Four people and representatives of the Shipping Corporation of Polynesia are due to appear in the Tonga Supreme Court today for arraignment on charges over the sinking of the Princess Ashika ferry, 13 months ago.

Those facing charges of manslaughter by negligence are the former managing director of the Shipping Corporation of Polynesia, John Jonesse, the captain Makahokovalu Tuputupu and his first mate, Semisi Pomale, the acting director of Marine, Viliami Tu'ipulotu and the corporation itself.
