Four bodies have now been found in the search for missing passengers on a sunken luxury yacht in Sicily.

The head of Sicily’s civil protection agency Salvatore Cocina confirmed the two bodies had been found in the yacht which sank at around 5am on Monday.

The identities of the bodies is unknown at this stage and the search for the remaining two continues.

Among the missing is tech tycoon Mike Lynch and his 18-year-old daughter, who was set to go to the University of Oxford after receiving her A-Level results just last week.

A police boat and divers were also seen entering the water this afternoon.

A helicopter had been drafted in to help the search effort, as divers from the local fire service were seen entering the water with torches attached to their headgear.

Fire crews from the Vigili del Fuoco said they have been accessing the vessel through natural entrances, without making openings.

Remotely controlled underwater vehicles were being used, with naval units and cave divers also taking part in the search, the Italian Coastguard has said.
