The Delhi Exodus: 20 Rebel TMC MPs Align with BJP to Form Separate Lok Sabha Bloc

The massive rebellion within the Trinamool Congress (TMC) has officially reached New Delhi and has taken a sharp pro-BJP turn. On Tuesday, June 9, 2026, senior TMC leader and Lok Sabha Chief Whip Kalyan Banerjee confirmed that the party's rebel MPs have effectively aligned themselves with the Bharatiya Janata Party (BJP), stating explicitly: "Today their leader is Narendra Modi; they have become BJP."

The crisis escalated dramatically on Monday, June 8, when 20 of the TMC's 29 Lok Sabha MPs held a covert meeting at the New Delhi residence of Union Minister and BJP West Bengal observer Bhupendra Yadav. According to sources close to the development, the 20 rebel parliamentarians have decided to decisively break away from Mamata Banerjee and Abhishek Banerjee's leadership to form a separate bloc in the Lok Sabha. Their explicit goal is to support the BJP-led National Democratic Alliance (NDA) government at the Centre.

Dastidar Emerges as Rebel Faction Leader

Barasat Lok Sabha MP Kakoli Ghosh Dastidar is emerging as the designated leader of this new rebel faction. Despite recently being removed as the Trinamool chief whip, Dastidar reportedly plans to submit an official letter signed by the 20 breakaway MPs to the Lok Sabha Speaker, seeking formal recognition of their standalone bloc.

The Mamata loyalist camp, severely weakened by both the prior state assembly split and now this parliamentary exodus, has launched a fierce verbal counter-offensive. Addressing a press conference in New Delhi on Tuesday, Kalyan Banerjee, alongside MP Kirti Azad, slammed the defectors. He challenged the rebel MPs, stating they were entirely free to leave but urged them to "stop writing TMC leader/MP beside your name." Banerjee specifically targeted Dastidar, accusing her of utilizing state and central security cover to target loyal TMC leaders in her constituency with the active help of the BJP.

Meanwhile, Krishnanagar MP Mahua Moitra took to social media to dare the rebels to resign and face re-election.

"Mandate was NOT for NDA," Moitra posted dynamically. "All the greedy self-serving traitors with yellow-stained pants can please join BJP now — resign your seats & contest on BJP ticket. Let's see what big heroes you are."

Moitra also directly criticized Baharampur MP Yusuf Pathan for allegedly rushing to Delhi at the invitation of Union Home Minister Amit Shah.

The BIGSTORY Reframe — Collapse of the Two-Front Strategy

Mainstream political commentary is treating this as a sudden, isolated factional rift over leadership egos, but the "Missed Angle" here is the absolute synchronization between the TMC's collapse in Kolkata and its structural implosion in Delhi.

Just last week, 58 out of 80 TMC MLAs rebelled in the West Bengal Assembly, electing Ritabrata Banerjee as the Leader of the Opposition. Now, 20 out of 29 MPs are executing the exact same maneuver in the Lok Sabha.

This is not a localized dispute over internal party management; it is a highly coordinated, systemic dismantling of Mamata Banerjee’s entire political infrastructure. By securing the support of West Bengal CM Suvendu Adhikari—who held a subsequent strategic meeting with about 10 rebel MPs at MP Satabdi Roy's residence—the BJP is effectively using the TMC rebels to solidify its grip on Bengal while bolstering its numbers in the Lok Sabha simultaneously. This dual-front execution completely neutralizes the TMC as a viable opposition force within the broader national INDIA bloc.
