Another Blow To TMC: Sushmita Dev Quits Party, Resigns From Rajya Sabha As MP Revolt Deepens

Last Updated:June 10, 2026, 11:23 IST

The Trinamool Congress suffered another political setback on Wednesday after Rajya Sabha MP Sushmita Dev quit party and resigned from the Upper House. She is the second MP to resign in a week after Sukhendu Shekhar Ray.

Dev will meet Vice President and Rajya Sabha Chairman C P Radhakrishnan and submitted her resignation today at 1 pm.

Her exit comes amid growing unrest within the party and days after a large group of Trinamool MPs reportedly extended support to the National Democratic Alliance (NDA).

Rebel faction claims support of 20 MPs

The latest development follows claims made by rebel TMC MP Kakoli Ghosh Dastidar, who on Monday said that nearly 20 party MPs had sought to align with the NDA.

According to Dastidar, a letter regarding the move was submitted to Lok Sabha Speaker Om Birla.

Dastidar is leading the breakaway faction and has been appointed its chief whip. Senior MP Satabdi Roy has been named deputy leader of the dissident group.

The rebel camp’s claims have intensified speculation about the scale of the crisis within the Trinamool Congress.

Turbulence in Delhi

The political uncertainty has also been reflected in developments in New Delhi.

Amid the ongoing turmoil, Trinamool Congress MP Partha Bhowmick on Tuesday formally shifted out of the government bungalow that had been functioning as the party’s operational base in the national capital.

According to sources, Bhowmick himself had requested to be moved from the accommodation.

The move added to signs of growing organisational disruption within the party as tensions between the leadership and rebel MPs continue to escalate.

TMC leadership hits back

The Trinamool Congress leadership has responded sharply to the rebellion.

Addressing a press conference on Tuesday, senior party leader Kalyan Banerjee criticised the conduct of the dissident group led by Kakoli Ghosh Dastidar.

Banerjee said leaders who were unhappy with the party should resign rather than continue to hold positions while publicly opposing the organisation.

He argued that if any leader no longer wished to remain associated with the Trinamool Congress or had serious differences with the party, the ethical course of action was to step down.

The remarks came a day after the rebel camp claimed that at least 20 of the party’s 28 Lok Sabha MPs had decided to support the NDA.

With Sushmita Dev’s resignation, the crisis within the Trinamool Congress appears to have deepened further, adding to the challenges facing the Mamata Banerjee-led party as dissent continues to emerge from within its parliamentary ranks.
