Sushmita Dev resigns as a Rajya Sabha member, handing a resignation letter to Chairman C. P. Radhakrishnan seeking immediate acceptance. Multiple outlets report that Dev cites personal and political reasons for her decision, and in related statements she says the matter is “a very long story” and that, in politics, she does not believe everything needs to be disclosed. Her resignation comes days after another Trinamool Congress (TMC) MP and Rajya Sabha member, Sukhendu Shekhar Ray, resigns both from the party and the upper house, also alleging concerns about corruption, governance, and the handling of the RG Kar hospital rape-murder case.

News coverage frames Dev’s exit as part of broader internal strain within the TMC following recent assembly election losses in West Bengal. It also coincides with reporting of a legislative-wing revolt in West Bengal, including support from some TMC MLAs for a rebel leader for the Leader of the Opposition position rather than the party’s nominee. In this context, Dev is described as a prominent national TMC figure from Assam, who joined the party in 2021 after leaving Congress and was later nominated to the Rajya Sabha.
