The Trinamool Congress is facing internal instability and reports of a potential split following a heavy electoral defeat in West Bengal [1].

This political shift marks a major transition of power in the state, as the party led by Mamata Banerjee loses its long-standing dominance to the Bharatiya Janata Party (BJP).

According to election data, the BJP is nearing 200 seats in the West Bengal Assembly [4], while the Trinamool Congress has been reduced to double-digit seats [4]. In the wake of these results, Suvendu Adhikari took the oath as the new Chief Minister. "We will rebuild Bengal," Adhikari said [3].

Despite the loss, Mamata Banerjee (TMC) initially resisted stepping down. "I will not resign," Banerjee said [1]. However, the defeat has triggered power struggles within her party. Two TMC legislators were expelled from the party [1], and reports surfaced of these expelled members meeting other MLAs at the Kolkata MLA hostel to form a new faction [1].

While some reports suggest the party is on the brink of a collapse, others indicate the TMC remains united and is attempting to regroup under Banerjee's leadership [1]. The volatility extends beyond political meetings, with reports of violence following the announcement of the results.

"Arson and vandalism have been reported at TMC offices across the state," a senior TMC official said [2].

The tension in Kolkata reflects a broader struggle for the future of the party as it navigates its smallest legislative presence in years.

"I will not resign," Mamata Banerjee said.

The dramatic swing in seat counts and the subsequent internal friction within the TMC suggest a fundamental realignment of West Bengal's political landscape. The attempt by expelled legislators to form a new faction indicates that the party's centralized leadership under Mamata Banerjee is facing its first significant challenge from within, potentially permanently fracturing the party's base.
