A list of 19 rebel Trinamool Congress (TMC) MPs has emerged amid a deepening internal crisis within the party, marking one of the biggest parliamentary challenges to Mamata Banerjee’s leadership in recent years. The group, reportedly led by senior MP Kakoli Ghosh Dastidar, submitted their names to Lok Sabha Speaker Om Birla’s office, signalling a potential formal split and raising questions over compliance with the anti‑defection law. Political analysts say the revolt could reshape party dynamics and influence alliances ahead of future elections.

Names of 19 Rebel TMC MPs Surface
A major political upheaval has surfaced within the Trinamool Congress (TMC) as 19 of the party’s 28 Lok Sabha MPs are reported to have aligned with a rebel faction and submitted their names to Lok Sabha Speaker Om Birla’s office. The list includes notable figures such as Kakoli Ghosh Dastidar (Barasat), Yusuf Pathan (Berhampore), Saayoni Ghosh (Jadavpur) and Shatrughan Sinha (Asansol) among others.
The rebel MPs are said to be pursuing separate seating arrangements in Parliament, a step widely interpreted as a bid to establish an independent group distinct from the official TMC parliamentary party.
Who Are the Rebels?
According to sources, the 19 MPs reported to be part of the rebel group include:
- Kakoli Ghosh Dastidar (Barasat)
- Jagadish Chandra Basunia (Cooch Behar)
- Yusuf Pathan (Berhampore)
- Saayoni Ghosh (Jadavpur)
- Shatrughan Sinha (Asansol)
- Satabdi Roy (Birbhum)
- Mala Roy (Kolkata South)
- Deepak Adhikari (Ghatal)
- Rachana Banerjee (Hooghly)
- Mitali Bag (Arambagh), among others.
This group represents a significant section of the TMC’s Lok Sabha strength and is pushing for a formal recognition separate from Mamata Banerjee’s leadership a move that could fundamentally alter parliamentary representation for the party.
Political Context: Why the Rebellion?
The crisis has its roots in the TMC’s recent defeat in the West Bengal Assembly elections, where the party lost power after 15 years of dominance. Internal dissatisfaction and factional disputes escalated quickly, leading to a wave of defections, resignations and rebellion within both the legislative and parliamentary wings.
Adding to the turmoil, three Rajya Sabha MPs have resigned from the party in a short span, including senior leaders like Sushmita Dev and Sukhendu Sekhar Ray, signalling discontent at different levels of the party hierarchy.
Legal and Strategic Implications
Under India’s anti‑defection law, a party’s MPs can be disqualified if they defect from their political party. However, if a group comprising at least two‑thirds of the party’s legislators breaks away together, they may avoid automatic disqualification and be recognized as a separate group. Analysts note that with 19 out of 28 Lok Sabha MPs allegedly backing the rebellion, the rebel faction may meet the threshold needed to circumvent disqualification.
Political strategists say this “Maharashtra Model,” where a large group breaks away to form its own identity within Parliament, could reshape how factions realign and how future alliances are formed.
Party Leadership Under Pressure
The wave of rebellion has intensified scrutiny on party chief Mamata Banerjee’s leadership. Veteran leader Babul Supriyo, however, has publicly expressed his loyalty, calling it “inappropriate to abandon a ship in troubled waters” and reiterating support for Banerjee despite defections.
Meanwhile, opposition parties like the Bharatiya Janata Party (BJP) are said to be poised to benefit from the TMC’s internal turmoil, with political commentators suggesting the revolt could bolster the BJP‑led National Democratic Alliance (NDA) in Parliament.

Broader Political Fallout
The rebellion has stirred intense speculation about larger political realignments, with some rumours suggesting possible talks of alliance or merger with the Indian National Congress though the Congress has officially dismissed such merger claims as “totally baseless.”
Political experts say the crisis could reverberate beyond Bengal, affecting national party strategies and coalition mathematics ahead of future elections.
What’s Next for TMC?
The rebel MPs’ move to seek separate recognition from the Lok Sabha Speaker could set a precedent for similar fractures in national parties. Meanwhile, Mamata Banerjee and her loyalists are expected to respond with organisational restructuring and efforts to keep the remaining MPs aligned.
With tensions escalating and legal battles over recognition and anti‑defection safeguards looming, the TMC’s parliamentary future remains uncertain and its internal crisis is now a matter of national political importance.
