The veteran advocate withdraws from Abhishek Banerjee’s high-profile Calcutta High Court signature cases, refusing to be treated like an “employee of Camac Street.”
The institutional foundations of the ruling political layout in West Bengal have entered a phase of open, public civil war. Escalating months of backstage tension into a full-blown leadership challenge on Thursday, June 11, 2026, veteran Lok Sabha MP and senior advocate Kalyan Banerjee formally delivered a devastating Kalyan Banerjee ultimatum Mamata Abhishek decree. He demanded that party supremo Mamata Banerjee make an absolute choice between her long-standing loyalists or her nephew, National General Secretary Abhishek Banerjee.
The public confrontation brings the sharp generation gap within the Trinamool Congress (TMC) to a tipping point. Speaking to reporters following a dramatic legal clash over a signature forgery case at the Calcutta High Court, the four-time Sreerampur MP blasted Abhishek’s leadership style, calling him an “arrogant boy” who treats seasoned politicians like low-level staffers.
“I will remain in this party only if Abhishek is removed from all leadership positions and retained only as an ordinary worker,” Kalyan Banerjee declared. “Didi must take the final call on whether she will retain her blood relative or workers like me who have put in 40 years of our lives for her and this party.”

The Legal Spark: The High Court Representation Rift
The immediate breakdown of the relationship between the veteran legal mind and the party’s second-in-command centered around court strategy and personal respect. Kalyan Banerjee had spent the previous evening preparing a complex criminal revision petition to defend Abhishek in front of a Calcutta High Court vacation bench regarding a sensitive state police investigation into forged signatures.
Without informing the senior counsel, Abhishek’s inner circle independently assigned a parallel writ petition to a junior lawyer, bypassing the veteran completely. Kalyan Banerjee characterized this move as a severe professional insult, stating he would no longer protect the General Secretary across any judicial chambers.
“He thinks everyone is beneath him, as if everyone is merely an employee from Camac Street,” the MP noted, adding that he is a senior advocate known well into the Supreme Court and refuses to be treated like a disposal bin.
Tracking the Complete Collapse of the Ruling Assembly Bloc
This personal legal fallout matches an extensive, deep rebellion that has fundamentally rewritten the legislative map of West Bengal over the past month.
| Legislative Body Layer | Pre-May 2026 Party Baseline | Current June 2026 Broken Status | Immediate Balance of Power Impact |
| West Bengal Legislative Assembly | Held a strong, multi-seat ruling majority under the core party symbol. | 58 out of 80 MLAs rebel openly, forming an independent faction. | Expelled leader Ritabrata Banerjee is formally recognized as Leader of Opposition. |
| Rajya Sabha Parliamentary Bench | Maintained a high-profile, highly vocal opposition block in Delhi. | Three high-level resignations in 7 days (Ray, Dev, and Baraik). | Depletes the party’s national voting presence ahead of vital monsoon cycles. |
| Lok Sabha Parliamentary Bench | Unified regional representation team guiding national policy. | A group of 20 active MPs files a petition seeking separate seating grids. | Signals a complete, irreversible split within the party’s central core. |
The ongoing collapse was accelerated by a severe electoral defeat in the state assembly elections, which shattered the party’s long-standing monopoly over local government.
With 58 rebel legislators breaking away under the command of Ritabrata Banerjee to secure formal recognition from the Speaker as the principal opposition bloc, the central leadership’s ability to maintain discipline has evaporated.

Security Reductions and the Road Ahead
The veteran lawmaker also revealed that his state-allotted security detail has been abruptly and deliberately withdrawn, even as he faces consistent personal threats for opposing the General Secretary’s inner circle.
Banerjee has written directly to the Assembly Speaker to seek immediate protection, taking another direct swipe at his rival by stating that while Abhishek may be “the boss of Camac Street,” he is definitely not the boss of West Bengal.
The crisis is further complicated by a parallel exodus from the Rajya Sabha, where prominent MPs like Prakash Chik Baraik have resigned their seats to align with national opposition blocks.
As Mamata Banerjee holds emergency, closed-door meetings with senior national figures like Sonia Gandhi to find an external anchor for her career, her own domestic house is coming down around her.
Kalyan Banerjee has communicated his final terms through chief whip Derek O’Brien, leaving the ball entirely in the Chief Minister’s court. If she chooses family connections over her veteran organizers, the resulting split will permanently close an era of political history across the eastern capital.
FAQ Section
What caused the explicit Kalyan Banerjee ultimatum Mamata Abhishek crisis?
The internal crisis exploded after senior MP and advocate Kalyan Banerjee discovered that National General Secretary Abhishek Banerjee had secretly reassigned parallel High Court cases to a junior lawyer without consulting him. This professional insult prompted the veteran to withdraw from all of Abhishek’s personal legal matters and demand his removal from party leadership.
How deep is the ongoing legislative rebellion within the West Bengal Assembly?
The rebellion is deep and represents a functional split. Approximately 58 out of the party’s 80 elected MLAs have broke away from the main camp, successfully petitioning the Speaker to recognize expelled leader Ritabrata Banerjee as the official Leader of Opposition, reducing Mamata Banerjee’s direct control to a minority segment.
What are the terms Kalyan Banerjee laid down to remain within the party?
The four-time MP stated that he will remain with the Trinamool Congress only if Abhishek Banerjee is stripped of his executive leadership positions and kept strictly as a standard, ordinary worker. He emphasized that if the Chief Minister remains dependent on her nephew’s corporate aides, he will exit the party to chart his own political path.
