A faction of Trinamool Congress (TMC) lawmakers is considering defecting to the National Democratic Alliance (NDA) amid internal party rebellion [1].

This potential split threatens the stability of the TMC in West Bengal and further destabilizes the opposition INDIA alliance during a period of critical political realignment.

Reports indicate a divide between party leadership and a group of dissenting MPs. Senior TMC leader Kakoli Ghosh Dastidar said nearly 20 MPs are willing to join the NDA [1]. However, the camp surrounding Mamata Banerjee said 13 MPs are involved in the rebellion [1].

The scale of the defection is significant due to India's anti-defection laws. For a group of lawmakers to merge with another party without losing their seats, they must represent two-thirds of the legislative party. In this specific context, 19 MPs are required to bypass the law [1].

While the TMC faces internal strife, the broader INDIA alliance is struggling with coordination. A key meeting in New Delhi was missed by several members [1]. The DMK boycotted the proceedings over allegations that the Congress party betrayed the bloc [1].

The simultaneous collapse of party discipline in West Bengal and the fracturing of the national opposition alliance suggests a widening gap in the strategy of the non-NDA parties. The DMK's refusal to attend the New Delhi meeting marks a significant breakdown in communication between the alliance's primary partners [1].

The potential exit of 13 to 20 TMC lawmakers would fundamentally shift the power dynamics in West Bengal and weaken the INDIA bloc's numerical strength in Parliament. If the rebel faction reaches the 19-member threshold, they can legally merge with the NDA, providing the ruling coalition with a strategic foothold in a state traditionally hostile to them.
