Former CM and TMC chief Mamata Banerjee is facing a headache, that is too political. Trinamool Congress (TMC) seems to be experiencing one of its biggest internal crisis in its history. Just a few months after the disappointment of the West Bengal Assembly elections, former Chief Minister Mamata Banerjee has found herself facing a rebellion from within her own party. Almost 60 MLAs are backing the expelled leader Ritabrata Banerjee, which has raised a further worry whether the TMC is on the brink of a split.

What Triggered a Crisis inside TMC?

The issue at hand comes from a letter that is alleged to have forged the signatures of TMC MLAs for supporting the senior leader Sobhandeb Chattopadhyay as the Leader of the Opposition (LoP). The letter was reportedly filed by Ritabrata Banerjee and Sandipan Saha’s complaint before the Assembly Secretariat.

Within a few hours, the party officially expelled both legislators from the party for anti-party activities. But instead of putting an end to the crisis, it seems the TMC went further away from it.

How Big is the Rebel Group?

As per the rebels, they have a substantially big number of people backing them. The letter submitted by them to Assembly Speaker Rathindra Bose had signatures of almost fifty nine to sixty MLAs who have supported Ritabrata Banerjee to be the Leader of Opposition while reassuring Mamata Banerjee as the party leader.

The rebels insist they are not trying to form a separate political party. Instead, they claim to be working under the TMC banner while demanding changes within the legislative wing.

Their strength was visible when rebel MLAs arrived together at the Assembly and openly challenged the party leadership’s decisions.

Is TMC Heading Towards a Split?

While no formal split has been announced, the developments have triggered intense speculation. The rebellion comes amid growing signs of dissatisfaction within the party. Last week, a large number of TMC MLAs reportedly skipped a meeting called by Mamata Banerjee. Attendance at her recent protest programme was also significantly lower than expected.

Critics believe such a large-scale revolt rarely emerges overnight. Comparisons are already being drawn with the splits witnessed in the Shiv Sena and the Nationalist Congress Party, where months of internal resentment eventually led to major political realignments.

Abhishek Banerjee Also Under Pressure

The crisis worsened recently when the Enforcement Directorate summoned TMC national general secretary Abhishek Banerjee for questioning in the teachers’ recruitment scam. While this news came, senior leader and Mayor of Kolkata Firhad Hakim also resigned, the party found itself in an uncertain situation again.

What’s waiting for Mamata Banerjee?

For the present, Mamata Banerjee is the sole face of TMC. Yet the rebellion has revealed fissures in the party that are still healing from the blow of recent elections. If the claim of the rebel camp’s support from almost 60 MLAs proves correct, the crisis may turn into as big an event as Mamata’s political career, with big implications not only for Mamata Banerjee but also for TMC and politics in West Bengal.
