The Upper House Collapse: 3 Rajya Sabha MPs Quit in 4 Days as Trinamool Implosion Widens

The massive structural implosion tearing through the Trinamool Congress has rapidly accelerated into the Upper House of Parliament. In a devastating blow to Mamata Banerjee's high command, three Rajya Sabha MPs have resigned within a tight four-day window, fracturing the party's national footprint amid an unprecedented multi-front political rebellion.

The latest blow fell when North Bengal leader Prakash Chik Baraik officially submitted his resignation to Vice President and Rajya Sabha Chairman C.P. Radhakrishnan, stepping down from the chamber with immediate effect. Baraik's departure follows the high-profile exits of Assam leader Sushmita Dev and party veteran Sukhendu Sekhar Ray earlier this week. Collectively, these swift exits have triggered a steep slide in the TMC's Rajya Sabha strength, dropping their presence down from 13 to just 10 members.

A Coordinated Chain of Defections

Justifying his departure to reporters, Baraik did not mince words, turning his resignation into an indictment of the party's fading electoral viability. He acknowledged that the political winds in West Bengal have decisively shifted.

"The mandate in West Bengal was not in favour of the Trinamool Congress," Baraik stated flatly. "The Trinamool Congress did not win a single seat in my constituency. The mandate is in favour of the BJP... I thought I should resign."

This latest exit completes a striking, highly coordinated chain of defections that began at the start of the week:

• Sukhendu Sekhar Ray: The dominoes began falling on Monday when veteran leader Sukhendu Sekhar Ray resigned while launching a scathing attack on his own party. Ray cited "widespread unbridled corruption" and severe state-level law and order failures, declaring that the people of Bengal have voted to bring a definitive end to the TMC's "15-year anarchical rule."
• Sushmita Dev: On Wednesday, June 10, the party's prominent face in Assam, Sushmita Dev, resigned from both her Rajya Sabha seat and the primary membership of the party. Stating she refused to ride in "two boats," Dev immediately triggered intense political speculation by holding a strategic huddle in New Delhi with Assam Chief Minister and senior BJP strategist Himanta Biswa Sarma.

The BIGSTORY Reframe — The Three-Front Annihilation

Mainstream analysis will likely classify these developments as scattered, individual cases of career opportunism or post-election fatigue. However, the "Missed Angle" here is the sheer velocity and perfect synchronization of the TMC's collapse across all three distinct legislative domains simultaneously.

The high command in Kalighat is not facing a routine internal factional dispute; it is witnessing a highly organized, three-front annihilation of its entire political infrastructure.

Consider the scale of the collapse inside a single week: in the West Bengal State Assembly, 64 out of 80 TMC MLAs have effectively mutinied to elect Ritabrata Banerjee as their independent leader. Simultaneously, in the Lok Sabha, a crushing majority of 20 out of 29 MPs are actively carving out a breakaway, pro-NDA bloc under Kakoli Ghosh Dastidar.

The immediate unraveling of the Rajya Sabha contingent provides the final piece of the puzzle. It confirms that Mamata Banerjee's centralized command-and-control architecture has suffered a fatal system failure. In a matter of days, the structural breakdown has transformed the TMC from a formidable, fortress-like regional ruling power into a deeply fractured, hyper-isolated entity fighting for its survival on both the state and national stage.
