Trinamool Congress (TMC) leader and former Rajya Sabha MP Dr Santanu Sen on Thursday reportedly resigned from the post of party spokesperson, a development that comes a day after Mamata Banerjee’s Kakoli Dastidar Ghosh resigned from all her posts.

Citing the rape, murder and corruption case in 2024, Santanu Sen’s resignation, addressed to party president Mamata Banerjee, stated that his mind no longer agrees to support the party as national spokesperson on “immoral acts”.
“…Though I did not agree with the views during various difficult times, I have openly fought for the party in the media on many controversial issues, which the common people have often spoken highly about. But in the present situation, when the people of Bengal have rejected us for so many unethical acts and corruption, including RG Kar case, Abhaya case, money for job corruption, my mind no longer agrees to support them as spokesperson in any way. Therefore, I want to resign from the post of All India Trinamool Congress Spokesperson, “Taking into consideration the judgment of the people, I ask that my resignation be accepted and respected.”
A day earlier, TMC MP Kakoli Ghosh Dastidar resigned from the post of president of the party’s women’s wing. In her resignation letter, she said that the party had failed to protect her from abuse by a colleague in Parliament, in an indirect reference to Kalyan Banerjee.
Banerjee also replaced her as chief whip of Trinamool Congress in Lok Sabha.
While Ghosh Dastidar has increasingly distanced herself from the party by stepping down from key organizational posts, the complaint against her colleague Kalyan Banerjee has opened a new front in the internal turmoil within the embattled Trinamool Congress.
Former Prime Minister Mamata Banerjee-led TMC lost power to the Bharatiya Janata Party (BJP), which won a wide mandate in the recently concluded 2026 West Bengal state elections. The BJP won 207 of the 293 seats counted on 4 May, and also won the Valta constituency, where re-polls were held on 21 May.
Kakoli Ghosh Dastidar on Thursday sought permission from Lok Sabha Speaker Om Birla to file a formal complaint against his party colleague Kalyan Banerjee, accusing him of misogyny and repeated verbal abuse.
In a letter to Birla, cited in an earlier HT report, Dastidar alleged that Banerjee “repeatedly verbally abused” her inside the Lok Sabha chamber. She further wrote that “this misogyny was directed against many members and they should be punished.”
On Wednesday, Kalyan Banerjee lashed out at Kakoli Ghosh Dastidar, reminding the media of her alleged acceptance of… $5 lakh in the Narada sting operation and accused of supporting illegal syndicates involved in supply of raw materials in Kolkata.
