Earthquake in TMC: Sushmita Dev’s sudden resignation from Rajya Sabha, is her entry in BJP certain or is a big political game going on? Two big resignations in a week – Is Mamata Banerjee’s grip weakening or is a big hidden rebellion coming to light within the party? Is there any organized strategy behind the claim of 20 MPs supporting NDA which is moving towards breaking TMC?
New Delhi/Kolkata: There has been an earthquake in the political empire of West Bengal Chief Minister Mamata Banerjee, which has put the very existence of Trinamool Congress (TMC) in danger. On Wednesday, June 10, 2026, veteran TMC leader and Rajya Sabha MP Sushmita Dev suddenly resigned from her post. After Sukhendu Shekhar Roy, she has become the second big leader to resign from the Upper House of Parliament in just a week. This dramatic incident has created a stir in politics from Delhi to Kolkata.
That suspense of 1 pm: Resignation submitted to the Vice President, apology to Mamata?
The story behind this step of Sushmita Dev is very shocking. According to sources, Dev will meet Vice President and Rajya Sabha Chairman C.P. at exactly 1 pm today. She will meet Radhakrishnan and officially submit her resignation. But the suspense does not end here. Inside sources claim that just before leaving the post, Sushmita Dev has also apologized to TMC chief Mamata Banerjee. Dev, who had a huge influence in Assam politics, finally realized that it was now impossible for her to stay on Assam’s soil through TMC or Congress.

Secret meeting with Assam Chief Minister: Will Rajya Sabha return again?
The biggest speculation in political circles is about what will be the next destination of Sushmita Dev? Quoting diplomatic sources, news has come that before taking the final decision of joining BJP, Dev had a very secret meeting with Assam Chief Minister Himanta Biswa Sarma. After this meeting, it is now believed to be completely certain that she will soon join Bharatiya Janata Party (BJP) and will once again return to Parliament through Rajya Sabha as a BJP candidate. Senior TMC leader Saugata Roy has also admitted with a heavy heart that Sushmita’s departure is a “huge blow” to the party.
After Sukhendu, now Sushmita, what is going on in TMC?
Just a week ago, TMC’s long-time chief whip in the Rajya Sabha, Sukhendu Shekhar Roy, had also surprised everyone by resigning. In his sharp letter, he had made serious allegations against the party like corruption, administrative failure and women’s safety. Now the sudden resignation of Sushmita Dev further strengthens the fact that everything is not normal within the party. The question is arising whether this is only the beginning and in the coming days more big names may distance themselves from TMC?

That scathing letter of Sukhendu Shekhar Roy: Which shook the roots of Mamata camp!
The story of how this spark of rebellion in TMC reached Parliament started a week ago. Sukhendu Shekhar Roy, who was the Chief Whip of TMC in Rajya Sabha for 13 years, had resigned by writing a very sharp and explosive letter to Mamata Banerjee. Sukhendu had written in his letter: “The people of Bengal have completely rejected the party’s rampant corruption, extreme oppression of women and massive anarchy in education, health, employment and law and order. For the first time in history, voters have given a massive victory to the BJP in terms of seats and the new government is busy in rebuilding Bengal.”

Kakoli Ghosh Dastidar’s big claim: 20 MPs are going to change sides!
This ongoing crisis within TMC is not limited to just two resignations, but has taken the form of a huge organizational rebellion. Rebel TMC MP Kakoli Ghosh Dastidar on Monday made a claim that shocked political pundits. According to Dastidar, at least 20 of TMC’s 28 Lok Sabha MPs are all set to support the National Democratic Alliance (NDA). This rebel group has also submitted a letter to Lok Sabha Speaker Om Birla. This rebel faction is being led by Kakoli Ghosh Dastidar himself and senior MP Shatabdi Roy has been made the deputy leader of this group.
Stirring in Delhi and TMC’s sharp counterattack: What next?
The direct impact of this rebellion is visible in the country’s capital also. Party MP Partha Bhowmik himself requested to move out of the government bungalow, considered the main center of TMC’s activities in New Delhi, and packed his bags and bedding from there on Tuesday. Meanwhile, seeing the increasing pressure, the TMC leadership has also taken a sharp stance. Senior party leader Kalyan Banerjee expressed his anger at the rebel group in a press conference. He said that the leaders who are unhappy with the party should morally resign from their posts immediately instead of making a public spectacle of the organisation.
After 61 MLAs standing in favor of rebel leader Ritabrata Banerjee and now claims of a split in the Parliament, Mamata Banerjee’s hold on her party seems to be completely weakening. Now it remains to be seen whether Mamata is able to stop this biggest disintegration, or is this fort of TMC about to collapse completely? The suspense has deepened.
