In a landmark election, the Bharatiya Janata Party (BJP) secured 206 out of 293 Assembly seats in West Bengal, effectively ending the 15-year rule of the All India Trinamool Congress (TMC) led by Mamata Banerjee. The BJP's vote share surged to 45.8%, a significant increase from just 4.06% in the 2011 elections, reflecting a major realignment of voter preferences in the state. The TMC, which previously dominated with 184 seats in 2011, saw its representation drop to 80 seats. Notably, Banerjee lost her own constituency, Bhabanipur, to BJP leader Suvendu Adhikari. The election also marked a historic voter turnout, with 92.8% in the first phase and 91.47% in the second phase, the highest since India's independence. The BJP's rise was particularly pronounced in North Bengal, where it made significant gains in constituencies that were once TMC strongholds. This election not only highlighted the BJP's transformation from a marginal player to the principal opposition force but also underscored the decline of traditional parties like the Communist Party of India (Marxist) and the Congress, which saw their vote shares plummet. The results indicate a growing polarization in West Bengal's political landscape, now largely dominated by the BJP and TMC.
