In a fresh setback for the Trinamool Congress (TMC), Rajya Sabha MP Prakash Chik Baraik resigned from the Upper House on Thursday, further deepening the crisis within the party.

Baraik's exit comes close on the heels of the resignations of senior leaders Sukhendu Sekhar Roy and Sushmita Dev, taking the number of TMC Rajya Sabha MPs to quit in recent days to three.

The latest resignation is likely to intensify concerns over growing discontent within the party ranks.

With Baraik stepping down, TMC's strength in the Rajya Sabha is set to decline to 10 MPs.

Sources indicated that the number could shrink further, with as many as three more TMC Rajya Sabha MPs reportedly considering resignation within the next week.

The development marks yet another blow for TMC supremo and former West Bengal Chief Minister Mamata Banerjee, who is already grappling with an unprecedented wave of dissent from within the party.

Political observers believe that further resignations could significantly weaken the party's influence in Parliament and raise fresh questions about its organisational stability ahead of key political battles.

Baraik is expected to meet the Rajya Sabha Chairman shortly to formally submit his resignation. The reasons behind his decision are yet to be officially disclosed.
