KOLKATA — In a dramatic escalation of internal strife within West Bengal’s ruling Trinamool Congress (TMC), veteran legislator Madan Mitra has abandoned Chief Minister Mamata Banerjee’s camp and joined a rebel faction led by expelled leader Ritabrata Banerjee. The defection, announced just 24 hours after the Enforcement Directorate (ED) summoned Mitra’s wife and sons in a money laundering probe, has sent shockwaves through the party, exposing deepening fractures ahead of critical state and national elections.
Mitra, a former state minister and one of the TMC’s most recognizable faces, sought to downplay the significance of his move, telling reporters on Tuesday, “I have only changed my room in the assembly. Nothing more, nothing less.” However, the timing of his defection—coming amid intensifying federal investigations into TMC leaders—has fueled speculation about a broader rebellion against Banerjee’s leadership. His alignment with Ritabrata Banerjee, a vocal critic of the chief minister, marks the most high-profile defection to the rebel faction since its formation in 2022.
What Happened
Mitra’s decision to switch allegiance was confirmed on May 14, 2026, a day after the ED issued summons to his wife, Archana Mitra, and sons, Subhro and Subhojit, in connection with an alleged money laundering case linked to a chit fund scam. The agency’s action is part of a wider crackdown on financial irregularities involving TMC leaders, including probes into land deals, government contracts, and Ponzi schemes that have plagued West Bengal for over a decade.
Mitra, who has been a TMC legislator since 2011 and previously served as transport minister, has himself been entangled in legal troubles. He was arrested in 2014 in connection with the Saradha chit fund scam—a multi-billion-rupee Ponzi scheme that collapsed in 2013, triggering political upheaval in the state. Though he was acquitted in that case in 2022, his family’s latest brush with the ED appears to have accelerated his break from Banerjee’s camp.
Ritabrata Banerjee, the 42-year-old former Rajya Sabha MP who now leads the rebel faction, welcomed Mitra’s move, framing it as a “step toward cleansing the party.” In a statement, Banerjee—who was expelled from the TMC in 2022 after publicly criticizing Mamata Banerjee’s leadership—accused the chief minister of “presiding over a culture of corruption and nepotism.” He claimed that Mitra’s defection was evidence of “growing disillusionment” within the party’s ranks.
The TMC, however, sought to minimize the fallout. Senior leaders loyal to Banerjee dismissed Mitra’s move as inconsequential, arguing that his influence had already diminished in recent years. “Madan Mitra was never a core leader. His defection changes nothing,” said a TMC spokesperson, speaking on condition of anonymity. The party’s official response has been to portray the rebel faction as a “fringe group with no mass support.”
Why It Matters
Mitra’s defection is more than a symbolic setback for the TMC—it represents a convergence of two existential threats to Banerjee’s leadership: internal dissent and federal investigations. The timing of his move, coming on the heels of ED summons to his family, suggests that the central government’s probes are not just targeting individuals but also destabilizing the party’s cohesion.
1. Federal Pressure as a Political Weapon
The ED’s actions against TMC leaders have long been viewed through a political lens, with the party accusing the Bharatiya Janata Party (BJP)-led central government of using investigative agencies to weaken opposition parties. Since 2021, the ED has summoned or arrested at least a dozen TMC leaders in cases ranging from chit fund scams to alleged irregularities in welfare schemes. Mitra’s case is particularly sensitive because it involves his family, a tactic critics say is designed to exert maximum pressure.
“The ED’s timing is never coincidental,” said a political analyst based in Kolkata, who requested anonymity. “When a senior leader’s family is targeted, it sends a message to others in the party: cooperate with the Centre, or face the consequences.” The BJP has denied allegations of political vendetta, insisting that the investigations are “purely legal matters.”
2. Rebel Faction Gains Momentum
Ritabrata Banerjee’s faction, though small, has positioned itself as a reformist alternative within the TMC, appealing to disgruntled leaders and grassroots workers frustrated with Banerjee’s centralized leadership style. Mitra’s defection could lend the rebels much-needed credibility, particularly if other mid-level leaders follow suit.
“Madan Mitra is not just another MLA—he’s a symbol of the old guard that built the TMC,” said a TMC insider who has been in touch with the rebel faction. “His move validates Ritabrata’s claim that the party has lost its way.” However, the rebels face an uphill battle: the TMC’s organizational structure remains tightly controlled by Banerjee, and defections to the BJP or other parties have historically been more common than internal rebellions.
3. Election Implications
With West Bengal’s panchayat elections due later this year and the 2026 state assembly polls on the horizon, Mitra’s defection could not have come at a worse time for the TMC. The party is already grappling with anti-incumbency sentiment after 15 years in power, and the BJP has been making inroads in urban and semi-urban areas.
“This is a body blow to the TMC’s narrative of unity,” said a poll strategist who has worked with multiple parties in West Bengal. “Every defection chips away at Mamata Banerjee’s image as an invincible leader. If more leaders jump ship, it could embolden the BJP’s campaign.”
Background and Context
The TMC’s current turmoil is rooted in a combination of historical grievances, legal troubles, and generational shifts within the party.
1. The Saradha and Rose Valley Scams
The TMC’s association with chit fund scams has been a persistent liability. The Saradha Group’s collapse in 2013, followed by the Rose Valley scam, left millions of investors defrauded and triggered a political storm. While Banerjee has sought to distance herself from the scandals, several TMC leaders, including Mitra, were directly implicated. The ED’s ongoing probes into these cases have kept the issue alive, providing the BJP with ammunition to attack the TMC’s governance record.
2. Central Agencies and the TMC’s Defiance
The TMC has long accused the Centre of weaponizing federal agencies like the ED, Central Bureau of Investigation (CBI), and Income Tax Department to target its leaders. Banerjee has led multiple protests against what she calls “political vendetta,” including a high-profile march to Kolkata’s ED office in 2021. However, the party’s defiance has not stopped the investigations, and the ED’s actions against Mitra’s family suggest that the pressure is only intensifying.
3. Ritabrata Banerjee’s Rebellion
Ritabrata Banerjee, a former student leader and Rajya Sabha MP, was once considered a rising star in the TMC. However, his public criticism of Banerjee’s leadership—particularly her handling of corruption allegations—led to his expulsion in 2022. Since then, he has sought to rally disaffected TMC workers under the banner of “TMC 2.0,” promising internal reforms. While his faction has struggled to gain traction, Mitra’s defection could be a turning point.
Competing Claims and Uncertainty
The TMC and the rebel faction have offered starkly different interpretations of Mitra’s move, reflecting the broader battle for narrative control.
– TMC’s Position: The party has sought to portray Mitra’s defection as a non-event, arguing that he was a marginal figure whose influence had waned. “He was never in the core decision-making group,” said a senior TMC leader. “This is just a desperate attempt by a few disgruntled elements to stay relevant.” The party has also accused Ritabrata Banerjee of being a “BJP stooge,” a claim he vehemently denies.
– Rebel Faction’s Claim: Ritabrata Banerjee’s camp has framed Mitra’s defection as the beginning of a larger exodus. “This is not about one leader—it’s about the future of the TMC,” said a rebel faction spokesperson. “Madan Mitra’s move proves that the party’s rank and file are no longer willing to tolerate corruption and autocracy.” The faction has also hinted at more defections in the coming weeks, though no names have been confirmed.
– Mitra’s Ambiguity: Mitra himself has been careful not to burn bridges with the TMC. While he has joined the rebel faction, he has not resigned from the party or the assembly. His statement about “changing rooms” suggests he may be keeping his options open, possibly in anticipation of a future reconciliation or a shift in political winds.
What to Watch Next
Mitra’s defection has set the stage for a series of critical developments in West Bengal’s political landscape:
1. Will More Leaders Follow?
The TMC is closely watching whether other mid-level leaders—particularly those facing ED or CBI scrutiny—will defect to the rebel faction or the BJP. “The next 72 hours are crucial,” said a TMC insider. “If two or three more MLAs join Ritabrata, it could trigger a domino effect.”
2. ED’s Next Moves
The agency’s investigation into Mitra’s family is expected to intensify, with potential raids or arrests in the coming weeks. The TMC has already announced plans to hold protests against “political vendetta,” but the party’s ability to mobilize support may be tested if more leaders come under scrutiny.
3. BJP’s Strategy
The BJP, which has been trying to consolidate its position in West Bengal, is likely to seize on the TMC’s infighting. “This is a golden opportunity for the BJP to portray the TMC as a sinking ship,” said a BJP strategist. The party may also attempt to woo disgruntled TMC leaders, though its own internal divisions in the state could limit its gains.
4. Mamata Banerjee’s Response
Banerjee, known for her combative style, is expected to take a hard line against the rebels. She has already begun reshuffling her cabinet and party organization to preempt further defections. However, her ability to hold the party together will depend on whether she can address the underlying grievances—particularly corruption allegations—that have fueled the rebellion.
Conclusion
Madan Mitra’s defection to the TMC’s rebel faction is more than a personal political realignment—it is a symptom of the deeper crises facing West Bengal’s ruling party. The convergence of federal investigations, internal dissent, and electoral pressures has created a perfect storm for the TMC, one that could reshape the state’s political landscape in the coming months.
For Mamata Banerjee, the challenge is twofold: she must contain the rebellion within her party while also countering the BJP’s narrative of a corrupt and crumbling TMC. The next few weeks will be critical in determining whether Mitra’s move remains an isolated incident or marks the beginning of a larger unraveling.
For the rebel faction, the task is equally daunting: proving that they can offer a viable alternative to Banerjee’s leadership without being dismissed as a fringe group. Mitra’s defection has given
