Experts state in a leaked pre-trial report that the cruise giant failed to act in 'Costa Concordia' accident.

Europe’s biggest cruise operator Costa Crociere may have failed to act promptly in the Costa Concordia disaster, according to a pre-trial report that still heaped much of the blame on the ship’s captain.

The report, which was leaked in the Italian press on Thursday, was commissioned by the judge investigating the tragedy which claimed 32 lives when the giant ship with 4,229 people on board hit rocks on January 13, 2012, reports the 'South China Morning Post' via Agence France-Presse in Rome.

Nine people are under investigation for the shipwreck off the island of Giglio, including captain Francesco Schettino and three Costa executives.
