New Delhi: Trinamool Congress MP Rukmini Mallick on Thursday resigned from the Rajya Sabha, the fourth TMC MP to do so ever since the Mamata Banerjee-led party was ousted from power in West Bengal.

Mallick met the Rajya Sabha chairman and tendered her resignation.

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

“I convey my sincere gratitude to deputy chairman and all functionaries of Rajya Sabha Secretariat extending all help and cooperation during my tenure as member of Rajya Sabha,” she wrote.

TMC MPs Sukhendu Shekhar Ray, Susmita Dev, and Prakash Chik Baraik resigned from the Upper House earlier.
