A growing rebel camp within the Trinamool Congress has emerged after senior leader Kalyan Banerjee publicly criticized Abhishek Banerjee on Thursday.

The public friction between a veteran party stalwart and the nephew of Chief Minister Mamata Banerjee suggests a deepening internal crisis for the party. This instability threatens the unity of a political organization that has maintained a tight grip on West Bengal for over a decade.

Kalyan Banerjee described the ongoing criticism directed at Abhishek Banerjee as "a great humiliation to me," he said [1]. The comments highlight a rift between the party's old guard and the newer leadership structure centered around Abhishek Banerjee.

For 15 years, Mamata Banerjee and the TMC have maintained an untouchable status in the region [1]. This dominance is reflected in the party's record of three consecutive Assembly election wins [1]. Furthermore, the TMC has remained the single-largest party in four straight Lok Sabha polls [1].

Despite these electoral successes, the current dissent indicates an existential struggle. The emergence of a rebel faction suggests that previous electoral dominance may no longer be enough to suppress internal grievances, or power struggles.

Chief Minister Mamata Banerjee now faces the challenge of managing these conflicting factions. The tension between the veteran leadership and the party's second-in-command creates a volatile environment within the political base of West Bengal.

"It is a great humiliation to me."

The public nature of Kalyan Banerjee's criticism marks a shift from private disagreement to open rebellion. After 15 years of undisputed control, the Trinamool Congress is experiencing a breakdown in internal discipline. This friction between the party's established veterans and the ascending leadership of Abhishek Banerjee could weaken the party's cohesion ahead of future electoral cycles.
