Twenty Trinamool Congress (TMC) Lok Sabha members wrote to Speaker Om Birla on June 8, 2024, declaring support for the BJP-led National Democratic Alliance [1].

This move signals a potential split within the party's parliamentary unit. By seeking a separate bloc and seating arrangement, the rebel faction threatens to diminish the TMC's influence in the lower house while strengthening the ruling coalition's numbers.

The group is led by Chief Whip Kakoli Ghosh Dastidar [1]. In their communication to the Speaker's office in New Delhi, the lawmakers requested a distinct seating area in Parliament [2]. This faction alleges mis-governance in West Bengal and seeks alignment with the BJP to address these issues [2].

While 20 MPs have formally written to the Speaker [1], other reports suggest the crisis is deeper. Some sources said that as many as 23 MPs are currently in touch with the rebel camp [3].

The shift occurs as the party faces internal turmoil regarding its leadership and administration in West Bengal. The rebel MPs have moved to distance themselves from the main party line, a step that could trigger formal disqualification proceedings under anti-defection laws if the split is not recognized as a legal merger or a significant break.

Representatives from the rebel camp have focused their grievances on the state of governance in West Bengal [2]. The move to align with the NDA represents a significant pivot for lawmakers who were elected under the TMC banner.

The defection of a significant bloc of MPs from the TMC to the NDA could destabilize the party's standing in the Lok Sabha and embolden the BJP's position in West Bengal. Because the rebels are seeking separate seating rather than immediate resignation, the outcome depends on whether Speaker Om Birla recognizes the faction as a legitimate split or treats the move as a violation of the Tenth Schedule of the Indian Constitution, which governs party defections.
