The November 25 bypolls to three Assembly seats in West Bengal will be the first litmus test for the TMC and the BJP since the Lok Sabha polls in the state.
The by-elections will be an indication of which way political winds are blowing in the State.
It will be the first electoral contest between the BJP and TMC since this year's parliamentary polls, in which the saffron party bagged 18 of the 42 Lok Sabha seats in the State, four less than that of the ruling Trinamool Congress.
The BJP is attempting to unseat the Mamata Banerjee Government from power in the State.
The bypolls are scheduled to be held in Kharagpur Sadar seat in West Midnapore district, Karimpur in Nadia and Kaliaganj in Uttar Dinajpur which are presently held by the BJP, TMC and the Congress respectively.
The Kaliaganj seat fell vacant after the death of sitting Congress MLA Parmathanath Roy while Kharagpur's BJP MLA Dilip Ghosh won the Medinipur Lok Sabha constituency.
TMC's Karimpur MLA Mahua Moitra emerged victorious from the Krishnnanagar Lok Sabha seat.
The by-polls ahead of the 2021 state Assembly election will have political ramifications in West Bengal as it will be held in the backdrop of the BJP's performance in the recent Maharashtra and Haryana assembly polls and in the shadow of the proposed implementation of NRC and tabling of the Citizenship (Amendment) Bill in Parliament.
For the BJP, the challenge is to live up to its performance in the parliamentary polls, whereas the TMC will try to regain its lost political ground.
The bypolls will also decide if the opposition Congress and the CPI(M), which have come together after three years, will remain relevant in the state politics or become redundant.
The Congress bagged two seats and the CPI(M) drew a blank in the 2019 Lok Sabha polls in the State.
As the BJP increased its tally from two seats in 2014 to 18 seats in 2019 by bagging 40.5 per cent votes, the TMC witnessed a massive slump in its number of seats down from 34 in 2014 to 22 this time.
"We are confident of winning all the three assembly seats in the bypolls. The people of West Bengal have made up their mind to defeat the TMC in 2021 Assembly polls in the state," West Bengal BJP president Dilip Ghosh told PTI.
According to a section of state BJP leaders, the party's failure to get the majority in Maharashtra and Haryana Assembly polls and a resurgent Congress in the northern state have not gone down well with its ranks in West Bengal.
"In the Lok Sabha polls, we had swept Haryana and Maharashtra. But in less than six months, the result of the Assembly polls shows that although Narendra Modi as Prime Minister is unchallenged at the national level, the same cannot be said for the state leaders when it comes to Assembly elections.
"So we are bit apprehensive that the same trend may not continue in West Bengal," a senior State BJP leader said on condition of anoynimity.
