New Delhi: Trinamool Congress MP Sushmita Dev Wednesday resigned from the party and the Rajya Sabha, dealing a fresh blow to the Mamata Banerjee-led party which is facing an internal storm after its defeat in the West Bengal Assembly polls.
Dev’s resignation as MP has been accepted by Rajya Sabha Chairman C P Radhakrishnan.
“Sushmita Dev, an elected member of the Council of States (Rajya Sabha), representing the state of West Bengal, resigned her seat in the Rajya Sabha and her resignation has been accepted by the Chairman, Rajya Sabha, with effect from June 10, 2026,” a notification from the Rajya Sabha Secretariat said.
Sources said Dev, who earlier quit the Congress 2021 to join the TMC, is likely to join the BJP as she met Assam Chief Minister Himanta Biswa Sarma after tendering her resignation.
While she declined to comment on TMC chief Mamata Banerjee or her future political plans, Dev said, “It’s my individual decision, what kind of politics I want to do and who should be my leader. I have my reasons and that’s why I have taken my decision”.
On reports of her joining the BJP, she said, “When I take a decision I will let you know.”
Dev said she had resigned due to personal and political reasons and that “everyone has the right to change their mind, and to decide what kind of politics they want to do.”

Daughter of former Union minister and Congress leader Santosh Mohan Dev, she had earlier served as Lok Sabha MP from Silchar in Assam. She was also the former president of the All India Mahila Congress.
Earlier in the day, Dev met the Rajya Sabha chairman and handed over her resignation letter to him.
“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,” Dev said in the letter to the Chairman.
Dev is the second Trinamool Congress MP from the Rajya Sabha to resign this week. Another TMC leader Sukhendu Sekhar Ray resigned from the party and his membership from the Council of States.
Sources said several party MPs are also deciding to form a separate group and align with the ruling NDA like the seven AAP MPs who had resigned from the Aam Aadmi Party (AAP) and later joined the BJP.
A majority of Trinamool’s 80 MLAs have already formed a separate group led by Ritabrata Banerjee as the leader of opposition in the state Assembly.
