Barrackpore MLA Shilbhadra Dutta, on Friday, quit the Trinamool Congress. This constitutes the third major exit from the party in two days after Suvendu Adhikari and Paschim Bardhaman MLA Jitendra Tiwari. Following their departure, many other dissident leaders and party workers quit after Adhikari's exit.

Ahead of the West Bengal Assembly election, these resignations may prove to be a big blow for Banerjee as she seeks a third term as chief minister early next year.

"I think that I am unfit in the party in the present scenario. But, I will not resign as an MLA," he told reporters.

"Why should I resign as an MLA? I have won by people's votes. If I go (resign) away, where will they go?" he added.

Over the last few months, Dutta has been vocal about his opposition to election strategist Prashant Kishor and the way he was handling party affairs.

Dutta, once a Mukul Roy loyalist when the BJP leader was in Trinamool Congress, has also spoken against a section of the party's leadership.
