The CID has reached Mamata Banerjee's residence as part of an investigation into alleged forged signatures used in a communication endorsing Sobhandeb Chattopadhyay as Leader of Opposition. The complaint was raised by TMC MLAs Ritabrata Banerjee and Sandipan Saha, who claimed no such resolution was passed during a party meeting and alleged the document was fabricated. The controversy comes amid a growing rebellion within the Trinamool Congress, further intensifying the party's ongoing political crisis.
