At least 20 rebel MPs from the All India Trinamool Congress (TMC) have announced they are joining the Nationalist Citizen Party of India [2].

This mass defection signals a significant shift in West Bengal's political landscape and potentially alters the balance of power within the Lok Sabha by strengthening the BJP-led National Democratic Alliance (NDA).

The group, led by Kakoli Ghosh Dastidar, chose the Tripura-based NCPI as their new political platform. The lawmakers submitted formal letters to Lok Sabha Speaker Om Birla in New Delhi to finalize the transition [1]. According to reports, the move stems from internal rifts within the TMC and growing dissatisfaction with the leadership of Mamata Banerjee [3].

Ghosh Dastidar said that two-thirds of TMC MPs have given a letter to the Lok Sabha Speaker for a separate seating arrangement [1]. This numerical shift represents approximately 66% of the party's parliamentary representation [1].

While the rebel MPs have pledged formal support to the NDA, the path to a direct merger with the BJP has appeared complicated. Samik Bhattacharya, the West Bengal BJP President, said that the door is closed for now [4]. This suggests a strategic decision by the rebels to align with a smaller party like the NCPI rather than seeking immediate induction into the BJP [2].

The NCPI, while lesser-known, provides a legal and political vehicle for the rebels to maintain their parliamentary standing while shifting their allegiance toward the NDA coalition [2]. The movement follows a period of escalating tension within the TMC, as members sought a new platform to distance themselves from the party's current direction [3].

"Two‑thirds of TMC MPs have given a letter to the Lok Sabha Speaker for a separate seating arrangement."

The migration of TMC legislators to the NCPI allows the BJP-led NDA to gain parliamentary support without the immediate political risk of absorbing dissidents directly into the BJP. By utilizing a third-party vehicle, the rebels avoid the immediate scrutiny of a direct merger while effectively neutralizing the TMC's influence in the legislature. This strategy highlights a tactical approach to coalition building in Indian politics, where smaller regional parties act as bridges for shifting allegiances.
