While the Bharatiya Janata Party (BJP) is yet to declare the names of candidates for the upcoming bypolls.
The sources say that Alpesh Thakor will file his nomination from Radhanpur on September 30 at around 1.43 pm.
Thakor had resigned from the Radhanpur seat earlier in the year, after he and his supporter Dhavalsinh Zala, voted for BJP in the Rajya Sabha election.
Both Thakor and Zala had won the Radhanpur and Bayad seats respectively on a Congress ticket.
After Thakor's resignation from Congress, it has been a foregone conclusion that he would be repeated from the same seat on a BJP ticket, but the party is known to pull a surprise at the last moment.
