Rebel TMC MP Kakoli Ghosh Dastidar has written a letter to Lok Sabha Speaker Om Birla, seeking expulsion of TMC MP Kalyan Banerjee "for repeated verbal abuse" and "misogynistic comments" within Lok Sabha precincts. Kakoli accused him of using "objectionable, disrespectful and inappropriate" language against her and "other women members" in the Lok Sabha. Kalyan is Mamata Banerjee's close aide.
