TMC Faces Existential Split as 20 Lok Sabha MPs Revolt Against Mamata Banerjee in Delhi

DELHI-KOLKATA— The ground beneath West Bengal’s ruling party hasn’t just shifted; it has split wide open. In a breathtaking escalation that has sent shockwaves from Kolkata to New Delhi, the Trinamool Congress (TMC) is facing an existential split. Just days after a massive mutiny in the state assembly, the rebellion has officially arrived in the national capital. On Monday, a staggering 20 of the party’s 29 Lok Sabha MPs held a strategy meeting at the Delhi residence of Union Minister and BJP’s West Bengal observer, Bhupender Yadav, signaling an imminent, catastrophic fracture in Mamata Banerjee’s fortress.

The rebel faction, spearheaded by veteran Barasat MP Kakoli Ghosh Dastidar, plans to break away to form a separate legislative bloc and throw its weight behind the BJP-led NDA government.

The Numbers Game: A Legal Coup?

For Mamata Banerjee and her nephew/General Secretary Abhishek Banerjee, the mathematics of this rebellion are devastating. By securing 20 out of 29 MPs, the rebel camp comfortably clears the two-thirds threshold required under the anti-defection law to avoid disqualification.

The Rebel Strategy

Dr. Kakoli Ghosh Dastidar, who was recently stripped of her position as TMC’s Chief Whip in the Lower House, insists she remains the whip “on paper.” Sources indicate she is preparing to present a letter bearing the signatures of all 20 rebel MPs to the Lok Sabha Speaker, formally requesting recognition as a separate entity.

The rebellion is a mirror image of events in Bengal last week, where nearly 60 of the TMC’s 80 MLAs revolted, electing Ritabrata Banerjee as the new Leader of the Opposition. Reaffirming the coordination between the state and central factions, Ritabrata Banerjee welcomed the Delhi developments, stating that both the MLAs and MPs are “guided by a common idea.”

High-Stakes Imagery and Key Defectors

The optics out of New Delhi on Monday left no room for ambiguity. Photographs from the Union Minister’s residence showed a gathering of political heavyweights, including West Bengal Chief Minister Suvendu Adhikari and former TMC Rajya Sabha MP Sukhendu Sekhar Roy, who recently resigned from both his party and parliament.

The 20-strong rebel roster includes several high-profile faces:

• Prasun Banerjee (Howrah)
• Satabdi Roy (Birbhum)
• Sharmila Sarkar (Bardhaman Purba)
• Jagadish Chandra Barma Basunia (Cooch Behar)
• Asit Kumar Mal (Bolpur)
• Anup Chakraborty (Bankura)
• Kalipada Soren (Jhargram)

In a frantic day of political maneuvering, CM Suvendu Adhikari later drove directly to Satabdi Roy’s Delhi residence to huddle with a core group of 10 rebel MPs, cementing the new alliance. Meanwhile, in Kolkata, former Mayor Firhad Hakim—a longtime Mamata loyalist who recently quit his civic post—was spotted meeting with rebel MLA leader Ritabrata Banerjee at the state assembly, hinting that backchannel talks or further defections may be underway.

The Pushback: “Yellow-Stained Pants” and Legal Posturing

Back in Kolkata, the remaining TMC high command is putting up a fierce, if bruised, defense. Party loyalists have launched a dual-pronged counteroffensive relying on legal technicalities and fierce rhetoric.

• The Legal Defense: Bardhaman-Durgapur MP Kirti Azad went public with a letter claiming that Dr. Dastidar’s faction is built on a lie. According to Azad, Mamata Banerjee had already informed the Lok Sabha Speaker last month that Dr. Dastidar was removed, and Kalyan Banerjee was appointed as the new Chief Whip. “The question is for how long the BJP will keep hoodwinking the people?” Azad questioned.
• The Firebrand Attack: Krishnanagar MP Mahua Moitra pulled no punches, taking to social media to torch her former colleagues. Reminding them that their 2024 mandates belonged to the TMC.

A fierce inner circle consisting of Sougata Roy, Kalyan Banerjee, Sudip Banerjee, Azad, and Moitra remains dug in behind the party chairperson.

The External View: “The Poacher Minister”

The political earthquake has also drawn sharp commentary from the broader opposition block. Congress General Secretary (Communications) Jairam Ramesh took a swipe at Union Minister Bhupender Yadav’s official portfolio on X (formerly Twitter):

“The Union Minister of Environment, Forests, and Climate Change who looked after elections in West Bengal has spent the day poaching. This Minister’s special job is to nab poachers and prevent poaching and not be one himself.”

Whether it is labeled “poaching” or a “democratic rescue mission,” the reality on the ground is irreversible. The TMC, which for over a decade projected an image of monolithic control over Bengal, is experiencing a historic, structural collapse. With the state assembly heavily compromised and the parliamentary party severed, Mamata Banerjee is facing the fight of her political life—not from the BJP outside, but from the ranks she built within.
