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

The departure represents a significant blow to the leadership of Mamata Banerjee as the party faces a sudden wave of high-profile exits [3].

Dev's resignation from the upper house in New Delhi follows the exit of Sukhendu Sekhar Ray [3]. This makes Dev the second TMC parliamentarian to resign this week [1].

Reports indicate that Dev has stepped down from both her legislative role in the Rajya Sabha and her internal party positions [4]. The loss of two high-profile members within a two-day window has been described as a massive setback for the party [3].

While the resignations have created a void in the TMC's representation in the upper house, the party has not yet provided a public reason for the departures. The timing of these exits suggests internal instability within the party ranks as they navigate the current political landscape in India.

The rapid loss of two senior parliamentarians within 48 hours suggests a potential rift or systemic dissatisfaction within the Trinamool Congress. Because these exits include both a party post and a legislative seat, the party faces an immediate need to fill strategic vacancies in the Rajya Sabha while managing the optics of internal instability.
