Key Takeaways

After the shock defeat of the delimitation-cum-women's reservation bill on April 17, 2026, the BJP launched a high-stakes strategy to secure 360+ Lok Sabha seats — enough for a two-thirds majority — by engineering defections, targeting regional parties, and leveraging its historic Bengal win. The outcome will determine whether the government can reshape India's electoral map through constitutional reform.

  • BJP's Mission 360 aims to secure a two-thirds Lok Sabha majority to pass constitutional amendments on delimitation, women's reservation, and One Nation One Election
  • The Constitution (131st Amendment) Bill was defeated on April 17, 2026 — 298 for, 230 against, 54 short of the required 352 votes
  • NDA strength rose from 298 to 319 after 20 TMC MPs defected to NCPI and 6 Shiv Sena (UBT) MPs switched to the Shinde camp
  • BJP now needs 41 more MPs and is targeting SP (37), DMK (22), NCP-Sharad (8), and remaining TMC MPs
  • The West Bengal election landslide (BJP 206, TMC 81) in May 2026 provided political momentum and triggered defections
  • Suvendu Adhikari became Bengal's first BJP CM after defeating Mamata Banerjee in Bhabanipur by 15,105 votes
  • Two strategies: recruit 41 MPs through defections, OR reduce effective House strength by securing opposition absenteeism during voting
  • Congress alleges the real goal is to end reservations; Jairam Ramesh called it "todh-phod ki rajniti"

Evidence

The delimitation bill would have reduced southern states' parliamentary representation.

Supporting Evidence
  • Based on the 2011 census, southern states with better population control would see their share of Lok Sabha seats decline relative to northern states. Tamil Nadu's share would drop from 39 to approximately 31 seats if total seats increased to 850 proportionally.

The BJP's real goal in pursuing a two-thirds majority is to end reservation for SCs, STs, and OBCs.

Primary Sources: 1Evidence: 1 items
Supporting Evidence
  • While BJP leaders like Anantkumar Hegde have spoken about "changing the Constitution to save Hinduism," the party's official manifesto and public statements do not call for ending reservations. The party's stated goal is to pass women's reservation, delimitation, One Nation One Election, and judicial reforms — all requiring constitutional amendments.

The 20 TMC MPs who joined NCPI have legally merged with the NDA through a legitimate party merger.

Verified82%
Primary Sources: 1Evidence: 1 items
Supporting Evidence
  • The TMC MPs joined the Nationalist Citizens Party of India (NCPI), a Tripura-based registered unrecognised party, and then merged with the NDA. Under the anti-defection law, a merger of two-thirds of a party's MPs with another party is legal. The 20 MPs represent more than two-thirds of TMC's 29 Lok Sabha MPs.

The opposition united against the bill solely because of the delimitation clause, not women's reservation.

Verified85%
Primary Sources: 1Evidence: 1 items
Supporting Evidence
  • Multiple opposition leaders including Rahul Gandhi, MK Stalin, and Jairam Ramesh stated they support women's reservation but oppose the linkage to delimitation based on the 2011 census. Congress demanded implementing women's reservation on the existing 543 seats first.
