A record deletion of voters turned out to be one of the major aspects of this year's assembly elections in West Bengal - one that saw the BJP thundering into the Trinamool fortress, ending a 15-year regime helmed by Chief Minister Mamata Banerjee.
Just before the elections, over 90 lakh
electors in the state found their names deleted from the voters' lists months
after the Election Commission took up a Special Intensive Revision (SIR) of the
voter rolls, aimed at cleaning its records of dead and duplicate voters.
Trinamool alleged the SIR process was
targeted and alleged bias, fearing that it could lose out on its voter base.
With the party now losing power, it warrants a look into how the deletions
tallied with the vote counts for the Trinamool and the BJP.
SIR Deletions vs Vote Counts
Over 25,000 names had been deleted in 147
constituencies of Bengal. A review by NDTV shows that a massive chunk of these
went to the BJP. The party won 95 out of these 147 seats, while the Trinamool
bagged nearly half, 51. Congress won just one.
In 67 seats where the deletions were between
15,000 and 25,000, the BJP again emerged as a winner. Out of these, the BJP won
47 seats, while the Trinamool won 19 seats and Congress one.
Out of 62 seats where the deletions were between 5,000-15,000, the BJP won 50, and the rest were clinched by the Trinamool. All 13 seats where the deletions were below 5,000 were won by the BJP.
During the adjudication process, the maximum
number of cases deemed "excludable" were from the Murshidabad
district. Here, over 4.55 lakh cases were deleted, followed by North 24
Parganas (3,25,666), and Malda (2,39,375).
In Murshidabad, Trinamool had won 20 out of
22 seats in 2021; it dropped to just nine this time, indicating a split in the
minority votes and a consolidation of Hindu votes in favour of the BJP.
A similar trend followed in North 24
Paraganas. Out of the 33 seats in this district, the Trinamool had won 28 seats
in 2021, dropping to just eight this time. In Malda's 12 seats, the party's
share went down from eight seats in 2021 to six this time. The remaining were
won by the BJP.
The SIR Process
Conducted by the Election Commission, the SIR
exercise was a contentious issue in West Bengal, a state that shares more than
2,200-km border with Bangladesh.
The exercise found a record 91 lakh voters
deemed ineligible to vote in the country's elections.
The total number of voters stood at over 7.66
crore here before the notification for the SIR process was issued last
November. A draft voters' list published in December showed that over 58.20
lakh names were deleted. The deletions increased to 63.66 lakh after the final
list was published on 28 February.
As per the figures provided by the Chief
Electoral Officer's office, over 60.06 lakh cases were referred for
"judicial adjudication" in February. Of these, 27,16,393 voters were
deemed "excludable", taking the total number of deleted voters to
90,83,345.
