Polling began at 7 am on Thursday for the by-election to the Bhabanipur seat, where West Bengal Chief Minister Mamata Banerjee is contesting, and two other constituencies amid tight security and stringent COVID-19 measures, officials said.
Ms Banerjee, who lost from the Nandigram constituency in the assembly elections earlier this year, has to win this by-poll to retain the chief minister’s post.
A total 6,97,164 voters are eligible to exercise their franchise in the three constituencies. Votes will be counted on October 3.
The by-polls are being held in south Kolkata’s Bhabanipur, besides Jangipur and Samserganj seats in Murshidabad district.
