Voting in West Bengal's state elections began April 23, with a second phase scheduled for April 29, following a revision carried out by India's Election Commission that removed about 12% of registered voters to eliminate alleged fake entries and undocumented migrants, AP reported on April 23. Voting also took place in Tamil Nadu, while Assam, Kerala and Puducherry held elections on April 9, with results for all five states and the union territory set to be announced on May 4.

The Election Commission conducted a similar revision exercise ahead of the 2025 elections in Bihar, in which the BJP won. The voter roll revision has become a major political flashpoint in West Bengal, with opposition parties alleging it risks disenfranchising poor and minority voters, particularly Muslims, and accusing the government of using the process to shape the electorate ahead of elections. The Election Commission has denied wrongdoing, saying the exercise was a routine clean-up of duplicate, deceased and invalid entries, while the BJP has defended it as standard procedure consistent with national practice.
