The Muslim vote in West Bengal gives a party a head start - not a veto.
In the 2021 West Bengal Legislative Assembly election 2021, the seven seats decided by fewer than 1,000 votes were Balarampur (margin 423), Dantan (623), Tamluk (793), Jalpaiguri (941), Ghatal (966), Kulti (679), and Dinhata (57).
Six of these have majority-community populations above 85 per cent. The seventh, Dinhata, has a minority-community population of 31 per cent, yet the BJP won it. Dinhata's minority-community share of 31 per cent is approximately the same as the projected minority-community share of West Bengal's population in the upcoming Census.
That is why the author thought it prudent to treat Dinhata as an appropriate case to test the claim of a 'minority veto' in West Bengal, even though the seat later went to the All India Trinamool Congress(TMC) in a bypoll. TMC's bypoll victory is credited to fear of state mobilisation, post-poll violence and larger trend of bypolls being pro-incumbency.
Of the 22 BJP victories with margins under 5,000, as identified by the Trivedi Centre for Political Data after the 2021 election, not one is a Muslim-supermajority (with share in population above 40 per cent) constituency. Of the 13 TMC seats in the same narrow-margin band, not one is either.
Not one seat decided by fewer than 1,000 votes had a Muslim-supermajority.The seats where the 2021 election was genuinely contested share a common feature: the minority community vote played no structural role in determining the outcome.
The reasons for this range from wastage of excess votes to overestimation of the minority community's electorate in elections.
The Arithmetic of Margins
Muslims constitute 27.01 per cent of West Bengal's population according to Census 2011, the third-highest state-level share in India after Jammu and Kashmir and Assam. The standard political claim is that Muslims are the decisive demographic in 80 to 90 seats or even 100-plus seats out of 294 in the West Bengal Assembly.
As a result, most analyses of Bengal 2026 typically begin with Murshidabad alignments, ISF's 37-seat allocation in 2021, OBC certification disputes, and voter roll revisions in border districts.
This piece examines those assumptions against constituency-level data across three election cycles.
According to Census 2011, although the Muslim community constitutes 27.01 per cent of West Bengal's population, it has a majority in only three - 13.04 per cent of total - districts namely Murshidabad (66.27 per cent), Malda (51.27 per cent), and Uttar Dinajpur (49.92 per cent).
Muslim-majority districts are three. The 80-seat claim counts twenty-three.Beyond this northern belt, Birbhum (37.06 per cent), South 24 Parganas (35.57 per cent), Nadia (26.76 per cent), North 24 Parganas (25.82 per cent), Howrah (24.44 per cent), and Kolkata (20.27 per cent) are other districts with a significant Muslim population.
In the western districts of Purulia (7.76 per cent), Bankura (8.08 per cent), Paschim Medinipur (12.27 per cent), and Jhargram, the Muslim population is too dispersed to shape electoral outcomes.
The claim that the minority community vote determines outcomes in 80-120 of West Bengal's Assembly seats is largely derived by counting every assembly seat within a district where the district-wide Muslim share of the population exceeds 25 per cent.
The underlying assumption here being that the voters of Muslim community vote en bloc, which means any party having their support begins with a 24-25 per cent base.
For an electoral win in such seats, that particular party party needs to secure just 10 to 15 per cent of Hindu votes while expecting the rest of the Hindu vote to split between the contestants.
This rarely materialises in reality, and in the 2026 assembly elections, the probability of a multipartite contest or a hung assembly is at its lowest in three decades.
Additionally, this method does not examine whether individual seats within that district have the Muslim concentration required to matter under the first-past-the-post (FPTP) system.
Under FPTP, a community's ability to be decisive requires that its members constitute a large enough share of the constituency electorate and vote with sufficient cohesion to determine the outcome.
(Although, on that count, the analyses of the minority community voting patterns tallies with the assumptions. Post-poll survey data from 2021 election shows Muslim voter consolidation behind a single party at 70 to 75 per cent. Hindu consolidation is more fragmented, with the BJP's Hindu vote share peaking at 57 per cent in 2019 and falling to 50 per cent in 2021).
Counting by District, Losing by Constituency
Given these differentials, as well as the increasingly polarised nature of West Bengal elections, the threshold at which minority community concentration becomes genuinely decisive under FPTP is approximately 38 to 40 per cent of the constituency population.
Set against this 38-40 per cent threshold, much of the expansive seat arithmetic attributed to minority community influence begins to look overstated
For instance, North 24 Parganas has a Muslim population of 25.82 per cent and 33 assembly seats, the highest for any district. The 80 to 90 figure supposedly counts most of these.
But Muslim-concentrated seats cluster in a narrow Bangladesh border belt of Baduria (TMC won in 2021 by 56,444 over BJP), Deganga (TMC by 32,537), Haroa (TMC by 80,978), Basirhat Uttar (TMC by 89,351), Basirhat Dakshin (TMC by 24,468 over BJP), Amdanga (TMC by 25,480), and possibly Habra (TMC by 3,841).
That is five to seven seats out of 33.
The remaining 26 seats in North 24 Parganas tell a different story.
The Matua-dominant constituencies such as Bangaon Uttar (BJP by 10,488), Bangaon Dakshin (BJP by 2,004), Gaighata (BJP by 9,578), and Bagda (BJP by 9,792) went to the BJP.
In the industrial belt of Kamarhati (TMC by 35,408), Bhatpara (BJP by 13,687), and Jagatdal (TMC by 18,364), and in urban seats such as Bidhannagar (TMC by 7,997), Rajarhat New Town (TMC by 56,432), Barasat (TMC by 23,783), Baranagar (TMC by 35,147), and Dum Dum (TMC by 26,731), TMC dominated.
In each of these 26 seats, the outcome was almost certainly determined by Hindu voter behaviour, including Matua community dynamics and local incumbency.
Malda, with a 51.27 per cent Muslim population and 12 seats, offers the inverse. The district is Muslim-majority, yet four of its twelve seats, namely Gazole (SC-reserved, tribal-heavy, BJP by 1,798), Habibpur (ST-reserved, BJP by 19,517), Maldaha (SC-reserved, BJP by 15,456), and English Bazar (urban headquarters, BJP by 20,099), were won by the BJP. All four have seat-level demographics that are not Muslim-majority despite being located within a Muslim-majority district.
The remaining eight seats, namely Sujapur (TMC by 130,163 with 73.44 per cent vote share), Harischandrapur (TMC by 77,473), Chanchal (TMC by 67,338), Ratua (TMC by 75,650), Malatipur (TMC by 91,949), Mothabari (TMC by 56,573), Manikchak (TMC by 33,878), and Baishnabnagar (TMC by 2,471), followed a different pattern.
The last of these, with an approximately equal Hindu-Muslim split, was the sole genuinely competitive seat in the district.
Applying consistently across the remaining districts, the same pattern holds: a high aggregate Muslim population does not translate into uniform electoral dominance.
In South 24 Parganas (35.57 per cent; 31 seats), Muslim influence is geographically concentrated. Roughly four to six constituencies in the Bhangar-Canning belt are Muslim-decisive, while the bulk of the district's seats lie in SC-reserved Sundarbans segments, Hindu-majority suburban stretches, or the Kolkata-adjacent urban periphery.
In Uttar Dinajpur (49.92 per cent; 9 seats), the near-even demographic split produces a clearer bipolarity: around five border constituencies adjoining Bangladesh are Muslim-decisive, while the remaining four have substantial Hindu and Rajbongshi consolidation.
In Birbhum (37.06 per cent; 11 seats), Muslim concentration is limited to the eastern belt comprising Nalhati, Murarai, and Rampurhat, yielding three to four decisive seats, with the western half of the district remaining predominantly Hindu.
In Nadia (26.76 per cent; 17 seats), Muslim influence is largely confined to two or three border constituencies. The electoral centre of gravity instead lies in the Matua-dominated Ranaghat subdivision and the Hindu-majority Krishnanagar cluster.
Only in Murshidabad (66.27 per cent; 22 seats) does demographic weight translate into near-complete electoral dominance. Around 20 constituencies can be classified as Muslim-decisive and have consistently favoured the All India Trinamool Congress, while the Bharatiya Janata Party has broken through in just two, Baharampur and Murshidabad, both characterised by relatively stronger Hindu voting blocs.
Across seven districts of Murshidabad, Malda, Uttar Dinajpur, Birbhum, South 24 Parganas, North 24 Parganas, and Nadia, the concentration of Muslim voters is high enough for them to be decisive in a sizeable bloc of seats.
The aggregate across these districts is as follows. In Murshidabad, 20 of 22 seats are Muslim-decisive. In Malda, the figure is 8 of 12. In Uttar Dinajpur, 5 of 9. In Birbhum, 3 to 4 of 11. In South 24 Parganas, 4 to 6 of 31. In North 24 Parganas, 5 to 7 of 33. In Nadia, 2 to 3 of 17.
Aggregating these seven districts yields roughly 47 to 54 assembly seats out of 135 where Muslim voters are plausibly decisive, depending on how strictly one defines decisive.
District-by-district, the 80-seat claim collapses to roughly 47-54.The remaining 159 seats are spread across Hooghly, Howrah, Kolkata, Paschim Medinipur, Purba Medinipur, Bankura, Purulia, Jhargram, Darjeeling, Jalpaiguri, Alipurduar, Cooch Behar, Dakshin Dinajpur, and the Bardhaman districts. There, district-level Muslim populations are generally below 25 per cent and are not concentrated enough to be decisive at scale, though there are significant pockets.
Even outside the core Muslim-majority districts, there are identifiable belts of concentration. In Uluberia, municipal-level data places the Muslim population close to 45 per cent, with parts of the surrounding Howrah belt showing similar patterns, though constituency-level variation is significant.
By contrast, areas such as Arambagh remain closer to 20 per cent, well below the inflated figures sometimes cited.
Within Kolkata, concentrated pockets such as Metiabruz and Garden Reach form clear Muslim-majority clusters, with estimates often placing them above 60 per cent, despite the city-wide share being around 20 per cent.
In Purba Bardhaman, while the district average is about 25 per cent, specific blocks reach into the low- to mid-30s, though such concentrations are localised rather than constituency-wide.
Structurally, these are isolated concentrations rather than contiguous clusters, and most fall short of the threshold needed for a community to be independently decisive in a first-past-the-post system.
A majority in the 294-seat West Bengal assembly requires 148 seats. At the upper bound of 54 to 60 Muslim-decisive seats, that amounts to about 36.5 to 40.5 per cent of the majority threshold, meaning that the Muslim-decisive bloc is substantial but not, by itself, decisive statewide.
Even in a hypothetical scenario where Muslims vote with 100 per cent cohesion and deliver 60 seats to a single party, that party would still need 88 additional seats from the remaining 238, a 37.61 per cent strike rate in non-Muslim-decisive constituencies. (Bear in mind that in such a scenario of total minority-vote polarisation, a counter-polarisation is bound to be triggered).
At maximum consolidation, the Muslim vote still leaves a party 88 seats short - and triggers the counter it cannot afford.The Muslim vote at maximum consolidation is a necessary but not sufficient condition for a two-thirds majority.
It is not a sufficient condition for a simple majority.
It is not a veto.
Decisive on Paper, Wasted in Practice
Within those 50 to 56 seats, a significant share is structurally wasted. The 20 Murshidabad seats are never competitive. In 2021, TMC won Bhagabangola by 106,008, Jalangi by 79,276, Farakka by 59,945, Domkal by 47,229, Kandi by 38,080, and Hariharpara by 14,066, the tightest race in the district.
Every vote above the winning threshold in these seats is a vote that elected no one. In Sujapur alone, TMC wasted over 100,000 surplus votes, enough to swing two or three tight seats elsewhere. In the Muslim-decisive seats, TMC's average victory margin was above 50,000 votes. In its 13 narrowest victories statewide, all in non-Muslim seats, the average margin was under 3,000.
TMC won Sujapur by 1,30,000. Those votes elected one MLA. Spread across tight Hindu-majority seats, they could have decided ten.The uncompetitive seats are all in the same belt.TMC's winning-seat vote share in the Muslim belt was higher, but the spread between winning and overall vote share was minimal, because TMC won almost every seat in that belt.
The party's victories in the Muslim-decisive seats were emphatic and uniform. Its victories elsewhere were distributed across a wider range of margins, with a significant tail of razor-thin wins, the seats where the composition of the assembly was actually determined.
The electoral consequence of this is that the same number of Muslim voters distributed more evenly across the state would carry far greater weight under FPTP than they do when concentrated in supermajority pockets.
Anatomy of a Consolidation
The question of how Muslim votes came to be concentrated behind TMC is answered by the 2016 baseline. In that election, TMC won 211 seats with 44.91 per cent of the voteshare. Congress won 44 with 12.25 per cent. CPI(M) won 26 with 19.75 per cent. BJP won 3 with 10.16 per cent.
Congress's 44 seats were heavily concentrated in Murshidabad and Malda, which together accounted for roughly half its tally, with the remainder scattered across Uttar Dinajpur and a few pockets in central and south Bengal. By 2021, Congress's statewide vote share had fallen to 2.93 per cent, with seat count falling from 44 to zero.
Its decline also impacted the party-wise share of Muslim legislators. In 2016, Bengal's assembly had 59 Muslim MLAs: TMC 32, INC 18, Left parties 8, All India Forward Bloc 1. In 2021, the total fell to 42: TMC 41, RSMP 1 (ISF's Nawsad Siddique at Bhangar). Congress and CPI(M) returned zero.
TMC fielded 56 Muslim candidates in 2016 and 44 in 2021. Muslim representation in the assembly declined from 59 to 42 despite the population share remaining constant at 27 per cent.
Muslim representation fell from 59 MLAs to 42 - not because the community shrank, but because Congress disappeared.The decline was a function of Congress and the Left ceasing to exist as electoral vehicles capable of returning Muslim candidates.
For instance, in Baishnabnagar, Malda, the constituency has an approximately equal Hindu-Muslim split. In 2016, BJP's Swadhin Sarkar won with 38.2 per cent against Congress's 35.75 per cent and TMC's 21.91 per cent, a genuine three-way contest.
In the 2019 Lok Sabha, BJP led the assembly segment with 41.57 per cent, TMC at 28.14 per cent, Congress at 26.68 per cent. In 2021, the three-way contest collapsed. Sarkar increased his vote share to 38.62 per cent but lost by 2,471 votes. TMC's Chandana Sarkar won with 39.81 per cent. Congress collapsed to 17.95 per cent. BJP's Muslim vote was near zero in all three elections.
The 17.8 percentage-point decline in Congress's vote share between 2016 and 2021 flowed almost entirely into TMC. Sarkar on record said, "It's true that we did not get Muslim votes at all. I have never recorded so many single-digit figures like this time."
In neighbouring Sujapur (approximately 89 per cent Muslim), the 2016 winner was Congress's Isha Khan Choudhury with 58.46 per cent vote. TMC polled under 30 per cent. By 2021, TMC won with 73.44 per cent and Congress fell to 10.73 per cent. BJP fell to 7.12 per cent, polling zero votes in 19 of 366 booths and single-digit votes in 244 of them.
The 2024 Lok Sabha, however, showed that this consolidation was not permanent. In Malda Dakshin, the parliamentary constituency containing both Sujapur and Baishnabnagar, Congress won by 128,368 votes. In the Sujapur assembly segment, Congress took a lead of 83,629 votes over TMC, reversing a 130,163-vote TMC lead from 2021.
In Baishnabnagar's segment, BJP led with 41.57 per cent, TMC fell to 28.14 per cent, Congress recovered to 26.68 per cent, nearly identical to the 2019 pattern.
The same Muslim voters who delivered 130,000-vote margins in 2021 swung to Congress in 2024. The consolidation was never permanent.In Raiganj in Uttar Dinajpur, the Muslim vote split between TMC at 36 per cent and the Congress-Left alliance at 19.24 per cent, and BJP won at 41 per cent.
In four Lok Sabha seats across North and South 24 Parganas-Barasat, Basirhat, Jaynagar, and Mathurapur-the Indian Secular Front came third, overtaking the Left-Congress alliance and polling 6.5 lakh votes in aggregate. The consolidated Muslim vote bank was a function of Congress's absence. The moment Congress returned as a credible vehicle, voters returned to it.
Both parties' 2021 performances demonstrate the same finding from opposite ends.
The Bharatiya Janata Party won 77 seats with negligible Muslim support. Its vote share surged from 10.16 per cent in 2016 to 38.13 per cent in 2021, a 28 percentage-point jump driven overwhelmingly by Hindu consolidation.
In the Jalpaiguri division, comprising Darjeeling, Jalpaiguri, Alipurduar, and Cooch Behar, the BJP secured 30 seats to the All India Trinamool Congress's 23. In Bankura, it led 8 to 4, and in Purulia, 6 to 3. Even in Nadia, a more competitive district demographically, the BJP edged ahead 9 to 8.
BJP won 2 seats in Murshidabad (Baharampur and Murshidabad town), 4 in Malda (Gazole, Habibpur, Maldaha, English Bazar), and 4 in Hooghly (Pursurah, Arambag, Goghat, Khanakul). BJP did not win a single seat in Howrah (16 seats), Kolkata (11 seats), or South 24 Parganas (31 seats, excluding Bhangar won by ISF).
TMC's 213 seats tell the same story. Subtract the 47 to 54 Muslim-decisive seats: 159-plus victories came from Hindu-majority or mixed constituencies. Post-poll survey data show TMC's Hindu vote share rose from 32 per cent in 2019 to 39 per cent in 2021. Among women, 50 per cent voted TMC, rising above 55 per cent among women from poor households.
TMC swept Kolkata (11 of 11), where margins ranged from 12,743 at Jorasanko to 75,359 at Ballygunge. It swept Howrah (all 16 seats), where aggregate vote share was 51 per cent against BJP's 36 per cent, while individual margins ranged from 5,522 at Howrah Uttar to 50,569 at Howrah Dakshin.
At Domjur, where TMC defector Rajib Banerjee contested on a BJP ticket, TMC won by 42,620. In Hooghly (18 seats, Muslim population 15.14 per cent, below the threshold in every constituency), TMC won 14 to BJP's 4, with BJP's victories at Arambag (7,172), Goghat (4,147), Pursurah (28,178), and Khanakul (12,884).
In the Jangal Mahal belt, TMC recovered seats lost in the 2019 Lok Sabha: Jhargram by 37,996, Gopiballavpur by 23,604, all tribal and SC-dominated constituencies with negligible Muslim presence.
In structural terms, the 2021 supermajority of TMC was a story of a certain section of Hindus' tilt, welfare-driven and women-anchored schemes, that required Muslim consolidation to hold perhaps 40 seats. The other 173 TMC victories were decided by other variables not directly related to the minority vote consolidation.
Both parties, from opposite ends, prove that arithmetically, the minority community does not hold a veto over Bengal's assembly.
Head start, yes. Veto, no.
The "Muslim veto" narrative survives because every major political player in Bengal benefits from keeping it alive. For the TMC, painting the minority community as dependent on Mamata Banerjee's protection lets her pose as the guardian of 'secularism' - a label that shields her from being held accountable for poor governance even in the 200-plus seats where Muslim voters are not a significant factor. As long as the political conversation is about communal arithmetic in Berhampore, nobody is talking about unemployment in Hooghly or the state's fiscal mess in Kolkata.
For BJP, a threat of 'minority veto' drives majority consolidation. The party's 2021 campaign, from Dilip Ghosh's rhetoric to Suvendu Adhikari's speeches, explicitly treated Bengal as a Hindu-versus-Muslim contest. The party benefits from the perception that it faces a minority community vote bank, because the perception is the mobilisation tool.
For the AIMIM and the Indian Secular Front, a community that "decides Bengal" sustains a market for community-specific parties. Abbas Siddiqui launched ISF on the premise that the Muslim community in the state needed its own political vehicle that vehicle would be electorally decisive.
ISF was allocated 37 seats in the Sanyukta Morcha alliance, but won only Bhangar, in South 24 Parganas, by 26,151 votes. The victory has been attributed to factional discontent within the local TMC unit rather than any organised community mobilisation.
A community decisive in 50-odd seats out of 294 does not sustain a statewide political party. ISF's single-seat result was the market correction.
Four Variables That Will Settle 2026
The numbers that will in fact shape 2026 operate outside the Muslim-decisive belt. The SIR voter roll revision has pruned approximately 91 lakh names from the electoral rolls statewide, reducing total voters from 7.66 crore to 6.75 crore.
The 2026 election will turn on four variables that lie far from Berhampore or Sujapur.
The first is welfare credibility. Lakshmir Bhandar, with its Rs 1,000 monthly transfer to women, underwrote the All India Trinamool Congress sweep in 2021. The question now is durability, and whether the Bharatiya Janata Party can mount a credible counter through its Annapurna Yojana promise.
The second is the voter roll. The Special Intensive Revision has pruned 63.66 lakh names across more than 125 constituencies, with the sharpest impact in the Matua-Namasudra belt of North 24 Parganas and Nadia. This is less about arithmetic than machinery, about which party can register, retain, and mobilise voters under tighter enumeration.
The third is the Indian National Congress returning to relevance in Malda and Murshidabad. A serious contest here fractures the 2021-style consolidation behind TMC, turning 20 to 30 Muslim-heavy seats into three-cornered fights. That makes the Muslim vote consequential at the margin without making it decisive statewide.
The fourth is the ceiling on consolidation. In 2021, the BJP's Hindu vote plateaued around 50 per cent after peaking in 2019. Breaking past that limit in the roughly 160 seats where it is competitive is the difference between a surge and a stalemate.
If the race tightens to something like 155 versus 130, the Muslim-concentrated seats matter, but only at the edges. The centre of gravity lies elsewhere, in Howrah, Hooghly, the Matua belt, and Jangal Mahal.
Landslides are produced by outliers, by six-figure margins and vote shares in the seventies. The standard election though is decided in the narrower terrain, in four-digit margins across Hindu-majority seats, where women weigh welfare against delivery and Matuas weigh documentation against access. That is where 'Bengal 2026' will likely be settled.
