CHENNAI:The PMK Chief Ministerial candidate Anbumani Ramadoss on Wednesday said the prohibition protests became a mass movement due to the agitations by his party. His claim challenged DMK treasurer MK Stalin’s claim that M Karunanidhi’s promise of prohibition triggered anti-liquor protests in the State. The widespread protests only forced a change in Karunanidhi’s mind, Anbumani said in an open letter to Stalin and reiterated that the cultural deterioration in the State was the DMK government lifted the prohibition. Everyone doubted if the DMK leader had changed his heart for people’s welfare or because he had an eye on the approaching Assembly elections, he said. He reiterated the charge of his father and PMK leader S Ramadoss that Karunanidhi had promised five times to usher in prohibition but failed to fulfill his promises. “If the DMK leader’s promise is made keeping the people’s welfare at heart, will the DMK prove it by closing the distilleries owned by his partymen?”, Anbumani asked.
