The Bharatiya Janata Party (BJP) crossed the majority mark [1] in the West Bengal assembly election on Monday, defeating the incumbent government.

This result marks a historic shift in the political landscape of West Bengal, ending the tenure of Chief Minister Mamata Banerjee of the Trinamool Congress (TMC) in one of India's most contested states.

The BJP victory was described as a landslide that indicates a strong shift in voter preferences [1, 2]. The results, which were announced live on May 4, 2026 [2], show the party securing enough seats to form a government independently.

Chief Minister Mamata Banerjee (TMC) challenged the legitimacy of the outcome. She said there was a "grave conspiracy" [3] to flood the voter rolls with outsiders to influence the result.

The impact of the BJP surge was evident across various constituencies. In one instance, Manas Bhunia, a seven-time MLA [2], trailed a BJP candidate as the results were tallied.

The victory follows a period of intense political friction between the TMC and the BJP. While the BJP attributes the win to a successful playbook and voter alignment, Banerjee said the manipulation of voter rolls aided the BJP's success [3, 4].

The final tally confirmed the BJP's control of the assembly by 11:24 a.m. [2]. This outcome represents a significant blow to the TMC's long-standing dominance in the region.

“The BJP crossed the majority mark in the West Bengal assembly election”

The BJP's majority in West Bengal signifies a breach of a long-term stronghold for the Trinamool Congress. By securing a historic landslide, the BJP has effectively expanded its influence in Eastern India, though the victory is clouded by allegations of voter-roll manipulation that may lead to legal challenges or prolonged political instability.
