Actor Nagarjuna Akkineni has filed a defamation suit against Telangana minister Konda Surekha for commenting on the divorce of his son Naga Chaitanya and Samantha Ruth Prabhu. "She has apparently apologised to Samantha. What about my family?" Nagarjuna said. "This is no longer personal...You can't use our names for political gains," the actor further said.
