BJP state president Sudhindra Chandra Dasgupta, Trinamool Congress's state chief Ratan Chakraborty, a former Congress minister, Tripura Pragatishil Gramin Congress (TPGC) president Subal Bhowmik and Aam Aadmi Party's Salil Saha, a physician, are the other aspirants.
Both Chakraborty and Bhowmik, former Congress legislators, left the party last year and formed Tripura unit of the Trinamool and TPGC respectively.
The Left has won from West Tripura 11 times since the first Lok Sabha election of 1952 and the Congress four times. The Congress For Democracy, a breakaway faction of the Congress, secured the seat in 1977.
