BJP had made history by winning an Assembly seat in West Bengal then. The seat gave BJP its only MLA in the state in 15 years - Samik Bhattacharya.

11. The triangular contest between Chief Minister Mamata, Congress' Deepa Dasmunshi and BJP's Chandra Bose was one to watch out for. While most political pundits said Dasmunshi and Chandra Bose had a difficult task cut out for them as defeating Banerjee, who was contesting for a second run as CM, is next to impossible.

Banerjee had chosen Bhabanipur as her constituency after becoming the chief minister in 2011. TMC leader Subrata Bakshi vacated the seat for her. She won the by-polls with a huge margin, winning close to 78 % of the vote share.

However, BJP did pull off a good show in Kolkata South in 2014, coming second to TMC. 295,126 votes were polled in favour of BJP candidate Tathagata Roy, currently the Governor of Tripura.

12. CPI(Marxist)'s Sujan Chakraborty fought it out with TMC's Manish Gupta from Jadavpur. Chakraborty had won the 2014 Lok Sabha elections from the constituency.

13. The hot-bed of land rights movement against Tata Nano factory in Singur had played a huge role in helping Mamata Banerjee overthrow the over three-decade rule in West Bengal. From this seat, sitting MLA and TMC minister Rabindranath Bhattacharjee was up against CPI(M)'s Rabin Deb and BJP's Suren Patra.

14. Partha Chatterjee won the Behala Paschim constituency seat since 2001 and hopes to win this year as well. His opponent is CPI(M)'s Kaustav Chaterjee.

His opponents were the Left Front's Rashid Gaji and BJP's Abani Kumar Mandol.
