Twenty rebel Members of Parliament from the Trinamool Congress (TMC) announced a merger with the Nationalist Citizens Party of India (NCPI) on June 14, 2024 [1].

This mass defection signals a deepening crisis for the TMC, which has held significant power in West Bengal since its founding in 1998 [7]. The move potentially shifts the balance of power in the Lok Sabha as these lawmakers seek closer alignment with the National Democratic Alliance (NDA) [3].

Following the announcement, the rebel lawmakers met with the Lok Sabha Speaker in New Delhi to request separate seating arrangements [2]. The NCPI, a regional party registered in 2023 [6], now absorbs a significant faction of the former TMC members.

The instability within the TMC extends beyond the federal legislature. Nearly 100 councillors have resigned from the party [4]. Additionally, reports indicate that 50 MLAs are in contact with the Bharatiya Janata Party (BJP) [5].

While some reports state 20 MPs announced the merger [1], other sources suggest up to 23 MPs have been in touch with the rebel camp [8]. Earlier claims also indicated that 20 TMC MPs were in contact with the BJP and ready to switch sides [5].

The internal rifts have prompted emergency leadership responses within the TMC to stem the tide of departures [8]. The rebels said an internal crisis was the primary driver for their decision to merge with the NCPI and move toward the NDA [3].

The departure of 20 MPs to a regional party like the NCPI creates a strategic bridge for TMC rebels to align with the NDA without immediately joining the BJP. This fragmentation weakens the TMC's legislative leverage and suggests a broader collapse of party discipline in West Bengal, potentially emboldening the opposition to challenge the party's regional hegemony.
