The DMK was responsible for ruining Tamil Nadu by revoking prohibition, he said added that DMK government was responsible for power scarcity, which had driven investors to other States.The DMK started the freebies culture in the State and was involved in corruption, besides introducing the ‘Thirumangalam formula’ of bribing voters, Anbumani said and added that plunder of natural resources began during the DMK rule. The verdict on the Mullaiperiyar dam row was delayed due to the wrong approach of the DMK government, Anbumani said and accused the DMK of betraying the State when Katchatheevu was acceded to Sri Lanka. He also alleged that the DMK bowed to the pressure of the Centre and failed to renew the agreement on water sharing in Cauvery dispute. Karnataka built three dams across the Cauvery during the DMK regime, he said and added that the party had failed to put pressure on the Centre to gazette the order of Cauvery Water Disputes Tribunal and form the Cauvery Management Board when it was part of the UPA government. India’s PMK Chief Ministerial candidate Anbumani Ramadoss on Monday lashed out at DMK treasurer MK Stalin, his likely competitor for the job, charging the DMK with betrayal of the Tamil people on Sri Lankan Tamils issue, besides Mullaiperiyar and Cauvery disputes, the New Indian Express reported.Referring to Stalin’s open letter to Chief Minister O Panneerselvam, the PMK youth wing leader in an open letter said the DMK had failed to stop the massacre of innocent Tamils in Sri Lanka and suppressed the protests in Tamil Nadu during the peak of the military offensive. When LTTE leader Velupillai Prabhakaran’s mother came to Chennai for treatment, the DMK government sent her back without allowing to land in the city.
