Bengal breathes politics. Take a walk through the streets of Howrah, Kolkata or any town in the state and you will find tea stalls where kakus (uncles) argue over ideology, leaders and the future, as if each conversation carries the weight of history. This is not new. From the era of Jyoti Basu, whose long tenure came to define stability and cadre-driven governance, to the upheaval led by Mamata Banerjee in 2011, Bengal has repeatedly shown that when it turns, it turns decisively. Politics here is not distant or abstract. It is woven into everyday life, shaped as much in neighbourhood debates as in party offices.The 2026 assembly election unfolds within that deeply political culture, but with a new layer of uncertainty. Over two phases on April 23 and 29, more than 6.8 crore voters participated to elect their representatives to the 294 member state assembly. Yet this election is not only about turnout or party strength. The Special Intensive Revision of electoral rolls, which significantly reduced the electorate, has made the very act of voting a point of contention.At the centre of the contest lies a sharper bipolarity than before. The Trinamool Congress faces its most direct challenge yet from the Bharatiya Janata Party, turning the election into a contest not just of numbers, but of organisation, cadre strength, identity politics and welfare delivery. Counting day on May 4 will deliver a result (most likely). Whether it signals continuity or another decisive shift is the question that lingers.Here are 10 things you need to know about the Bengal assembly polls 2026:
A historic turnout
The defining statistic of the 2026 election is turnout. Phase 1, covering 152 constituencies, recorded close to 93 per cent participation. Phase 2, across 142 constituencies, approached 90 per cent by late evening, already surpassing previous benchmarks.

At first glance, these numbers suggest an unprecedented surge in voter enthusiasm. The reality is more complex. The Special Intensive Revision reduced the total electorate from around 7.66 crore to approximately 6.82 crore. A smaller voter base inevitably inflates turnout percentages.

Yet this is not only a statistical effect. In Phase 1 constituencies, the absolute number of votes cast rose by roughly 2 lakh compared to 2021. In districts such as Murshidabad, some booths reported turnout exceeding 96 per cent.
SIR-ious Controversy
No issue shaped the 2026 election more than the Special Intensive Revision of electoral rolls. Approximately 90 lakh names, close to 12 per cent of the electorate, were removed prior to polling. Of these, over 60 lakh were categorised as absentee or deceased, while around 27 lakh cases remained under adjudication.The Election Commission has maintained that the exercise was necessary to remove duplicate, deceased and “absent” voters. But the flashpoint has been the category of “logical discrepancy”, under which lakhs were flagged over issues as minor as spelling errors or mismatched records. For many, the line between correction and exclusion has appeared blurred.

Chief minister Mamata Banerjee has been unequivocal, calling the process “arbitrary” and accusing the BJP of attempting to disenfranchise sections of voters. The BJP, in turn, has defended SIR as a long overdue clean-up, arguing that credible elections require accurate rolls.On the ground, the consequences were immediate. In districts such as Murshidabad and Malda, reports of missing names have fuelled anger and anxiety, even as many voters returned home specifically to ensure their presence on the rolls.
What the exit polls predict
Exit polls in West Bengal have long struggled with accuracy. In 2021, several agencies predicted a close contest, with some projecting a BJP advantage. The final result was a decisive Trinamool victory, 215 seats to 77.For 2026, projections remain divided. Some polls suggest the BJP could cross the majority mark, while others indicate a narrow Trinamool edge or even a hung assembly. The spread itself reflects uncertainty. Bengal’s hyper-local political networks, allegations of intimidation, and the complexity introduced by issues such as the SIR make standardised sampling difficult — and it is always with the exit polls, the can (and have very often) can turned out to be wrong on the result day.
Strongholds and swing zones
Bengal’s electoral map remains regionally distinct. North Bengal, including Jalpaiguri and Cooch Behar, has leaned towards the BJP since 2019. In the 2021 assembly election, the party won a majority of seats in this belt, establishing its strongest foothold in the state.South Bengal, particularly the Presidency division covering Kolkata and surrounding districts, remains the Trinamool Congress’s core base. In 2021, the party dominated this region, and Phase 2 of the 2026 election covered many of these constituencies. For TMC, retaining South Bengal is essential to holding power. For the BJP, gains here are necessary to convert its northern strength into a statewide majority. The Matua-dominated areas of North 24 Parganas have emerged as a key battleground, with citizenship promises forming a central campaign plank.
Battle of Bhowanipore
Few seats carry the symbolic importance of Bhabanipur. It is Mamata Banerjee’s constituency and a focal point of political narrative. After losing Nandigram in 2021, she returned to the assembly through a by-election here.

In 2026, the BJP fielded Suvendu Adhikari against her once again, turning the contest into a high-profile rematch. Both sides framed the battle as emblematic of the larger election.Also read: Like Nandigram last time, has BJP set another trap for Mamata in Bhowanipore?Allegations over voter deletions added to the intensity. The Trinamool claimed disproportionate impact on minority voters, while the BJP rejected the charge. Beyond numbers, the outcome in Bhabanipur carries symbolic weight. A Banerjee victory would reinforce her personal authority.A second defeat to BJP’s Suvendu Adhikari, once her close aide, would be a major blow to her prestige, with far-reaching consequences at both the state and national levels.
The candidates
Data from the Association for Democratic Reforms highlights a continuing pattern in Indian elections. Around 23 per cent of candidates in 2026 declared criminal cases, with roughly one in five facing serious charges.

Dozens reported cases related to violent offences, including murder, while others faced allegations involving crimes against women. The distribution cuts across parties.
Women voters
West Bengal’s electorate is close to gender parity, with roughly 3.44 crore women voters. Turnout among women has historically matched or even exceeded that of men, making them a decisive constituency. The Trinamool Congress has invested heavily in welfare schemes targeting women, particularly direct cash transfers such as Lakshmir Bhandar. These programmes played a key role in the 2021 victory and remain central to its campaign.
Welfare politics
Since 2011, the Trinamool government has built an extensive welfare framework. Schemes covering income support, healthcare, and education have created a direct link between the state and households.

This model has reshaped electoral competition. The party’s campaign rests not only on identity or ideology, but on tangible benefits delivered at scale.The BJP has attempted to counter this by promising higher payouts and faster implementation of citizenship provisions. At the same time, it has focused on issues such as corruption, governance, and law and order.The contest is therefore not between welfare and its absence, but between competing claims over delivery, credibility, and intent.
The Left and Congress: From dominance to decline
The scale of the Left Front’s decline remains striking. From uninterrupted rule between 1977 and 2011, it has moved to complete absence in the 2021 assembly.

Its earlier success was built on land reforms and a strong cadre network. Over time, that structure became rigid, and controversies such as Singur and Nandigram eroded its support.Also read: From red to green to saffron? BJP eyes power shift in Bengal as Mamata defends her turfThe Congress, once dominant in the decades after Independence, has followed a similar trajectory. In 2026, it remains present in terms of candidates but lacks a realistic path to power.A significant portion of the Left’s former vote base has shifted to the BJP, reshaping Bengal’s political alignment and turning the contest into a largely bipolar one.
Shift or cycle?
The central question of the 2026 election is whether West Bengal is undergoing a structural political shift or experiencing a cyclical phase of anti-incumbency.The state’s history suggests that when change occurs, it tends to be decisive. The transitions from Congress to Left, and from Left to Trinamool, were not gradual adjustments but sweeping realignments.

The BJP argues that 2026 represents a similar moment. The counterargument is rooted in identity and political culture. Mamata Banerjee’s positioning as a defender of Bengali identity and voting rights continues to resonate with many voters.At the same time, the BJP’s expansion over the past decade is undeniable. From marginal presence to principal challenger, its rise has altered the competitive landscape.What is clear is that Bengal has repeatedly replaced dominant political formations when conditions align. Whether the Trinamool becomes the fourth such case, or retains its position, will be decided by the results.
What to expect
In the end, West Bengal’s 2026 election will be reduced to a single number, the final seat tally on May 4. Yet the days after Phase 2 have already shown that in Bengal, the story rarely pauses when voting ends. As Mamata said during the 2021 assembly polls when her party swept the BJP, ‘khela hobe’. And the ‘khela’ continues on the streets of Bengal even after the second phase polling closed. Mamata herself visited a strongroom in Kolkata, with the TMC alleging irregularities in the handling of ballot units, claims firmly rejected by the BJP and the Election Commission.The images that followed, party workers camping outside counting centres, tightened security, sporadic clashes, have reinforced a familiar truth. In Bengal, elections unfold beyond polling day, in narratives, in suspicion, and in the charged hours before counting.And yet, beneath the noise, one constant stands out. Participation. In an election shaped by uncertainty over voter rolls and intense political messaging, crorse still chose to vote. This will ultimately be the only thing that matters. Whether it delivers continuity or another decisive shift will soon be clear.
