Chief Minister Suvendu Adhikari has announced that elections to the Kolkata Municipal Corporation (KMC) will be conducted by December 7, 2026, paving the way for the formation of a newly elected civic board in Kolkata.

The ongoing political turmoil within West Bengal’s ruling Trinamool Congress (TMC) has intensified into a full-blown constitutional and legal battle. Following a major internal split, rebel leader Ritabrata Banerjee declared that his faction is prepared to approach the Election Commission of India (ECI) to stake an official claim to the party’s identity and symbol.

The internal fissures ripping through the Trinamool Congress (TMC) exploded into a full-scale parliamentary crisis on Sunday, June 14, 2026, as a powerful dissident faction formalized a strategy to break away from the party’s central high command. The rebel camp, marshaled by several disgruntled senior lawmakers, has officially scheduled a high-stakes meeting with Lok Sabha Speaker Om Birla for Monday morning to demand formal recognition as a separate parliamentary group. Claiming the allegiance of a “substantial number” of sitting TMC MPs, the faction aims to bypass the rigorous penal disqualifications of the Tenth Schedule (Anti-Defection Law) by proving they hold a definitive two-thirds legislative majority of the party’s elected lower-house strength. In Kolkata, the core leadership under West Bengal Chief Minister Mamata Banerjee moved swiftly to contain the damage, fiercely condemning the mutiny as a treasonous conspiracy orchestrated to erode the regional party’s formidable clout in New Delhi. While the TMC high command prepares a slate of immediate suspension notices and legal counters, the outcome of Monday’s memorandum submission remains heavily dependent on the Speaker’s structural ruling, a decision that could radically alter national opposition alignments and shift the power balance within West Bengal’s hyper-polarized political ecosystem.

Following a historic electoral rout, the Trinamool Congress is facing an unprecedented internal collapse. With 60 state MLAs and 20 Lok Sabha MPs forming breakaway factions that bypass anti-defection laws, the battle has shifted to the courts and the Election Commission, where the very survival of the TMC name and symbol hangs in the balance.

The Trinamool Congress suffered another massive blow as Rajya Sabha MP Sushmita Dev resigned from the party and Parliament. Citing the impracticality of pursuing Assam politics under a reeling TMC banner, her sudden exit coincides with a wider rebellion of 20 Lok Sabha MPs and 64 state MLAs.

The West Bengal Criminal Investigation Department (CID) has intensified its probe into the alleged signature forgery case by conducting searches at locations linked to Trinamool Congress leaders Mamata Banerjee and Abhishek Banerjee. The investigation revolves around allegations that signatures of several Trinamool Congress MLAs were forged on a letter submitted to the West Bengal Assembly regarding the nomination of a Leader of the Opposition.
