Canada whale boat tragedy: Britons named

All five of the British people killed during a whale watching trip in Canada on Sunday have been named.

Among them were a father and son who'd been on holiday on Vancouver island.

The Leviathan II sank so quickly off the coast of western Canada that there was no opportunity to send a Mayday call, its operator has said.

An investigation is underway into why the boat sank so suddenly.

James Cook reports.
