Spain's Supreme Court said Tuesday it had found the captain of the Prestige tanker, the British ship insurer and its owner liable for a devastating 2002 oil spill, one of Europe's worst environmental disasters.

Reversing an earlier court decision acquitting the captain Apostolos Mangouras, it sentenced him to two years in prison and also found insurance company The London P&I Club liable for the disaster, as well as ship owner Mare Shipping Inc, it said in a statement.
