Sushmita Dev, a Rajya Sabha MP for the Trinamool Congress, has resigned from all party posts and her seat in the upper house [1].

This departure signals a deepening internal crisis for the Trinamool Congress as it faces a wave of high-profile dissent. The loss of experienced legislators in the Rajya Sabha weakens the party's presence in New Delhi and suggests growing instability within the organization's leadership structure.

Dev's exit is the second such resignation from the party within a week [1]. This follows the recent departure of Sukhendu Sekhar Ray, another prominent figure within the party [2]. The timing of these exits suggests a pattern of attrition that is putting pressure on the leadership of Mamata Banerjee.

Reports indicate that Dev's decision comes amid a climate of growing internal friction. While the party has not officially detailed the cause of the rift, observers said that the resignations are part of a broader trend of rebellion [3]. There is currently speculation that Dev may join the Bharatiya Janata Party, though this has not been formally confirmed [1].

Dev's resignation occurred three days into the week [4]. The loss of two upper-house members in such a short timeframe creates a vacuum in the party's legislative strategy, and it raises questions about the loyalty of other party members.

As the Trinamool Congress manages these exits, the focus remains on whether more members will follow Dev and Ray into the rebel camp [3]. The party must now navigate the political fallout of these resignations while attempting to maintain its stability in the face of potential defections to rival parties.

“Sushmita Dev has resigned from all party posts and her seat in the upper house.”

The rapid succession of resignations by Rajya Sabha members suggests a systemic failure in the Trinamool Congress's internal dispute resolution. When senior legislators exit in clusters, it often indicates a lack of confidence in the current leadership or a strategic shift by members toward opposition parties like the BJP to preserve their political viability.
