The Trinamool Congress is facing growing internal unrest after its crushing defeat in the West Bengal Assembly election, with senior leaders openly criticizing the party leadership.Senior MPs have begun targeting party chief Mamata Banerjee, blaming the leadership for the loss that handed power to the BJP. The open dissent marks a rare public rupture in a party long known for tight discipline around Banerjee.The turmoil deepened after the Election Commission froze the original TMC name and symbol, allotting new identities to rival factions. Candidate withdrawals and reversals ahead of the October 6 bypolls added to the chaos, with the Nandigram candidate withdrawing after meeting Suvendu Adhikari.Banerjee intervened directly to reverse a withdrawal in Rejinagar, underlining the pressure on her camp. The rebel Trinamool faction's political position remains uncertain.The unrest could reshape Bengal's opposition landscape as the bypoll results test the BJP's momentum and the surviving strength of Mamata's camp.
