West Bengal Assembly Election 2026: Can Modi’s BJP crack Mamata Banerjee’s TMC stronghold in make-or-break Phase 2?

After record-breaking turnout in Phase 1, the battle reaches its climax on Wednesday as West Bengal heads into the decisive final round, setting the stage for a high-voltage showdown. It’s a crucial test for PM Modi and the BJP as they attempt to breach the formidable stronghold of the TMC and Chief Minister Mamata Banerjee. The Left parties are seeking to regain space in the state they ruled for decades with the Congress also seeking to revive itself in the state that has a significant role in the national polity.

Voting for the second phase will take place with over 3.22 crore eligible voters set to cast their ballots across 142 Assembly seats. While BJP and PM Modi have claimed the first phase’s turnout signals a “BJP wave”, the TMC’s top leaders too have interpreted the record turnout as a wave in its favour.

If the first phase on April 23 tested whether the BJP could retain its traditional edge in north Bengal and adjoining districts, the final round shifts the battle decisively to the TMC’s home turf – Kolkata, Howrah, North and South 24 Parganas, Nadia, Hooghly and Purba Bardhaman.

Who are key faces?

The Phase 2 polling will determine the fate of 1,448 candidates, including 1,228 men and 220 women.

Among key faces in the Phase 2 contest, CM Banerjee is contesting from the Bhabanipur constituency against BJP leader Suvendu Adhikari, who is also in the fray from Nandigram. Banerjee won with a record margin of 58,832 votes in a bypoll in 2021 after losing to Adhikari in Nandigram. However, the recent SIR exercise in the state saw 47,111 voters getting deleted from the constituency in the final electoral roll published on February 28, while another 14,154 voters are currently under judicial adjudication.
Other prominent candidates in this phase include Kolkata Mayor Firhad Hakim, along with ministers Chandrima Bhattacharya, Shashi Panja, Aroop Biswas and Bratya Basu.The BJP has fielded Ratna Debnath, the mother of the victim of the Kolkata’s RG Kar Hospital rape tragedy, from the Panihati constituency. Senior BJP leader Swapan Dasgupta is contesting from Rashbehari, while actor-turned-politician Rupa Ganguly is in the fray from Sonarpur Dakshin.

Why is Phase 2 crucial for Didi?

The constituency is far more than just another seat, it is Mamata Banerjee’s political home turf, the core of her urban stronghold, and a symbol of her dominance in Kolkata. Since 2011, Bhabanipur has consistently backed her, becoming closely tied to her political identity. Spread across eight Kolkata Municipal Corporation wards, Bhabanipur is often called “mini India” – Bengalis, Gujaratis, Marwaris, Jains, Sikhs, Muslims, and migrants from Bihar and Jharkhand packed into the prestigious seat.

This time, however, the battle carries added intensity.

Banerjee has focused unusual personal attention here — padayatras, closed-door meetings in high-rises, outreach to Jain temples and Sikh gurdwaras, and direct canvassing among non-Bengali voters.

Adhikari, after polling in Nandigram, shifted his full focus to Bhabanipur with Amit Shah closely monitoring the campaign from Kolkata. Adding to the pressure, around 51,000 names, nearly 25 per cent of the electorate, were deleted after the SIR.

The contest also comes with historical weight. Bhabanipur was once represented by former chief minister Siddharth Shankar Ray between 1972 and 1977, when the Congress was last in power in the state. A win for Mamata would reaffirm her grip over Kolkata, while a strong showing by the BJP could signal that even the TMC’s most secure bastions are open to challenge.

For the TMC, retaining Bhabanipur is about protecting Banerjee’s authority in her backyard. For the BJP, breaching it would puncture the aura of invincibility around Bengal’s most powerful leader.

What have parties promised?

The battle for Bengal has turned into a fierce contest over the same decisive voter blocs, with both the TMC and BJP pitching aggressively to women, youth and welfare beneficiaries. TMC is banking on the social coalition of women, minorities and SC-ST voters that has anchored the party’s dominance since 2011. The BJP, however, is attempting to disrupt that base with a mix of financial promises, Bengali pride messaging, and a hardline stance on issues such as the Uniform Civil Code, infiltration and citizenship for Hindu refugees.

Recognising women as the TMC’s strongest support base, the BJP has moved to directly challenge it rather than sidestep it. The BJP has promised Rs 3,000 monthly assistance, free bus travel, 33 per cent reservation in government jobs, and dedicated women safety measures such as police stations and ‘Durga Suraksha Squads’. Alongside these assurances, the BJP is seeking to tap into concerns over safety, invoking incidents like RG Kar and Sandeshkhali to build a narrative around security, dignity and fear-free living.

The TMC, in contrast, is reinforcing its traditional support among minorities, who make up nearly 30 per cent of the electorate and influence a large number of seats. Its manifesto includes assurances on Waqf properties, educational institutions like Aliah University, and skill development in minority-dominated areas—moves aimed at consolidating a constituency wary of the BJP’s assertive campaign and rising communal rhetoric.

Additionally, BJP promises to implement the Uniform Civil Code, curb infiltration, and act against ‘Love Jihad’ and ‘Land Jihad’ are designed to consolidate Hindu votes.

Meanwhile, the Left Front and Congress, locked out of the central power contest, are focusing on reclaiming relevance by shifting the narrative away from identity politics to bread-and-butter issues. Their campaigns centre on jobs, industrial revival and welfare delivery without corruption. The Left has promised employment guarantees and industrial expansion, while the Congress has offered a moderated welfare model, arguing that social support can continue without the baggage of anti-incumbency.

How SIR will impact polls

West Bengal’s 2026 election may ultimately hinge not on the headline arithmetic of 294 seats, but on a clutch of 65–70 razor-thin constituencies where margins are wafer-thin and the Special Intensive Revision (SIR) of electoral rolls has dramatically reshaped the contest. From Nandigram to Bhabanipur, and across the Matua-dominated belt of North 24 Parganas to the minority-heavy districts of Murshidabad and Malda, recent electoral data shows how narrow the gap has become—often just 8,000 to 15,000 votes in the 2024 Lok Sabha segments, and even tighter in the 2021 Assembly polls, where several MLAs scraped through with margins as low as a few hundred votes.

Now, with over 90.83 lakh names, nearly 11.85 per cent of the electorate, deleted from the rolls till April 7, the electoral battlefield has shifted sharply. Nearly 27.16 lakh of these deletions fall under the “under adjudication” category, with the epicentre spread across about 70 seats in 11 districts. The highest concentration lies in Kolkata and its adjoining belts—North 24 Parganas, Howrah and Hooghly—followed by districts like Murshidabad, Malda, Bankura, Purulia, the Bardhamans and the Medinipurs. North 24 Parganas alone accounts for 13 such closely contested seats, while Murshidabad has 10 and Bankura-Purulia nine.

The TMC alleges targeted deletions affecting minorities, migrants and poor Bengali-speaking voters. The BJP maintains the exercise was necessary to remove bogus entries and correct years of alleged roll distortions.

The implications are enormous. Analysts told PTI that even a 1 per cent swing in vote share could flip at least 15 of these seats, while a 2 per cent shift could change the outcome in more than 20 constituencies.
