West Bengal’s Phase 2 assembly elections are scheduled for April 29, 2026, covering 142 of 294 constituencies. Phase 1 (April 23) covered 152 constituencies — primarily in North Bengal, Jhargram, tribal regions, and West Midnapore — and recorded a historic 93.19% voter turnout, the highest in West Bengal since Independence. Phase 2 covers the more densely populated Kolkata suburbs, Howrah, Hooghly, Burdwan, Birbhum, and parts of South Bengal — historically the most politically contested terrain. The Election Commission of India (ECI) has deployed over 800 central forces companies for Phase 2. The campaign period ended at 6 PM on April 28.

2026 West Bengal Election — Three-Cornered Contest

Alliance Key Party Leader Position
Trinamool Congress (TMC) TMC Mamata Banerjee (CM; contesting from Bhawanipur, Kolkata) Incumbent; seeking 3rd consecutive term
National Democratic Alliance (NDA) BJP Suvendu Adhikari (LoP; contesting from Nandigram) Main opposition
Left-Congress-ISF alliance CPI(M) + Congress + ISF Multiple leaders Third force; strong in some districts

Key constituency battles in Phase 2:

  • Bhawanipur (Kolkata) — Mamata Banerjee’s seat; symbolic battleground
  • Nandigram — Suvendu Adhikari’s seat; site of the 2021 mega-contest between Mamata and Suvendu
  • Birbhum — TMC’s stronghold; Anubrata Mondal factor
  • Burdwan-Durgapur — industrial corridor; BJP made gains in 2021

May 4 — All State Results Simultaneously

The Election Commission of India scheduled all 2026 state election results on May 4, 2026 — a single unified counting day for five state elections conducted across April:

State/UT Seats Polling Phase(s) Results
Tamil Nadu 234 April 23 (single phase) May 4
West Bengal 294 Phase 1: April 23; Phase 2: April 29 May 4
Kerala 140 April 9 (single phase) May 4
Assam 126 April 9 (single phase) May 4
Puducherry 30 (elected) April 9 (single phase) May 4
Total seats 824 — May 4

May 4 will be one of India’s largest simultaneous election result days — with 824 legislative assembly seats determined in a single counting session.

West Bengal 2021 vs 2026 — Context

Factor 2021 2026
TMC result 213 seats (72.4%) Polls ongoing
BJP result 77 seats (26.2%) Polls ongoing
Left+Congress 0 (zero) Left-Congress-ISF alliance with ISF
Mamata constituency Won Bhawanipur (by-election, Sept 2021) after Nandigram loss Contesting Bhawanipur
Suvendu constituency Won Nandigram (narrow margin) Re-contesting Nandigram

2026 context: TMC enters the election as a strong incumbent but has faced anti-incumbency narratives around corruption, governance delivery, and central-state tensions over scheme funding. BJP has maintained its 2021 base but has not significantly expanded it. The Left-Congress-ISF alliance is seeking to reclaim historic Left strongholds.
