CHENNAI, 3 FEB: The DMK today charged the Centre and the AIADMK government with being “lethargic” in solving the Koodankulam nuclear plant row and raised the pitch on the Mullaiperiyar Dam issue demanding that Kerala restore the area, where the reservoir is located, to Tamil Nadu. The DMK general council ~ its top decision-making body ~ met here against the backdrop of the Supreme Court verdict on 2G spectrum scam where the apex court had pointedly blamed former telecom minister Mr A Raja, its senior leader.
