Kolkata: The Trinamool Congress (TMC), once considered politically invincible in West Bengal under Mamata Banerjee, is now facing its deepest internal crisis after losing power to the BJP in the 2026 Assembly elections. What began as isolated dissent has now snowballed into a full-scale rebellion stretching from the Bengal Assembly to Parliament.

The biggest shock came after reports emerged that over 20 dissident TMC MPs had written to Lok Sabha Speaker Om Birla expressing their willingness to align with the NDA. The development came just hours after senior TMC leader and Rajya Sabha MP Sukhendu Sekhar Ray resigned from both Parliament and the party.

Cracks Began Emerging After Election Defeat

The TMC’s troubles started immediately after the BJP’s landslide victory in Bengal. Mamata Banerjee herself lost the prestigious Bhabanipur seat to former aide-turned-BJP leader Suvendu Adhikari.

Soon after the results, several party leaders openly criticised the leadership style within TMC and blamed corruption, inaccessibility and internal mismanagement for the crushing defeat. Discontent rapidly spread across the organisation, with resignations from senior leaders, municipal councillors and party office-bearers.

The crisis deepened when nearly 60 out of 80 TMC MLAs reportedly skipped a key meeting called by Mamata Banerjee at her residence, signalling growing mistrust within the party ranks.

Ritabrata Banerjee Emerges As Face Of Revolt

The rebellion escalated dramatically when 58 TMC MLAs backed Ritabrata Banerjee as the Leader of Opposition in the Bengal Assembly, rejecting the party’s official nominee. The Assembly Speaker later recognised his claim, dealing a massive blow to Mamata Banerjee’s authority.

Ritabrata Banerjee has since intensified attacks on Abhishek Banerjee, accusing him of promoting dynastic politics and damaging the party’s image.

Crisis Reaches Delhi

The turmoil is no longer limited to Bengal. During the INDIA bloc meeting in Delhi, rebel MPs reportedly held parallel discussions with senior BJP leaders, fuelling speculation of a major split within TMC.

While Mamata Banerjee still commands personal loyalty among sections of the party, the rapid pace of rebellion has raised serious questions over the future of the Trinamool Congress and its leadership structure.
