"He is Vulgar-Nidhi, not Udhayanidhi," TVK on Tuesday stepped up its attack on Tamil Nadu Leader of Opposition Udhayanidhi Stalin over his remarks on actor Trisha. Reacting to the arrest of the DMK leader on Tuesday morning over his derogatory comments on Trisha, TVK leader Americai Narayanan called the DMK leader's speech "vulgar". "What's his name? Vulgar-Nidhi? He should not be called Udhayanidhi. He should change his name to Vulgar-Nidhi," Narayanan said while speaking to NDTV after the arrest.
