Is Trinamool Congress Falling Apart? The Crisis Inside Bengal's Ruling Party Explained

29 May 2026

Trinamool Congress (TMC), West Bengal's ruling political party under Chief Minister Mamata Banerjee, is going through what many are calling its deepest political crisis in years. Councillors are resigning by the dozen. Senior leaders are publicly airing grievances. BJP leaders are claiming defections are imminent. And the party that once looked unbreakable is now showing very visible cracks.

This is not just political noise. Something real is happening inside TMC, and it matters to anyone who wants to understand West Bengal's politics right now.


Why the TMC Crisis Is a Big Deal for West Bengal


West Bengal has been a TMC stronghold since Mamata Banerjee swept to power in 2011, ending the Left Front's 34-year rule. TMC has dominated elections, controlled civic bodies, and built its identity around Mamata's singular authority.

So when over 100 councillors across seven civic bodies resign within days of each other, when a sitting TMC Member of Parliament claims the party will be "finished in a few days," and when veterans openly accuse the leadership of overlooking corruption, something has shifted.

The timing matters. These mass resignations and public outbursts are happening right after a crushing electoral defeat in recent polls, where TMC underperformed significantly. Defeat has a way of loosening the bonds that hold a political party together.

What Is Actually Happening Inside TMC Right Now


Several threads are unravelling simultaneously.

First, TMC councillor resignations have hit civic bodies across Bengal at a pace that is hard to ignore. The Kolkata Municipal Corporation, the Bhadreswar civic body, and several others have seen chairpersons and elected representatives step down in quick succession. Some of these resignations come with no explanation. Others come with pointed statements.

Second, senior voices within the party are speaking publicly in ways that would have been unthinkable a year ago. Veteran Rajya Sabha MP Sukhendu Sekhar Roy used the word "anarchy" to describe the internal state of the party. Partha Chatterjee, a long-time TMC heavyweight, made explosive remarks claiming Mamata Banerjee "overlooked corruption" and raised pointed questions about Abhishek Banerjee, the Chief Minister's nephew who controls significant influence within the party.

Third, BJP leaders have been quick to exploit the situation. BJP MP Saumitra Khan claimed that 20 TMC MPs and 50 TMC MLAs are actively in contact with the BJP, ready to switch sides. TMC has dismissed these claims as "bogus," but the frequency and specificity of such allegations has raised eyebrows.

The RG Kar Shadow and the Internal Resentment


Much of the current anger within TMC traces back to the RG Kar Medical College rape and murder case from 2024, which shook Bengal deeply and triggered massive public protests. A sitting TMC MP recently said the party was "focused on covering up" the incident rather than seeking accountability, calling it a direct reason for their electoral loss.

That kind of public honesty from a party insider is rare. It signals that the dam holding internal frustrations in check has started to break.

There is also a growing perception within the party, voiced cautiously by several leaders, that a small inner circle around Abhishek Banerjee and the political consulting firm I-PAC had too much control over electoral strategy, and that veteran voices were being systematically sidelined.

What This Means for Bengal Politics Going Forward


The BJP has been trying to break into TMC's hold on Bengal for years. If even a fraction of the claimed defections materialise, it would fundamentally alter the political map ahead of the next state assembly elections.

Mamata Banerjee remains one of India's most experienced and resilient political leaders. Those who have written her off before have frequently been proven wrong. But the scale of the current internal revolt is different from previous episodes.

TMC's civic citadels, as one publication described them, are crumbling. Whether this becomes a full collapse or a managed crisis depends entirely on how Mamata responds in the coming weeks.

FAQs

What is Trinamool Congress (TMC)?

TMC is a regional political party founded by Mamata Banerjee in 1998. It has governed West Bengal since 2011 and is known for its strong grassroots network and Mamata's dominant leadership style.

Why are TMC councillors resigning in large numbers?

The resignations are happening primarily after a poor electoral performance. Internal frustration over corruption allegations, sidelining of senior leaders, and the handling of the RG Kar case are all contributing factors.

Who is Abhishek Banerjee and why is he controversial within TMC?

Abhishek Banerjee is Mamata Banerjee's nephew and a sitting TMC MP. He has become an increasingly powerful figure in the party's organizational structure, which some senior TMC veterans resent, feeling their own influence has been diminished.

Will TMC members actually defect to BJP?

As of now, no confirmed large-scale defections have happened. BJP claims of 50 MLAs and 20 MPs ready to switch are politically charged statements that TMC has denied. However, political situations can change rapidly.

What is the RG Kar case and why does it matter politically?

The RG Kar Medical College case involved the rape and murder of a trainee doctor in 2024, triggering large protests across Bengal. TMC's handling of the fallout is widely cited by insiders as a key reason for the party's poor showing in subsequent elections.

Can Mamata Banerjee recover from this crisis?

She has survived major political challenges before, including attempts by the BJP to unseat her in the 2021 state elections. Her ability to manage the current internal revolt will depend on whether she directly addresses the grievances of veterans and rebuilds trust within her own party ranks.
