The Revolt Mamata Banerjee Refuses to See

In the first week of June, as her party was coming apart, Mamata Banerjee named the cause ^[1].

A conspiracy has been hatched from Delhi to split the TMC. But we will not allow it to happen. We will fight. — Mamata Banerjee

On the same timeline, from inside her own camp, a different diagnosis arrived. Senior MP Kalyan Banerjee — a Mamata loyalist, not a rebel — issued an ultimatum demanding she choose between him and her nephew Abhishek ^[2].

I will not appear for Abhishek Banerjee in any case in coming days because I do not like his arrogant attitude. — Kalyan Banerjee

Two voices from the same party, describing opposite things about what is killing it. The gap between them is not just a disagreement. It is the reason the Trinamool Congress is now several steps into the same sequence that erased the Shiv Sena as an independent force — and the reason its leader cannot see it. The BJP's institutional campaign against the TMC is real, and Mamata Banerjee is not wrong to name it. In May, weeks before the mass defections began, new BJP Chief Minister Suvendu Adhikari publicly flagged Abhishek Banerjee for legal action on corruption charges ^[3]. In June, the Enforcement Directorate questioned Abhishek for eleven hours ^[4]. The Assembly Speaker recognized the rebel faction's claim to the Leader of the Opposition post, a move the Calcutta High Court is now weighing ^[5][6]. In July, rebels seized the party's Kolkata headquarters — a takeover shielded, by the rebels' own account, by the Central Reserve Police Force, a central force under the BJP government's control ^[7]. Days ago, the state government demolished Abhishek's party office in Amtala during an anti-encroachment drive ^[8]. And on June 29, the BJP government passed a law allowing preventive detention of up to twelve months without trial and confiscation of assets — a legal infrastructure deployable against TMC members and their property ^[9]. Central-agency pressure and legislative recognition of rebels are the instruments familiar from Maharashtra. Bengal adds physical takeover of party property and a bespoke preventive-detention law on top of that template. This is not passive opportunism. It is a systematic state campaign. But the campaign did not create the fault line it is exploiting. The rebels' own stated grievance has almost nothing to do with Delhi. When 58 MLAs broke away in early June, they framed their move as a fight against "individual cult" and "ruthless dynastic politics" centered on Abhishek Banerjee ^[1].

My whole fight is against the individual cult and the ruthless dynastic politics that have slowly taken away the essence of the grassroots party. — Ritabrata Banerjee

The rebels maintained allegiance to Mamata and requested her as chief advisor. What they rejected was her nephew's authority — a dynastic succession grievance that even Kalyan Banerjee, the loyalist who demanded she choose, confirmed when he said Abhishek's "arrogant attitude" had cost them the election ^[2]. The anti-Abhishek resentment was not a rebel invention. It pervaded the party. Mamata Banerjee's response to this internal crisis was to treat it as an external one. In early June, as the rebellion crystallized, she led street protests against the BJP, accusing it of rigging 177 of 294 seats, and expelled dissident MLAs for anti-party activities ^[10]. When rebels seized the party headquarters in July, she attributed it entirely to BJP direction: "At the BJP's behest, they have betrayed the party" ^[7]. The pattern was consistent: every internal fracture was met with external protest and internal expulsion. Reform — of the succession structure, of the role of the consultancy I-PAC, of the dynastic grip the rebels explicitly named — was never on the table. The BJP understood what Mamata would not. On June 16, BJP MP Rahul Sinha declared the party was staying out of the TMC's internal fight.

We are not going to get involved in the TMC's fight. — Rahul Sinha

That same day, the Enforcement Directorate questioned Abhishek Banerjee for eleven hours ^[4]. The dual character of the BJP's approach — rhetorical non-interference paired with active institutional pressure — is not a contradiction. It is the method. The state does the work; the party disowns it. And the work succeeds because the target party's leader, by treating all dissent as conspiracy, forecloses the internal reform that might have held the party together. The TMC is now several steps into the same sequence that dismantled the Shiv Sena. Twenty of its 28 Lok Sabha MPs have merged with a Tripura-based party to support the NDA, the same two-thirds threshold tactic used in Maharashtra ^[11]. The rebel faction has petitioned the Election Commission to claim the party name, bank accounts, and symbol ^[7]. The courts are weighing whether the Speaker's recognition of the rebel Leader of the Opposition was legal ^[6]. The outcome is not settled, but the machinery is familiar. Uddhav Thackeray reached for the same narrative when his party fractured.

Shiv Sena, headed by me, is the only Shiv Sena. — Uddhav Thackeray

He, too, framed the split as externally engineered rather than internally driven. He, too, claimed to be the sole legitimate leader. The Shiv Sena is now gone as an independent force — Amit Shah declared in June that "there is only one Shiv Sena, which is headed by Eknath Shinde" ^[12]. The TMC's internal grievance — the dynastic succession question — is different from anything that drove the Shiv Sena split. But the framing choice is identical, and so is its consequence: a leader who cannot distinguish between a genuine internal revolt and an external assault cannot address either. The narrative that makes the party's persecution visible is the same one that makes its cure invisible.
