Trinamool Congress MP Kalyan Banerjee said on June 11, 2026 [1], that senior leader Abhishek Banerjee has destroyed the party.

This public rift signals a deepening crisis within the Trinamool Congress, as senior members openly challenge the influence of Abhishek Banerjee, often referred to as "Bhaipo," over the party's direction and leadership.

Speaking from Kolkata, Banerjee said the party's recent electoral setbacks and internal instability are due to the actions of Abhishek Banerjee [1]. He said the senior leader has maintained an "arrogant attitude" that has humiliated other veteran members of the organization [1].

Banerjee issued a direct ultimatum to party supremo Mamata Banerjee, also known as "Didi," telling her she must choose between him and Abhishek [1]. He said, "He has destroyed the party" [1].

The accusations come amid a broader pattern of internal volatility. Earlier this month, on May 28, 2026 [2], MP Kakoli Ghosh Dastidar wrote to Lok Sabha Speaker Om Birla to report misconduct by Kalyan Banerjee [2]. Dastidar said Banerjee verbally abused her and used misogyny, stating, "He verbally abused me inside the Lok Sabha" [3].

While Kalyan Banerjee has focused his current criticisms on the leadership of Abhishek Banerjee, other party members have pointed to Kalyan's own behavior as a source of friction. Banerjee said some individuals within the party are "acting with a motive" [4].

The public nature of these disputes suggests a breakdown in the party's internal dispute-resolution mechanisms. With senior MPs trading accusations of abuse and incompetence, the party faces a challenge in maintaining a unified front against political opponents in West Bengal.

“"He has destroyed the party."”

The conflict highlights a power struggle between the established guard of the Trinamool Congress and the rising influence of Abhishek Banerjee. By forcing Mamata Banerjee to choose between senior loyalists and her nephew, Kalyan Banerjee is testing the limits of the party's centralized leadership structure during a period of electoral vulnerability.
