West Bengal Assembly Elections 2026: As the state moves closer to the 2026 assembly elections, Banerjee faces one of the most consequential tests of her political career

West Bengal Assembly Elections 2026: Clad in a simple white sari and rubber slippers, Mamata Banerjee has long cultivated the image of an outsider in Indian politics. Over decades, that outsider has become one of the system’s most durable power centres, reshaping the political landscape of West Bengal and carving out a national role as a key opposition voice.

Her rise, as political analyst and historian Sanjay Kumar has often noted, is “a rare example of a leader who built power almost entirely from street mobilisation rather than institutional backing".

From Street Power To Power Centre

Banerjee’s early political career in the Indian National Congress was marked by agitation and visibility. She earned a reputation for taking on the then-dominant Left Front in West Bengal at a time when few dared to.

Her decision to leave the Congress in 1998 and form the All India Trinamool Congress was a gamble that would prove to be a defining moment not only for Banerjee’s career but also for the state.

According to multiple political observers, including scholars at the Centre for the Study of Developing Societies, Banerjee’s success lay in converting local grievances into a sustained political movement. The Singur and Nandigram protests against land acquisition became defining moments of her political career.

“These were not just protests, they were political turning points," a CSDS-based analyst noted. “Mamata Banerjee managed to turn agrarian anger into a regime-changing force."

In 2011, she ended 34 years of Left Front rule—an outcome that nobody had thought was probable.

Being ‘Didi’

Banerjee’s persona is central to her politics. Known simply as “Didi", she has built a direct emotional connection with voters.

Her image of personal austerity is not incidental, it is political. As political commentator Paranjoy Guha Thakurta has observed, “Her simplicity is her strongest political message. It creates a contrast with both elite politics and entrenched party structures."

At the same time, critics argue that her governance style is highly centralised, with power concentrated around her office.

Welfare, Identity, and Control

Banerjee’s model of governance combines welfare expansion with political messaging. Welfare schemes targeting women, minorities, and the rural poor have been key elements of Banerjee’s political strategy.

Data and field research cited by think tanks like CSDS indicate that these schemes have helped Banerjee command loyalty among voters.

“She has built what you might call a ‘welfare-backed political coalition’," said political scientist Milan Vaishnav. “It’s not just identity politics; it’s delivery plus identity."

National Ambitions

In recent times, Banerjee has emerged as one of the prominent critics of Prime Minister Narendra Modi and has established herself as a pivot for opposition politics.

Her efforts at forging a coalition against the BJP have not been entirely successful, but her assertiveness has ensured she continues to remain at the center of India’s political discourse.

“Mamata Banerjee represents a model of regional resistance to central dominance," said political analyst Suhas Palshikar. “But scaling that model nationally is far more complex."

Her party’s expansion efforts beyond West Bengal have so far yielded limited results, underlining the challenge of translating regional dominance into national influence.

This model helped her withstand the intense challenge posed by the Bharatiya Janata Party in the 2021 West Bengal elections, where she secured a decisive victory despite a high-voltage campaign.

Controversies And Criticism

Banerjee’s tenure has also been marked by persistent criticism. Her government has faced scrutiny over major corruption cases, most notably the school recruitment scam, which led to the arrest of senior leaders from the party, including former minister Partha Chatterjee.

Law and order have also been a recurring area of criticism. Incidents such as the Birbhum violence, where multiple people were killed following a local political clash, post-poll violence after the 2021 assembly elections, and the RG Kar case, have been cited by opponents as evidence of political intolerance and weak administrative control.

Banerjee has also faced accusations of curbing dissent. Critics, including sections of civil society and opposition parties, have pointed to cases where protests were restricted or where political opponents alleged intimidation.

Analysts note that her political style, while effective, can also be polarising. “She thrives in confrontation," said a Kolkata-based political observer. “But that same approach can make consensus-building difficult."

Yet, her ability to navigate crises remains notable. Time and again, Banerjee has managed to contain political damage and retain her core support base.

The Road Ahead

As West Bengal moves closer to the 2026 assembly elections, Banerjee faces one of the most consequential tests of her political career. Having dominated the state for over a decade, she is now up against not just anti-incumbency but a still-ambitious Bharatiya Janata Party looking to regain momentum after its 2021 defeat.

The challenge this time is two-fold: retaining her strong welfare-backed voter base, while countering criticism over governance, corruption allegations, and organisational fatigue within the TMC.

At the same time, Banerjee continues to position herself as a national opposition figure against Prime Minister Narendra Modi in a balancing act that requires her to stay firmly in control at home while expanding her relevance beyond the state.

“The 2026 election will be a referendum not just on her governance, but on the durability of her political model," political scientist Milan Vaishnav has argued. “If she wins convincingly again, it strengthens her claim as a national player. If not, it could limit her role to a regional power centre."
