The President is the nominal head of India, but the real executive power sits with the Prime Minister and the Council of Ministers. This is one of the most reliable scoring areas in the NDA Polity paper. Get the Articles, the appointment process and the idea of collective responsibility right, and a handful of marks become almost guaranteed.
Why This Topic Wins You Marks
In the NDA General Studies (Polity) section, questions on the Union Executive appear almost every year. The Prime Minister and the Council of Ministers are favourites because the facts are crisp, factual and hard to confuse once you learn them properly.
Unlike abstract topics, here the examiner tests definitions, Articles and constitutional relationships. There is little room for interpretation, so a well-prepared candidate rarely loses these marks.
Always link a fact to its Article number. Many NDA questions are framed as “Which Article deals with...?” Memorising Articles 74 and 75 alone can fetch you two to three marks.
This page builds the topic from the ground up — the office, the appointment, the powers, the ministerial ranks and the principle that holds the whole system together: responsibility to the Lok Sabha.
The Parliamentary System: Real vs Nominal Head
India follows the parliamentary system of government, borrowed from the British model. In this system, the executive is divided into two parts.
- Nominal (de jure) head – the President, who is the formal head of State.
- Real (de facto) head – the Prime Minister, who heads the actual working government.
The President exercises powers on the advice of the Council of Ministers headed by the PM. So while orders are issued in the President’s name, the decisions are taken by the PM and his ministers.
India is a parliamentary democracy, not a presidential one. The executive (PM and Council) is responsible to the legislature (the Lok Sabha) and not independent of it.
This responsibility is the dividing line between the Indian and the American (presidential) systems — a very common NDA comparison question.
Appointment of the Prime Minister
Article 75 simply says the Prime Minister shall be appointed by the President. The Constitution lays down no specific procedure for selecting the PM — this is governed by convention.
The convention
By established practice, the President appoints the leader of the majority party (or coalition) in the Lok Sabha as the Prime Minister. When no party has a clear majority, the President uses personal discretion but normally invites the largest party or pre-poll alliance to prove its majority on the floor of the House.
A person who is not a member of either House can be appointed PM, but must get elected to Parliament within six months, failing which they cease to hold office.
Which House?
The PM may be a member of the Lok Sabha or the Rajya Sabha. There is no constitutional bar on a Rajya Sabha member becoming PM — several have, including in recent decades.
Powers and Functions of the Prime Minister
The PM is the linchpin of the government. Powers can be grouped under a few heads.
In relation to the Council of Ministers
- Recommends the names of ministers to be appointed by the President.
- Allocates and reshuffles portfolios among ministers.
- Can ask a minister to resign or advise the President to dismiss one.
- Presides over Cabinet meetings and guides its decisions.
In relation to the President
- Acts as the principal channel of communication between the President and the Council of Ministers.
- Advises the President on appointments of key officials such as the Attorney General, CAG, UPSC Chairman, Election Commissioners, etc.
In relation to Parliament
- Advises the President on dissolution of the Lok Sabha.
- Announces government policies on the floor of the House.
The PM is the leader of the Council of Ministers, the leader of the Lok Sabha (usually), and the head of the ruling party — making the office immensely powerful in practice.
Articles 74 and 75: The Backbone
Two Articles define the Council of Ministers. Memorise them word-perfect.
- Article 74 – There shall be a Council of Ministers with the PM at the head to aid and advise the President, who shall act in accordance with such advice.
- Article 75 – Deals with appointment, tenure, responsibility, oath and salaries of ministers.
The advice is binding
The 42nd Amendment (1976) made the President’s acting on ministerial advice binding. The 44th Amendment (1978) allowed the President to send the advice back once for reconsideration — but if the Council sends it again, the President must accept it.
Students wrongly think the President can reject ministerial advice outright. After the 44th Amendment, the President can only ask for one reconsideration; the final advice is binding.
Article 74 also clarifies that the question of whether any advice was given by ministers to the President cannot be enquired into by any court.
Three Categories of Ministers
The Council of Ministers is not a single flat group. It has a clear hierarchy, and confusing these is a classic NDA trap.
1. Cabinet Ministers
The top rank. They head important ministries such as Home, Defence, Finance and External Affairs. They attend Cabinet meetings and shape national policy.
2. Ministers of State (MoS)
Either hold independent charge of a ministry/department, or are attached to a Cabinet Minister. They do not normally attend Cabinet meetings unless specially invited.
3. Deputy Ministers
The lowest rank. They are not given independent charge; they assist Cabinet Ministers or Ministers of State in their administrative and parliamentary work.
The Council of Ministers (all three ranks) is the wider body. The Cabinet is the smaller, inner core of senior ministers that actually takes the big decisions. The Cabinet is a part of the Council, not the other way round.
Council of Ministers vs Cabinet
This distinction is asked again and again. Keep the comparison sharp.
- The Council of Ministers is a constitutional body (Articles 74, 75) consisting of all ministers of every rank, usually 60-70 members.
- The Cabinet is a smaller group of senior-most ministers. The word “Cabinet” was inserted into the Constitution by the 44th Amendment (Article 352) but the Cabinet’s functions are not detailed by the Constitution.
The full Council of Ministers rarely meets as a body. Real decision-making happens in the Cabinet, which directs and controls the government.
91st Amendment limit
The 91st Amendment (2003) capped the size of the Council of Ministers: the total number of ministers, including the PM, shall not exceed 15% of the total strength of the Lok Sabha (for States, the limit is 15% of the State Assembly, with a minimum of 12).
Collective and Individual Responsibility
This is the soul of the parliamentary system and a guaranteed NDA topic.
Collective responsibility (Article 75)
The Council of Ministers is collectively responsible to the Lok Sabha. This means:
- All ministers swim and sink together — a decision of the Cabinet binds every minister.
- If the Lok Sabha passes a no-confidence motion, the entire Council (including ministers who are in the Rajya Sabha) must resign.
- A minister who disagrees with a Cabinet decision must either accept it publicly or resign.
Individual responsibility (Article 75)
Ministers hold office during the pleasure of the President. On the PM’s advice, the President can drop an individual minister without affecting the rest of the Council.
The Council is responsible to the Lok Sabha only, not the Rajya Sabha. A no-confidence motion can be moved only in the Lok Sabha. Do not say “Parliament” loosely in the answer.
Worked Example: Tracing a Government's Fall
Let us walk through how these rules play out, the way an NDA application question might frame it.
A government is in power. The Lok Sabha has 543 members. The Opposition moves a no-confidence motion. Trace what must happen and check the legal maximum size of the ministry.
So the answer to “maximum ministers” is 81, and the consequence of the motion is the resignation of the whole Council, not just the PM.
For any “15% of Lok Sabha” sum, always round down — you cannot have a fraction of a minister.
Oath, Tenure and Salary of Ministers
A few crisp facts that examiners love because they are easy to set as one-liners.
- Oath: Ministers take the oath of office and secrecy, administered by the President.
- Tenure: Ministers hold office during the pleasure of the President — meaning, in practice, as long as the PM wants them.
- Salary: Salaries and allowances of ministers are determined by Parliament from time to time.
- Qualification: A minister must be a member of either House of Parliament. A non-member can be appointed but must become an MP within six months.
The oath of secrecy reflects collective responsibility — ministers cannot reveal Cabinet discussions. This is why the President administers it personally.
Previous-Year Style Question
Here is the kind of question you should expect in the NDA paper, with the reasoning spelt out.
Q. Consider the following statements about the Council of Ministers in India:
1. It is collectively responsible to both Houses of Parliament.
2. The Prime Minister is appointed by the President.
3. The total number of ministers, including the PM, cannot exceed 15% of the strength of the Lok Sabha.
Which of the above statements is/are correct?
Answer: Statements 2 and 3 are correct. Statement 1 is wrong — the Council is collectively responsible to the Lok Sabha only, not both Houses. The 15% ceiling (statement 3) comes from the 91st Amendment, and the President appoints the PM under Article 75 (statement 2).
In “which statements are correct” questions, the trap is almost always the word “both Houses” or “Parliament” where it should read “Lok Sabha”. Read every option for that single misleading word.
