BJP’s West Bengal Sweep Was Broad, But the Numbers Reveal a More Complicated Story |
Listen to this article:
Kolkata: The West Bengal result numbers point to a decisive BJP victory, with the party winning 206 seats and establishing a lead across multiple social and geographic categories. But beneath the scale of the win lies a more complex story. The BJP’s dominance was structurally broad, yet not uniform.
A constituency-wise reading of the result data points to a BJP victory built on SC-ST consolidation, urban gains, district-level sweeps, and a strong performance across migration zones. However, the figures also show that voter-roll deletions may have mattered in a set of close, demographically sensitive seats.
Two terms are central to the analysis. ASDD deletion refers to the removal of names marked as Absentee, Shifted, Dead or Duplicate from the SIR draft voter list. UA Deleted, or “Under Adjudication – Not Eligible,” refers to over 27 lakh voters whose citizenship or residency status was flagged during the West Bengal SIR 2026 voter-roll verification process and who were temporarily excluded from voting until their documents were cleared by the judicial tribunal.
Here are ten key takeaways from the initial numbers.
BJP’s 206-seat victory was decisive, but SIR may have mattered in close seats

The BJP’s reported tally of 206 seats reflects a commanding performance. Its average winning margin stood at around 27,939 votes, while the average margin after accounting for UA deletions was around 20,931 votes.
The most politically sensitive figure, however, is the “Margin-UA Deleted” metric. In 25 BJP-won constituencies, the number of voters found “not eligible Under Adjudication” was greater than the BJP candidate’s winning margin.
While this does not establish that all such voters would have voted against the BJP, it does show that the scale of voter-roll deletion was larger than the victory margin in these areas, making the outcome highly sensitive to the Special Intensive Revision (SIR) process. It is well established that the sharpest political concern around UA deletions is their concentration in Muslim-heavy constituencies.
Several BJP victories where the number of UA deletions exceeded the winning margin came from constituencies with large Muslim populations, particularly in Murshidabad, Uttar Dinajpur, Malda, Nadia, Purba Bardhaman and South 24 Parganas. In political terms, this makes the SIR process especially questionable because the most affected constituencies were often minority-heavy and closely contested.

Several seats illustrate this pattern. In Jangipur, the BJP’s margin was 10,542, while 36,581 UA voters were deleted. In Karandighi, the margin was 19,869 against 31,562 UA deletions. In Bhatar, the BJP won by 6,528 votes, while 17,481 UA voters were deleted.
The broader conclusion is that the BJP won decisively overall, but the final scale of its victory may have been affected by voter-roll revision in a cluster of close seats.
Minority-heavy seats remained more competitive, even as BJP broke through in 18 of them

In constituencies where the minority population exceeded 30%, Trinamool Congress (TMC) remained comparatively stronger than in much of the rest of the state, winning 56 seats. The BJP, however, still managed to win 18 such constituencies, a politically significant breakthrough in seats where minority voters form a major part of the electorate.
The BJP’s wins in these constituencies were concentrated in districts such as Murshidabad, Nadia, Purba Bardhaman, Uttar Dinajpur, Malda and South 24 Parganas. In Murshidabad, the BJP won seats including Jangipur, Murshidabad, Nabagram, Khargram, Burwan, Kandi and Beldanga. In Nadia, it won Karimpur, Tehatta and Nakashipara. In Purba Bardhaman, it won Monteswar, Ketugram and Mangalkot. It also won Karandighi and Hemtabad in Uttar Dinajpur, Manikchak and Baisnabnagar in Malda, and Satgachhia in South 24 Parganas.
Notably, several of these BJP victories had negative Margin-UA Deleted values, including Jangipur, Nabagram, Nakashipara, Monteswar, Mangalkot, Karandighi, Hemtabad, Manikchak and Satgachhia. This indicates that in a number of minority-heavy seats, the number of UA voters deleted was larger than the BJP’s winning margin. While the dataset does not identify the religion of each deleted voter, the constituency-level pattern suggests that Muslim/minority-concentrated seats were among the most affected by UA deletion.
But SIR alone cannot explain the shift in minority-heavy constituencies. There are at least 32 seats where Muslims make up more than 50% of the electorate. In these 32 seats, the total votes cast reportedly increased by 7.6% in 2026 compared to 2021. Yet TMC’s vote share fell by more than 16 percentage points. TMC had won all 32 seats in 2021. This time, it won 23.
That indicates a real political swing, not merely a turnout suppression story. The biggest chunk of the lost TMC vote appears to have moved toward the Left/Indian Secular Front........
