashkent Declaration, signed on 10 January 1966, was the result of negotiations mediated by the Soviet Premier Alexei Kosygin and saw India's Prime Minister Lal Bahadur Shastri and Pakistan's President Muhammad Ayub Khan signing it, thus marking the official conclusion of the war between India and Pakistan in 1965; Shastri died the next morning.
As a result of the Shimla Agreement—the agreement which was signed on 2 July 1972 by Indian Prime Minister Indira Gandhi and Pakistani President Zulfikar Ali Bhutto after the Bangladesh Liberation War in 1971—the Line of Control (LoC) was established.
Pokhran-I vs Pokhran-II Nuclear Tests:India's first successful nuclear test, the Pokhran-I experiment (referred to as Smiling Buddha), took place at the Pokhran test site in Rajasthan on 18 May 1974 and was carried out under the direction of Indira Gandhi.
The five underground nuclear explosions carried out during Pokhran-II (referred to as Operation Shakti) occurred on 11th and 13th May 1998 and were directed by Atal Bihari Vajpayee, thereby establishing India's position as a nuclear-armed state.
In June 1991, when a serious foreign exchange balance-of-payments crisis arose, Prime Minister P.V. Narasimha Rao and Finance Minister Dr. Manmohan Singh launched a series of structural economic reforms called Liberalization, Privatization and Globalization (LPG); these reforms involved the abolition of the License Raj, a devaluation of the rupee and the opening of the economy to foreign direct investment.
5. The prime minister is the chairman.
By virtue of office, the Prime Minister serves as the chairperson of several key national statutory and policy bodies:
- The Prime Minister has taken over the role of Chairperson of the NITI Aayog (National Institution for Transforming India) since 1 January 2015.
- The Prime Minister chairs the National Integration Council, whose objective is to deal with communalism, casteism, and regionalism.
- The Inter-State Council was set up under Article 263 of the Constitution with the aim of promoting coordination between the Union and the states and is chaired by the Prime Minister.
- The National Disaster Management Authority (NDMA) was established by the Disaster Management Act of 2005 and is headed by the Prime Minister.
- The Nuclear Command Authority (NCA) is structured so that the Prime Minister leads the Political Council, this council being the only one permitted to order the retaliatory use of nuclear weapons.
- As long as the Department of Space and the Department of Atomic Energy are not placed under a separate Cabinet Minister, they will continue to be directly responsible to the Prime Minister.

🤖 AI-Based Weak Area Recommendation
Personalized DiagnosticsTaking practice exams without reviewing the mistakes you have made will result in you making the same errors on the day of the actual exam; just as a specialised personal tutor, the automated AI diagnostic tool on our testing platform operates.
Here is how the analysis works:
- Once you have finished taking a practice test that contains either 50 or 100 questions, you then submit your answers.
- The engine maintains a record of whether each question is answered correctly, incorrectly, or not answered at all for all three layers.
- The dashboard will display those topics in red if you get the questions about Rajya Sabha appointments, acting Prime Ministers, or economic reform dates wrong, even if you have answered the general constitutional questions correctly.
- The system gives you an automatic suggestion regarding your studies: as your accuracy fell below 50% in the area of Prime Ministerial Chronology and Landmark Foreign Treaties, you should look over our notes on the Tashkent Agreement and the four Prime Ministers of the Rajya Sabha, and then do our 15-question focused drill before taking your next full mock test.

SECTION 7: 15 Common Mistakes Students Make While Preparing Prime Ministers GK
Avoid these frequent preparation errors to protect your score:
- Taking the head of state for the head of government: confusing the President's nominal executive power (de jure) with the Prime Minister's real executive power (de facto).
- It should not be overlooked that a member of the Rajya Sabha can be appointed Prime Minister, as was the case with Indira Gandhi, H.D. Deve Gowda, I.K. Gujral and Dr. Manmohan Singh.
- If Rajiv Gandhi had died while in office, one might easily forget that at the time of his assassination in 1991 he was an opposition leader and a former Prime Minister, not the Prime Minister who was in office then.
- Confusing Morarji Desai with Charan Singh would be doing so by taking Morarji Desai—who was the first prime minister not from the Congress party and also the oldest prime minister—for Chaudhary Charan Singh, who was the only prime minister who never had to appear before Parliament.
- The mistake of confusing Pokhran-I with Pokhran-II lies in the fact that Pokhran-I took place in 1974 while Indira Gandhi was Prime Minister, whereas Pokhran-II happened in 1998 when Atal Bihari Vajpayee was in office.
- The notion that the Constitution specifies a five-year term for the Prime Minister is incorrect since the Prime Minister's term is not fixed by the Constitution and they remain in office as long as they retain the support of a majority in the Lok Sabha.
- Not considering the six-month membership period—the fact that a non-MP can serve as Prime Minister as long as they are elected to either the Lok Sabha or the Rajya Sabha within six consecutive months.
- The error that arises from considering the Prime Minister's role as specified in Article 78 to be optional is that the duty to inform the President of cabinet decisions is a constitutional obligation on the part of the Prime Minister and not just a customary practice.
- It is important to understand that Gulzarilal Nanda was never appointed as permanent Prime Minister, his role being merely that of Acting Prime Minister on two occasions, for 13 days each time.
- Misidentifying the 1966 Tashkent Declaration, which was signed by Lal Bahadur Shastri, with the 1972 Shimla Agreement, which was signed by Indira Gandhi.
- The notion that the Prime Minister chairs the National Development Council on their own overlooks the fact that the Prime Minister also serves as ex-officio chairman of NITI Aayog, the Inter-State Council, the NDMA, and the Nuclear Command Authority.
- If V.P. Singh had resigned voluntarily, then the fact that he was the first Prime Minister to be dismissed from office by means of a formal vote of no-confidence in the Lok Sabha in 1990 is ignored.
- The reason the 91st Constitutional Amendment has been overlooked is that it established the Council of Ministers at 15% of the total number of members of the Lok Sabha, including the Prime Minister.
- To look at a chronology without having an understanding of the historical context is to remember the names in order without knowing the economic policies, the wars, or the constitutional amendments connected with each term.
- Doing practice tests without keeping an error logbook in which to record and correct mistakes that occur repeatedly.
