TMC MPs Support NDA, Trigger Major Political Shock

A major political development unfolded on Monday as nearly 20 Trinamool Congress (TMC) Lok Sabha MPs reportedly extended support to the National Democratic Alliance (NDA), signalling a significant split within the party’s parliamentary unit. The development comes just weeks after the TMC’s poor performance in the 2026 West Bengal Assembly elections and has intensified speculation about the future of Mamata Banerjee’s party at the national level.

According to reports, the rebel MPs have written to Lok Sabha Speaker Om Birla, informing him of their decision to function as a separate bloc while supporting the NDA on key parliamentary and political issues. If recognised, the move could substantially alter parliamentary equations in the Lok Sabha.

The development is being viewed as one of the most serious internal challenges faced by the Trinamool Congress since its formation.

Kakoli Ghosh Dastidar Leads Rebel Group

The rebellion is reportedly being led by senior TMC MP and former Chief Whip Kakoli Ghosh Dastidar. Sources indicate that around 20 MPs from the party’s Lok Sabha contingent of 28 members have aligned with the faction.

Reports also suggest that actor-turned-politician and TMC MP Shatabdi Roy has been proposed as the deputy leader of the rebel group. The faction has argued that recent political developments in West Bengal and the mandate delivered by voters require a reassessment of the party’s political direction.

The group is understood to have informed the Speaker about its intention to operate separately from the existing Trinamool Congress parliamentary leadership while backing the NDA on major issues. The TMC MPs Support NDA development is being viewed as one of the biggest challenges faced by the Trinamool Congress in recent years.

TMC MPs Support NDA After Bengal Election Defeat

The decision comes in the aftermath of the West Bengal Assembly elections held in May 2026, which resulted in a significant setback for the Trinamool Congress. The BJP secured a decisive victory, winning 207 seats, while the TMC was reduced to 80 seats.

Rebel MPs have reportedly cited the electoral verdict as one of the key reasons behind their decision. According to their position, the election results reflected public dissatisfaction with the party’s current leadership and strategy.

Political observers believe the defeat created deep divisions within the party, with several leaders questioning the direction of the organisation after years of dominance in West Bengal politics.

Impact on NDA’s Strength in Lok Sabha

If the Speaker recognises the rebel faction and its support for the NDA, the development could have important implications for parliamentary arithmetic. Estimates suggest the NDA’s strength in the Lok Sabha could rise from 293 seats to approximately 313 seats.

Such a development would further strengthen the ruling alliance’s position in Parliament and reduce the influence of opposition parties in key legislative matters.Political analysts believe the TMC MPs Support NDA move could significantly reshape parliamentary dynamics in the coming months.

The parliamentary significance of the move has attracted attention across the political spectrum, with analysts closely watching how constitutional and procedural aspects of the development are handled.

No Official Response from TMC Leadership Yet

As of Monday evening, the Trinamool Congress leadership had not issued an official response to the reports. The TMC MPs Support NDA development has intensified speculation about the future direction of the party following its recent electoral setback in West Bengal. The absence of an immediate statement has fuelled further speculation regarding the scale of the internal crisis facing the party.

Political commentators note that the reported support extended by nearly 20 MPs represents a substantial portion of the party’s Lok Sabha representation and could significantly weaken the TMC’s position in national politics if the split formalises.

The coming days are expected to be crucial as both the Speaker’s office and the Trinamool Congress leadership assess the implications of the MPs’ move.

What Happens Next?

The future course of events will largely depend on parliamentary procedures and whether the Speaker recognises the faction’s claim. Questions regarding anti-defection provisions, parliamentary recognition, and organisational control of the party are also likely to emerge.

For now, the development marks a dramatic escalation of internal tensions within the Trinamool Congress and represents a significant boost for the NDA at a time when political alignments across several states continue to evolve. The TMC MPs Support NDA issue is expected to remain a major talking point in national politics as the situation continues to unfold.

As the situation develops, all eyes will remain on New Delhi and Kolkata, where the political fallout of the reported rebellion is expected to shape discussions in both Parliament and West Bengal politics.
