Kolkata: Seven Lok Sabha constituencies spread across three districts in West Bengal will go to polls in the fifth phase of elections on Monday. The ruling Trinamool Congress, the BJP, the Congress and Left Front constituent CPI(M) are the main contenders in the seven seats where the fate of 83 candidates will be decided by a 1,16,91,889-strong electorate. To ensure free and fair polling in Bongaon (SC), Barrackpur, Howrah, Uluberia, Serampore, Hooghly and Arambagh (SC) seats, the Election Commission will deploy a total of 578 companies of central forces, which will cover almost 100 per cent polling booths, officials said.

The campaign for these constituencies have seen poll meetings by Prime Minister Narendra Modi, BJP chief Amit Shah and West Bengal Chief Minister Mamata Banerjee. Banerjee also participated in a number of roadshows, including one in the last day. The TMC has fielded Mamata Thakur against BJP nomiee Shantanu Thakur inviting a split in the Matua community in the Bangaon (SC) seat. The CPI(M) has nominated Alakesh Das, while the Congress has fielded Sourav Prosad. Shantanu Thakur was injured in an accident on Saturday. Matua votes were considered a major factor in the
Trinamool Congress' win in the 2011 and 2016 Assembly polls. With an estimated population of 30 lakh in the state, Matuas can influence results in at least five Lok Sabha seats in North and South 24 Parganas districts.
