Prime Ministers of India — Complete List, Tenures & UPSC Quick Reference

Constitutional Basis

Exam tip: Article 74 makes ministerial advice binding on the President (after any reconsideration). Courts cannot inquire into what advice was tendered (Art. 74(2)).

Complete List of Prime Ministers of India (1947–Present)

India has had 14 individuals serve as Prime Minister. Gulzarilal Nanda served twice as interim/acting PM and is counted separately in sequential numbering, giving 15 PM tenures in total.

Note on numbering: When counting individuals only, India has had 14 PMs. When counting tenures (including re-appointments and Nanda's two stints), the count rises. Most UPSC sources call Modi the 14th Prime Minister.

PMs Who Died in Office or Were Assassinated

Deputy Prime Ministers of India (Complete List)

The office of Deputy Prime Minister is not mentioned in the Constitution — it is an extra-constitutional position. There have been 7 Deputy PMs since 1947. The post has been vacant since 22 May 2004.

Exam trap: Both Morarji Desai and Charan Singh served as Deputy PM before becoming PM themselves. Vallabhbhai Patel was the longest-serving Deputy PM and the first. The post has been vacant since May 2004.

Nehru–Gandhi Dynasty

Note: Rajiv Gandhi's surname "Gandhi" is coincidental — he was not related to Mahatma Gandhi. His wife Sonia Gandhi (née Maino) is Italian-born. Son Rahul Gandhi has not become PM as of April 2026.

PMs with Notable "Firsts" in Context

Exam Traps — Frequently Confused Facts

Tenure traps:

• Nehru = longest serving (~16 yrs 9 mo); Nanda = shortest (13 days, but only acting PM)
• Vajpayee = shortest among elected PMs with a substantive (non-interim) term (13 days, 1996 first term)
• Charan Singh = 170 days total as PM but actually resigned after 23 days and governed as caretaker; never faced Parliament
• Manmohan Singh's 10-year tenure (2004–2014) makes him the third-longest serving PM after Nehru and Indira Gandhi

Death/Assassination traps:

• Shastri died in Tashkent (USSR), not in India — cause of death officially cardiac arrest, but circumstances remain disputed
• Indira Gandhi assassinated by own bodyguards (Beant Singh and Satwant Singh), not by LTTE
• Rajiv Gandhi assassinated by LTTE, at Sriperumbudur, Tamil Nadu, but he was not PM at the time — he was former PM and Congress candidate

Party traps:

• Morarji Desai = Janata Party (not Congress), first non-Congress PM
• V.P. Singh = Janata Dal; Chandra Shekhar = Janata Dal (Socialist)/Samajwadi Janata Party; Deve Gowda and Gujral = Janata Dal — all distinct factions
• IK Gujral = Janata Dal, supported by Congress — not from Congress

Constituency traps:

• Manmohan Singh never won a Lok Sabha seat — only PM to serve entirely from Rajya Sabha
• Indira Gandhi's 2nd term constituency was Medak, Andhra Pradesh (not Rae Bareli; she lost Rae Bareli in 1977)
• Nehru's first seat: Phulpur (not Allahabad — he moved to Allahabad from 1957)

Other traps:

• Modi born 17 Sep 1950 — first PM born after Independence (15 Aug 1947). Every prior PM was born before 1947.
• Deputy PM post: not constitutional — no Article defines it; currently vacant since 2004
• Rajiv Gandhi ≠ relation of Mahatma Gandhi — different families entirely

Recent Developments (2024–2026)

PM Narendra Modi — Third Consecutive Term (June 2024)

PM Narendra Modi was sworn in for a third consecutive term on 9 June 2024 by President Droupadi Murmu at Rashtrapati Bhavan. He is the first Prime Minister since Jawaharlal Nehru to serve three consecutive terms in office. The BJP won 240 Lok Sabha seats — below the majority mark of 272 — making this the first time Modi's government is a genuine coalition, dependent on support from TDP (16 seats) and JD(U) (12 seats) among other NDA partners.

This coalition arithmetic directly tests Article 75(3) — collective responsibility of the Council of Ministers to the Lok Sabha — and Article 74(1), which requires the CoM to "aid and advise" the President. The cabinet size stands at 71 ministers, within the 15% constitutional cap (91st Amendment).

UPSC angle: Prelims — PM Modi third term, sworn in 9 June 2024; NDA coalition 293 seats. Mains — how does the 2024 coalition character affect collective responsibility conventions? Compare Modi 1.0 (2014), Modi 2.0 (2019), and Modi 3.0 (2024) in terms of executive strength.

PM Modi's Government — First One Nation One Election Bill Introduced (December 2024)

PM Modi's government introduced the Constitution (129th Amendment) Bill, 2024 in the Lok Sabha on 17 December 2024, implementing the Kovind Committee's recommendation for Simultaneous Elections (One Nation One Election). The Bill proposes synchronising Lok Sabha and State Assembly elections. It was referred to a Joint Parliamentary Committee. This is the most significant electoral constitutional reform proposed under PM Modi's tenure.

UPSC angle: Prelims — Constitution (129th Amendment) Bill, 2024; One Nation One Election; Kovind Committee Report submitted March 2024. Mains — assess the constitutional amendments required for ONOE; which articles need amendment and which conventions need change?

Coalition PM's Exercise of Article 78 — Cabinet Communications (2024–2026)

Article 78 requires the PM to communicate Cabinet decisions to the President and furnish information on request. In a coalition government, the PM's exercise of Article 78 is more publicly visible as major decisions require intra-coalition consultation. The Modi 3.0 government's first 100 days saw significant legislative and policy activity — including passage of Waqf Amendment Bill 2024, the first Budget with coalition partners' demands incorporated, and approval of ONOE recommendations.

UPSC angle: Prelims — Article 78 (PM's duties to President); no veto power by President over ministerial advice after reconsideration (Article 74). Mains — analyse the PM's constitutional role in coordinating between the coalition and the President in a multi-party government.
