Ms. Dev, a former Congress leader who had joined the TMC a few years ago, met Rajya Sabha chairman C.P. Radhakrishnan and resigned from the membership of the House.

She is the second MP of the TMC to resign this week. Earlier, Sukhendu Sekhar Ray had tendered his resignation from the party as well as the Rajya Sabha.

Sources said Ms. Dev is likely to quit the TMC and join the BJP. She has also met Assam Chief Minister Himanta Biswa Sarma.

In her resignation letter, she said, “I do hereby resign from the membership of Rajya Sabha, which may please be accepted with immediate effect.”

“I convey my sincere gratitude to your excellency, hon’ble Deputy Chairman and all functionaries of the Rajya Sabha secretariat extending all help and cooperation during my tenure as a member of the Rajya Sabha,” Ms. Dev said in the letter to the Chairman.

The Trinamool Congress is facing a rebellion after its defeat in the West Bengal Assembly polls, with several party MPs deciding to form a separate group and align with the ruling NDA.

A majority of Trinamool’s 80 MLAs have already formed a separate group led by Ritabrata Banerjee as the Leader of the Opposition in the State Assembly.

All India Trinamool Congress (AITC) leaders Kalyan Banerjee, Chief Whip of AITC in Lok Sabha, and Lok Sabha MP Kirti Azad addressed a press conference in New Delhi on Tuesday (June 9, 2026) regarding the ongoing rebellion in the party.

Several MPs from the Trinamool Congress (TMC) met with Union Minister and Bharatiya Janata Party (BJP) West Bengal observer Bhupendra Yadav at his residence on Monday (June 8, 2026). Citing the meeting, Mr. Banerjee accused the leaders of siding with the BJP and said, “Today their leader is Narendra Modi. They have become BJP.”

Mr. Banerjee said the leaders were free to leave the party but urged them to “stop writing TMC leader/MP beside your name”.

“Post the election results, did these leaders or Sharmila Sarkar stand by the families of the deceased or affected party workers?” asked the TMC leader.

The 20 rebel MPs plan to form a separate bloc and support the BJP-led National Democratic Alliance (NDA) government at the Centre. Barasat Lok Sabha MP Kakoli Ghosh Dastidar is emerging as the leader of the bloc.

Mr. Banerjee has said that Ms. Dastidar has been targetting the TMC leaders with the help of the BJP.

“Kakoli Ghosh immediately took security from the State and Central government, and now she is, with the help of the BJP, targeting leaders from TMC of her area,” said the TMC MP.

Meanwhile, Trinamool Congress leader Sabyasachi Dutta was arrested early on Tuesday (June 9, 2026) from West Bengal’s North 24 Parganas district on charges of extortion and criminal intimidation, police said.

Senior Trinamool Congress MP Sukhendu Sekhar Roy on Monday (June 8, 2026) said that he has resigned from the Rajya Sabha and from the party.

Mr. Roy has been one of the dissenting voices in the Trinamool Congress and had distanced himself from the party after the debacle in the 2026 assembly polls in the State. The 77-year-old Trinamool leader raised several issues like corruption in the party and said there was no introspection in the party after the loss.

The resignation of Mr. Roy brings to the fore differences in the Trinamool Congress MPs. Speculations are rife that more MPs may quit the Trinamool Congress. A newly elected party Rajya Sabha MP may also quit the party.

The party is also facing a rebellion in its legislature party, with about 60 MLAs electing a new Leader of Opposition.

“The legislatures also probably did not have the confidence that the party was running in the right direction. There was no forum within the party to discuss the political issues and other social issues,” he told media persons in Delhi.

After the rape and murder of a doctor at Kolkata’s R G Kar Hospital, Mr. Roy had criticised the party. “I was side-lined in the party for long, had participated in protests against the crime,” he said.

A former Congress leader who was close to the former President Late Pranab Mukherjee, Mr. Roy had served in the Rajya Sabha since 2011, and also remained the chief whip till 2024 and deputy leader till 2019 .
