Over three lakh voters of Bhabanipur, a south Kolkata legislative constituency, casted their votes today, to seal the fate of Trinamool Congress leader Mamata Banerjee, who is looking to enter the state Assembly before the end of her six-month period of Chief Ministership-without-being-an-MLA.

The constituency, which has twice elected Mamata and is considered her home, has pitted the Trinamool Congress supremo against two young faces — BJP’s Priyanka Tibrewal and the CPM’s Srijib Biswas.

The Thursday bypoll saw a relatively low voter turnout amidst isolated disturbances. At the same time, byelections to two other seats in the State and to the Pipili Assembly seat in Odisha saw a higher turnout.

Till 5 p.m., about 53.32% voters had exercised their franchise in Bhabanipur, compared to 76.12% in Jangipur and 78.60% at Samserganj, where, along with Pipili, elections were adjourned due to the death of candidates during the Assembly polls in April.

Banerjee, who is contesting the bypoll from Bhabanipur Assembly constituency to retain her chair, cast her vote at Mitra Institution School around 3 pm.

The results of the four elections will be out on October 3. The Bhabanipur bypoll is crucial, as Banerjee had lost the election from Nandigram in May.

BJP candidate from Bhabanipur Priyanka Tibrewal raised allegations of electoral malpractices at some of the polling booths. The office of the Chief Electoral Officer denied the allegations, saying no irregularities took place.

The BJP also raised allegations against Ministers Firhad Hakim and Subrata Mukherjee, claiming that they were moving around polling booths and trying to influence voters. Both denied the allegations, saying they were merely interacting with party supporters at different party offices and did not try to influence voters.

A vehicle of BJP leader Kalyan Chaubey was attacked and damaged at Bhabanipur. According to the police, there was no political connection with the incident and the attack was due to an altercation with a person on a motorbike.
