The Bharatiya Janata Party won a decisive majority in the West Bengal assembly elections, capturing 206 of 294 seats and forming its first government in the state. The victory marks the end of the Trinamool Congress's 15-year rule, with Chief Minister Mamata Banerjee defeated in the Bhabanipur constituency by BJP leader Suvendu Adhikari.

This is the first time since 1972 that West Bengal will be governed by a party that also holds power at the Centre, aligning state administration with the Union government under Prime Minister Narendra Modi. The BJP's vote share rose from 4% in 2011 to nearly 40% in 2019, and the party had previously emerged as the main opposition in the 2021 assembly polls with 77 seats.

The result completes the BJP's political consolidation across eastern India, extending its influence from Bihar and Odisha into West Bengal. With the party now in power in key eastern states, its 'double engine' governance model—promising faster development and coordinated policy—is expected to be implemented across the region.

Political observers say West Bengal's long-standing single-party dominance has given way to a more competitive, bipolar system. The Trinamool Congress has conceded defeat, and the Election Commission is expected to announce the swearing-in date for the new chief minister within the week.
