Mamata Banerjee’s political career had long been defined by her unyielding grip on West Bengal, where she served as Chief Minister for 15 years. Her party, the Trinamool Congress (TMC), seemed invincible, bolstered by a loyal voter base and a series of populist policies. However, the 2026 West Bengal elections revealed a different narrative as the Bharatiya Janata Party (BJP) made substantial electoral gains.
In a decisive turn of events, the BJP won 44 seats and was leading in 160 of the 294 seats. Meanwhile, Banerjee’s TMC secured only 21 seats and was leading in 62 seats. This shift not only challenged her authority but also marked a potential reconfiguration of West Bengal’s political landscape.
The campaign leading up to these elections saw Banerjee at her most active—she addressed a record 90 rallies and led 22 roadshows in just two months. Yet, despite her fervent efforts, allegations of corruption and anti-incumbency sentiments loomed large. “I am the candidate from all seats,” she proclaimed defiantly, yet it seemed her words fell on increasingly deaf ears.
The electoral roll revision played a critical role in this election. An intensive revision removed approximately 9.1 million names, including 6.3 million dead and absentee voters. This move raised eyebrows and questions regarding its impact on voter turnout and party support. Some experts argue that this could have disproportionately affected TMC’s traditional voter base.
The BJP capitalized on this environment by implementing strategic measures to mobilize voters. They arranged trains for around 2.2 million migrant workers, ensuring they could return home to vote. The party’s campaign resonated with various demographics, including women voters—once staunch supporters of Banerjee—who appeared to have shifted their allegiance this time around.
Banerjee tried to counteract religious polarization by building a Jagannath temple at a cost of ₹250 crore, but critics accused her of appeasing Muslims through financial allowances for Imams and Muezzins—₹2,500 and ₹1,500 monthly, respectively. The BJP seized on these narratives to paint her administration as corrupt and out of touch with the electorate.
The atmosphere during the campaign was charged; chants of “Chor, chor (thief)” echoed from BJP supporters while TMC loyalists rallied behind slogans like “Kespur hobe CPM er sespur”—a nod to Banerjee’s roots in anti-Left activism. Yet, it became increasingly clear that the tides were turning.
The fallout from these elections has left many wondering about the future of Banerjee’s leadership and the TMC’s role in West Bengal politics. As she grapples with this unexpected defeat, experts anticipate that changes within her party may be necessary to regain lost ground before future contests.
