Turmoil in Trinamool: Twenty TMC MPs move to merge with Nationalist Citizens Party, pledge NDA support

A dramatic split in the Lok Sabha sees a two-thirds majority of Trinamool Congress members break ranks, threatening the party’s cohesion and signaling a massive shift in parliamentary arithmetic.

The corridors of power in Delhi witnessed a seismic shift this Sunday as Kakoli Ghosh Dastidar, leading a group of twenty rebel TMC MPs, confirmed plans to merge with the Nationalist Citizens Party. Emerging from a high-stakes meeting with Lok Sabha Speaker Om Birla, the faction made it clear that they intend to extend their support to the Bharatiya Janata Party-led National Democratic Alliance (NDA). For a party that prides itself on the monolithic control of Mamata Banerjee, this is perhaps the most significant internal challenge in years.

The mechanics of this move are deliberate. By claiming the support of twenty out of the party's 28 remaining members, the rebels are hitting the crucial two-thirds threshold required to bypass anti-defection complications. Sudip Bandyopadhyay, a senior figure among the dissenters, signaled that the group intends to lay formal claim to the "Trinamool Congress" name in July, leveraging their superior numbers to argue that they represent the authentic voice of the party.

A race against the clock

The announcement followed a frantic week of back-channel maneuvers. Earlier in the week, party National General Secretary Abhishek Banerjee moved to pre-empt the split, tasking Kirti Azad and Sagarika Ghose with delivering a formal letter to Speaker Birla. The directive was unambiguous: the TMC leadership insisted that the Speaker refuse to recognize any splinter group, maintaining that the party acts only through its officially authorized whip and leader.

As of now, the numbers game is creating a parliamentary impasse. The AITC, which secured 29 seats in the 2024 general elections, has seen its strength reduced following the vacancy caused by the death of the Basirhat MP. With twenty members now declaring their intent to sit separately, the Lok Sabha Speaker faces a procedural tightrope. The rebels have already submitted their written request, setting the stage for a bitter legal and legislative battle over the party’s identity and control.

Why it matters

The implications of this move extend far beyond the floor of the House. If the merger with the Nationalist Citizens Party gains legal standing, it fundamentally weakens the TMC’s bargaining power in national opposition circles and emboldens the NDA’s hold on the Lower House. This isn't merely a change in seating arrangements; it is a calculated attempt to dismantle the party from within.

The pattern here is clear: the rebels are banking on the two-thirds rule to provide a "clean" exit that avoids disqualification. However, by positioning themselves as the "real" party, they are setting up a protracted conflict over symbols and legitimacy. For the Trinamool leadership, the challenge is no longer just about managing dissent—it is about holding onto the party’s very existence in the face of a well-organized, high-stakes defection that threatens to redraw the political map of West Bengal.
