The Bharatiya Janata Party (BJP) has formed the government in West Bengal after winning a clear majority in the 2026 Legislative Assembly election [1].
This victory marks a historic political shift in the region, ending the 15-year rule [2] of Mamata Banerjee and her Trinamool Congress (TMC) party. The result signals a significant change in leadership for one of India's most populous states.
The BJP secured more than 180 seats [1], crossing the majority threshold to take control of the assembly. The party successfully breached the TMC's stronghold in Kolkata and gained ground in key battlegrounds, including South Bengal and the Hooghly district [1].
The election took place in two phases on April 23, 2026, and April 29, 2026 [3]. Results were declared in late April 2026 following a campaign marked by clashes between TMC and BJP workers in areas such as Hooghly [3].
Analysis from The Quint attributed the BJP's success to five specific "M" factors: Machh (fish), Mahila (women), Machinery, Muslims, and the perceived shortcomings of Mamata Banerjee [2]. These elements are said to have collectively shifted voter sentiment away from the incumbent TMC government.
The transition follows a period of intense political rivalry in the state. By securing the majority, the BJP has displaced the long-standing administration of Banerjee, who had led the state since before the 2011 transition [2].
“The BJP secured more than 180 seats, crossing the majority threshold.”
The BJP's victory in West Bengal represents a major breach of a long-term regional stronghold. By overturning a 15-year incumbency, the BJP has demonstrated an ability to penetrate the TMC's urban and rural bases, potentially altering the political landscape of Eastern India and shifting the balance of power between regional and national parties.
