The two candidates are: Ambikesh Mahapatra, a professor of Jadavpur University, and Pratima Dutta, wife of slain Trinamool Congress leader from Howrah Tapan Dutta, former Supreme Court judge Ashok Ganguly said.
While Mahapatra would contest from Behala (east), Dutta would file her nomination from Domjur in Howrah.
Ganguly addressing reporters here said that people and democracy in the state were under attack.
The former SC judge, who was ousted from the West Bengal Human Rights Commission following a controversy, said that people were not being able to register their complaints even with the police.
Mahapatra, the convener of 'Aamra Aakranto', was arrested for circulating a cartoon on Facebook, soon after Dinesh Trivedi was asked to resign as Railway minister in 2012, which depicted a sequence from the famous Satyajit Ray film "'Sonar Kella', touching a raw nerve in the Trinamool Congress.
Dutta registered her protest against her husband's death which, she alleged, was the handiwork of the Trinamool Congress.
