In a first in the country, campaigning for nine Lok Sabha seats in West Bengal going to polls in the last phase came to an end at 10 pm on Thursday, 20 hours before the scheduled time, as per orders of the Election Commission.

Polling will be held in nine constituencies of south Bengal on Sunday where an electorate of 1,49,63,064 will decide the fate of 111 candidates, the EC said.

Seats in which elections will be held on Sunday are Kolkata North and Kolkata South, Dum Dum, Barasat, Basirhat, Jadavpur, Diamond Harbour, Jaynagar (SC) and Mathurapur (SC) seats.

In a first such action in India's electoral history, the Election Commission had Wednesday ordered campaigning in the nine West Bengal constituencies to end at 10 pm on Thursday, instead of 6 pm on Friday, in the wake of violence between the BJP and the TMC in the city during Amit Shah's roadshow.

A total 710 companies of central forces are being deployed by the EC to cover almost all polling booths of the nine seats to ensure free and fair voting on Sunday, officials in the poll panel said.

The nine seats are spread across the three districts of Kolkata, South and North 24 Parganas. Eight seats, barring the Jadavpur seat, will see a four-cornered contest between the Trinamool Congress, the BJP, the Congress and the Left Front.

Jadavpur will witness a triangular fight as the Congress has not put up its candidate in the seat.

The high-voltage campaign saw poll meetings by Prime Minister Narendra Modi, BJP president Amit Shah, Uttar Pradesh Chief Minister Yogi Adityanath, Congress leader Sachin Pilot and West Bengal Chief Minister and Trinamool Congres supremo Mamata Banerjee.

The prime minister held two poll meetings on the last day at Mathurapur in South 24 Parganas and Dum Dum in North 24 Parganas, while Banerjee held two road shows at Behala and Jadavpur areas of the city and two poll meetings at Mathurapur and Diamond Harbour.

Shah's roadshow in the city on Tuesday saw violence and destruction of social reformer Ishwar Chandra Vidyasagar's bust in a college in north Kolkata named after him.
