Sushmita Dev, a Rajya Sabha MP for the Trinamool Congress (TMC), resigned from all party posts and her parliamentary seat on Wednesday [1].

This departure marks a continuing trend of instability within the TMC's upper house representation. Dev is the second Rajya Sabha MP from the party to resign this week [2], signaling a potential rift in the party's leadership or strategic direction.

In a resignation letter addressed to Rajya Sabha Chairman C.P. Radhakrishnan in New Delhi, Dev requested that her departure be processed immediately [3]. "I do hereby resign from the membership of Rajya Sabha, which may please be accepted with immediate effect," Dev said [3].

While Dev's formal letter focused on the administrative act of resigning, party insiders have pointed to ideological or strategic disagreements as the primary driver. An unnamed TMC source said that Dev was unsure about the party's future [2].

The timing of the exit is notable, as it occurred on the third day of the week [1]. The loss of a seat in the Rajya Sabha reduces the party's voting strength in the upper house, where legislative stability is critical for passing national policy.

Dev's exit follows a pattern of high-profile departures from the TMC. The party now faces the challenge of filling the vacancy while addressing the internal concerns that led to the exit of two members within a seven-day window [2].

“"I do hereby resign from the membership of Rajya Sabha, which may please be accepted with immediate effect."”

The resignation of Sushmita Dev, particularly following another MP's exit in the same week, suggests a period of volatility for the Trinamool Congress. When lawmakers cite uncertainty about a party's future, it often indicates a lack of confidence in the current leadership's roadmap or a misalignment with the party's evolving political trajectory.
