New Delhi, Sept 25 (ANI): Opposition leaders slammed the government over the contentious Nuclear Liability Clause after the Cabinet Committee on Security (CCS) gave its clearance, paving way for signing of an agreement between Nuclear Power Corporation of India Ltd (NPCIL) and America's Westinghouse. India is making a last-minute push to close a nuclear deal in time for a meeting between U.S. President Barack Obama and Prime Minister Manmohan Singh, who has made atomic energy cooperation with Washington a hallmark of his tenure. Under the proposed deal, India would contract Toshiba's U.S. nuclear unit Westinghouse for preliminary works, including information sharing, a senior Indian official said. The aim is to build nuclear plants in the state of Gujarat. The clearance has been criticized by Indian opposition parties, who accused the government of trying to bypass due process and water down the liability law.
