Kalyan Banerjee, a senior Member of Parliament and advocate for the Trinamool Congress (TMC), has launched a public attack on party leader Abhishek Banerjee [1].

The rift signals a deepening crisis within the TMC leadership in West Bengal. Because Kalyan Banerjee is both a high-ranking politician and a legal representative, his refusal to support Abhishek Banerjee—the son of Chief Minister Mamata Banerjee—creates a visible fracture in the party's internal hierarchy [1, 2].

Banerjee cited disagreements over leadership style as the primary driver of the conflict. He said that the party is facing growing troubles due to the behavior of the younger leader [2, 3].

"His arrogance is responsible for the party’s growing troubles," Banerjee said [2].

The dispute has extended beyond political strategy into professional legal services. Kalyan Banerjee, who often provides legal counsel for party members, explicitly distanced himself from Abhishek Banerjee's future legal needs [1].

"I will not appear for Abhishek Banerjee in any legal matter," Banerjee said [1].

This public confrontation occurs in Kolkata, where the TMC maintains its primary power base [1]. The accusations of arrogance suggest a growing resentment among the party's veteran guard toward the leadership transition involving the Chief Minister's son [2, 3].

While the TMC has faced internal challenges previously, the nature of this revolt is distinct due to the seniority of the critic. Kalyan Banerjee's role as an advocate makes his refusal to provide legal representation a significant break in party loyalty [1, 2].

"His arrogance is responsible for the party’s growing troubles."

This public fallout indicates a struggle for influence within the Trinamool Congress. By targeting Abhishek Banerjee's leadership style, Kalyan Banerjee is voicing a grievance shared by some party veterans who view the rise of the Chief Minister's son as a shift toward dynastic control rather than meritocratic leadership. The refusal to provide legal aid further underscores the severity of the personal and professional breach.
