Indian experts have given the go ahead for the scrapping of a controversial cruise liner which environmentalists say contains toxic material harmful to ship-breakers, officials said on Wednesday. Greenpeace and other groups say the 46,000-tonne Norwegian cruise liner Blue Lady, which anchored in June off the Alang ship-breaking yard in the western state of Gujarat, contains more than 900 tonnes of asbestos which would put the health of workers at risk.
