After Gautam Gambhir sent defamation notice to Arvind Kejriwal, Manish Sisodia, & Atishi seeking an apology, the AAP said they'll too send defamation notice. The notice has been sent because AAP alleged Gambhir is spreading derogatory pamphlets against AAP's Atishi. Sisodia said, "We are being defamed & they are sending a notice. We'll file defamation case against them today." Also, Gambhir said he will resign if proved guilty.
