Another Trinamool Rajya Sabha MP, Sushmita Dev, resigned from all party posts, making her the second Rajya Sabha MP from the party to do so this week.

And this is only the third day of the week.

"I do hereby resign from the membership of Rajya Sabha, which may please be accepted with immediate effect," the outgoing leader said in a letter addressed to Rajya Sabha chairman CP Radhakrishnan, who has accepted her resignation.

Shortly after her resignation, a picture of a smiling Sushmita Dev with Assam Chief Minister Himanta Sarma at his Delhi residence appeared online.

A picture is worth a thousand words. Within minutes of the news of Sushmita Dev's resignation from Rajya Sabha and Trinamool Congress, came her images with Assam Chief Minister Himanta Biswa Sarma. The two leaders smiling to the cameras. Images left little to imagination.

"There's only an Assam connection," a beaming Dev told the curious reporters after her surprise somersault.

Asked about her political future, Dev said she does not need anyone's validation and that her political choices "are hers to make".

Politics is unpredictable. Even more uncertain are manoeuvres when the political future appears bleak. Such is the case with one of Trinamool's most vocal MPs, Saayoni Ghosh, who now appears to be a surprise addition to the rebel camp.

Known for her pointed digs at rivals and the nicest remarks for party chief Mamata Banerjee, Ghosh is yet to speak out, but sources suggest she has already chosen her side amid what is playing out to be the Trinamool's biggest crisis since inception.

Asked about her meeting with Assam Chief Minister Himanta Biswa Sarma, Sushmita Dev said, "I took advice from him." 

"Today, I am a free woman. I have known Himanta da for long now; I paid a courtesy visit to him," she said.

Shortly after quitting Trinamool Congress, Sushmita Dev said that she does not want to be in "a situation where she is in two boats at the same time".

"It's a long story," said Sushmita Dev on why she quit Trinamool. She also said she does not want to comment on party chief Mamata Banerjee.

Sushmita Dev is the second Trinamol MP to resign this week. Earlier, Sukhendu Sekhar Ray had tendered his resignation from the party as well as the Rajya Sabha.

NDTV has accessed Sushmita Dev's resignation letter.

"I do hereby resign from the membership of Rajya Sabha, which may please be accepted with immediate effect. I convey my sincere gratitude to your Excellency, Hon'ble Deputy Chairman and all functionaries of the Rajya Sabha Secretariat extending all help and cooperation during my tenure as a Member of the Rajya Sabha," she wrote in a letter to Rajya Sabha chairman and Vice President CP Radhakrishnan.

Trinamool Congress' national general secretary Abhishek Banerjee held a meeting with Leader of Opposition in the Lok Sabha Rahul Gandhi in Delhi today. The meeting at 10 Janpath took place a day after Trinamool Congress president Mamata Banerjee met former Congress president Sonia Gandhi at her residence and discussed ways to further consolidate the opposition INDIA bloc.

Sushmita Dev, shortly after quitting Trinamool, met BJP's Himanta Biswa Sarma in Delhi.

Trinamool Rajya Sabha MP Sushmita Dev resigned from all party posts, making it the second Rajya Sabha MP from the party to do so this week.

The 53-year-old leader, who crossed over from the Congress and joined the Trinamool in 2021, spoke about starting a "new chapter of public service".

Kakoli Ghosh Dastidar - a four-term Parliamentarian who is now leading the contingent of Trinamool Congress's rebel MPs - was a founder member of the party and a close aide of former West Bengal Chief Minister Mamata Banerjee. Their ties go back to the '70s. Since Mamata Banerjee won her first election in 1984, Ghosh Dastidar has been her political aide.

Today she is leading a rebel group of more than two-third Lok Sabha MPs -- her action making it clear that at the end of the day, the decades old association with Mamata Banerjee is not enough to outweigh certain things.

Mamata Banerjee, a three-time former chief minister, remains in deep political peril as the Crime Investigation Department, or CID, arrived at her home in connection with a signature forgery case.

The 71-year-old leader is already battling a growing, and a very public rift, within the party.

Senior Congress leader Adhir Ranjan Chowdhury dismissed recent statements made by Trinamool Congress (TMC) leaders amid the growing turmoil within the party, describing the developments as a sign of frustration following political setbacks.

Reacting to Trinamool MP Kalyan Banerjee's remarks, Chowdhury said the demand and rhetoric surrounding fresh electoral contests were impractical and reflected political frustration.

"There is no point in talking like a mad person. This cannot happen. This is not some local village or neighbourhood wrestling match where if someone loses once, they can fight again after half an hour. It is certainly a contest, but not a village wrestling match. Elections cannot be held across the country in this manner...This is an expression of frustration," he told IANS.

Trinamool Congress leader Kirti Azad accused the rebels of betraying the party and preparing to join hands with the BJP.

"When BJP goons attack party workers, will you support them? This is betrayal. If you want to go to the BJP, say that openly," he said.

Targeting Kakoli Dastidar, Azad questioned her criticism of the party leadership and referred to the opportunities she had got within the organisation.

"Kakoli lost five elections, yet Mamata Banerjee made her an MP. You were removed as chief whip because you would not come to Parliament and would give instructions over the phone," he alleged.

The rebellion in the Mamata Banerjee-led Trinamool Congress has revived talk that the BJP-led National Democratic Alliance (NDA) government is likely to bring the Delimitation Bill again in the Monsoon session. 

On Monday, Trinamool MP Kakoli Ghosh Dastidar claimed to have the support of 20 party MPs in the Lok Sabha, one more than required to split the party as per the anti-defection law. The rebel MPs assembled at Union Minister Bhupender Yadav's home for a meeting. The Trinamool has 29 MPs in the Lok Sabha.

The 20 rebel MPs plan to form a bloc and support the NDA government at the Centre. If this materialises, it will push NDA even closer to the two-thirds majority mark.

Satabdi Roy, a four-time MP who has been by Mamata Banerjee's side since 2009, claimed that the former chief minister -- popularly known as 'Didi' -- had "changed" of late, a transition that did not go down well with her.

"Didi badal gayi thi," she remarked during an interview with NDTV. "She changed a lot in the past few years. I have an emotional connection with her, but what matters to me is the work, and hence I have taken this decision," she added.

Roy was chosen yesterday as the deputy leader of about a dozen Trinamool MPs who met with BJP leaders and offered to support the NDA, making it official that they wanted to part ways. Kakoli Ghosh Dastidar, who is now the rebels' chief whip, claimed the number of rebel MPs went up to 20.
