New Delhi: Deputy Chief Minister Manish Sisodia on Friday said Aam Aadmi Party (AAP) will file a defamation case against former cricketer and BJP candidate from East Delhi constituency Gautam Gambhir for allegedly circulating pamphlets with derogatory and casteist remarks against AAP leader Atishi Marlena.

This comes a day after Gambhir sent a defamation notice to Atishi, Sisodia and Chief Minister Arvind Kejriwal, demanding an unconditional apology over the "defamatory" comments against him.
