A rebel faction of the Trinamool Congress has filed a letter with the Lok Sabha Speaker seeking separate seating in Parliament.

This move threatens the stability of the party in West Bengal and could shift the balance of power within the lower house of India's Parliament. The split comes amid internal disputes over party leadership and administration.

Between 20 [1] and 23 [2] members of parliament are reportedly aligned with the rebel camp. The faction is led by Kakoli Ghosh Dastidar, and the group has named Ritabrata Banerjee as the leader of the opposition for their wing. The rebels have gone beyond seeking separate seating by claiming to be the real party.

The breakaway group said the party is not functioning according to its constitution. They also alleged misgovernance within the organization as the primary driver for their decision to seek independent status [1, 4].

To operate independently and avoid a forced merger under parliamentary rules, a faction must typically secure a two-thirds majority of the party's parliamentary strength [3]. The current number of rebels remains below this threshold, creating a complex legal and political standoff regarding their official status in the Lok Sabha.

Chief Minister Mamata Banerjee has called an emergency meeting to address the crisis [2]. The rebellion marks a significant challenge to the party's cohesion in its stronghold of West Bengal, as the faction seeks to establish a separate identity from the central leadership.

The rebels have gone beyond seeking separate seating by claiming to be the real party.

The split in the Trinamool Congress highlights a deepening rift between the party's central leadership and a significant bloc of its lawmakers. Because the rebel faction has not yet reached the two-thirds majority required to avoid a merger or disqualification under anti-defection laws, the outcome will likely depend on whether more MPs join the rebellion or if the leadership can negotiate a reconciliation. This instability may weaken the party's leverage in New Delhi and open the door for opposition parties to gain ground in West Bengal.
