Now the political landscape of West Bengal’s capital is facing a seismic shift. New data reveals that the Calcutta Assembly voter deletions 2026 have completely overshadowed the win margins from the 2024 general election. First, every single one of the 11 Assembly segments in the city has seen mass removals. Therefore, seats that were once considered “safe” for the Trinamool Congress (TMC) or the BJP are now wide open. The Special Intensive Revision (SIR) has disproportionately affected the TMC’s core base. Meanwhile, the BJP also faces significant risks in its own traditional pockets.

The SIR Axe: Why 11 Seats Are Now Vulnerable
Now we must analyze the sheer scale of these electoral changes. First, poll panel sources confirm that voter deletions have outpaced winning margins in every city segment. Therefore, the old math of 2024 is now completely irrelevant.
Next, the Trinamool Congress led in 9 of these 11 seats during the last general election. Thus, they have the most to lose from this sudden vacuum.
Meanwhile, the Special Intensive Revision (SIR) focused on verifying residences and identity. Therefore, large groups of the poor and migrant workers were removed. So the Calcutta Assembly voter deletions 2026 have turned the city into a political wild card.
Bhabanipur: Mamata’s Stronghold Faces a 48,000 Gap
So how does this affect the Chief Minister herself? Bhabanipur is the seat held by Mamata Banerjee. First, the TMC led here by only 8,297 votes in 2024. Therefore, it was already a competitive constituency.
Next, the SIR process has removed exactly 48,680 voters from this segment. Thus, the deletion is nearly six times the size of the previous lead.
Meanwhile, BJP heavyweight Suvendu Adhikari is confirmed to be in the fray this time. Therefore, the removal of such a large number of voters creates a massive opportunity for the saffron party. So Bhabanipur is no longer a guaranteed win for the ruling party.
The Muslim Vote: TMC’s Primary Vulnerability
Now the demographic data behind these deletions is starting to emerge. First, sources suggest that Muslims, women, and the poor account for the bulk of the removals. Therefore, the TMC’s most loyal vote bank has been severely depleted.
Next, in Kolkata Port, the TMC led by 42,893 votes in 2024. But the seat has seen 77,125 voters deleted. Thus, the lead has been effectively “erased” by the new list.
Meanwhile, more than 70 per cent of those deleted in Kolkata Port are reportedly from the minority community. Therefore, the party’s foundation in the dock area is crumbling. So the Calcutta Assembly voter deletions 2026 could lead to a total upset in minority-dominated zones.

BJP’s Worry: Deletions in Hindi-Speaking Belts
So is this only a problem for the TMC? Not quite. First, the BJP led in Shyampukur and Jorasanko in 2024. Therefore, they were hoping to build on those leads.
Next, Shyampukur saw 44,693 deletions, while Jorasanko witnessed a staggering 76,524 removals. Thus, the BJP’s slim leads of 1,599 and 7,401 are now mathematically insignificant.
Meanwhile, these two seats are home to many Hindi-speaking Hindu voters. Therefore, the BJP’s own traditional support base has felt the brunt of the SIR axe. So the saffron party should not feel comfortable about these city “wins” yet.
A Seat-by-Seat Breakdown of Mass Deletions
Now let’s look at the raw numbers across the city. First, one particular seat, Chowringhee, saw over 80,000 deletions. Therefore, it is the most volatile segment in Calcutta right now.
Voter Deletion Stats:
Chowringhee: 80,000+ deletions (Lead: 14,645)
Kolkata Port: 77,125 deletions (Lead: 42,893)
Jorasanko: 76,524 deletions (Lead: 7,401)
Beleghata: 66,019 deletions (Lead: 46,112)
So in each case, the “voter gap” is larger than the previous margin of victory. Thus, every single incumbent MLA is facing a completely new electorate. So the 2026 results will depend entirely on which party can re-register their supporters fast enough.
Maniktala: The ‘Smallest’ Deletion is Still 42,000
So which seat saw the least impact? Maniktala witnessed the “smallest” deletion in the city. First, that number was 42,603 voters. Therefore, even the “safe” end of the spectrum is incredibly dangerous.
Next, the TMC led in Maniktala by only 3,575 votes in 2024. Thus, the deletions are more than ten times the size of the victory margin.
Meanwhile, other seats like Rashbehari and Kashipur-Belgachia also have leads under 10,000. Therefore, they are in the “red zone” for potential flips. So the Calcutta Assembly voter deletions 2026 have made the capital a nightmare for poll strategists.

Chowringhee and Kolkata Port: Massive Voter Gaps
Now we must focus on the high-deletion zones. First, Chowringhee’s lead of 14,645 is now dwarfed by 80,000 removals. Therefore, the seat is effectively starting from zero.
Next, Beleghata is also under threat. First, the TMC had a massive lead of 46,112 there. But with 66,019 deletions, that cushion has vanished. Thus, minority voters who previously supported the ruling party are now off the rolls.
Meanwhile, the BJP is eyeing these gaps as a way to enter the heart of the city. Therefore, we can expect a massive voter registration drive from both sides in the coming weeks.
Political Analysts: Can Either Party Recover?
So what do the experts say about this crisis? First, observers suggest that these deletions “cut both ways.” Therefore, neither the TMC nor the BJP can claim an advantage yet.
Next, the party that succeeds in getting its “deleted” voters back on the list will win. Thus, the ground-level workers have a huge task ahead.
Meanwhile, the TMC is already alleging a conspiracy to disenfranchise their voters. Therefore, they are preparing for a legal and street battle over the SIR process. So the Calcutta Assembly voter deletions 2026 are just the beginning of a long political winter.
