The British mum killed by a speedboat in Corfu while out swimming desperately waved for help after being struck, say eyewitnesses.

Claire Glatman, 60, died after being hit by the boat’s propeller off Avlaki beach in Corfu on Monday.

Her body was discovered by a swimmer and pulled from the water around 10am before she was pronounced dead at the scene.

The mum-of-four lived in Bedale, North Yorkshire.

She is the wife of multimillionaire property tycoon Mark Glatman and they were on a family holiday with the eldest of their two daughters. The couple also have two sons.

Authorities said they were questioning dozens of swimmers in the area in a bid to identify the owner and driver of the speedboat

It is believed the speedboat was pulling water skiers when it collided with Mrs Glatman and failed to stop after striking her.

Eyewitnesses have told Corfu Press, meanwhile, that the tragic mum was seen waving for help in the seconds after the collision.

Coroner Ioannis Aivatidis said Mrs Glatman suffered injuries to her left wrist, arm, chest, pelvis and upper right leg, leading to internal and external haemorrhaging.

Aivatidis added that she was hit hard by the speedboat but remained alive for a few minutes. He said the wounds were so severe that no attempt to resuscitate her would have worked.

A boat found unoccupied at a beach in the resort of Agios Stefanos has been seized and moved to a marina for a forensic investigation.

Three English nationals, aged between 20 and 30 - two of whom have holiday homes on the island - were questioned by police in Greece on Tuesday.

A coast guard official said: "Enquiries are ongoing. They have not been formally linked to this tragedy."

Local media said Mrs Glatman was “very popular in the local community” and was described by a friend as "a very good and genuinely nice person".

Mrs Glatman is believed to have met her husband on the island 30 years ago and the couple bought a villa recently.

She is believed to have swam in the same spot, around 300 metres from shore, every day and was an experienced swimmer, according to pals.

The UK's Foreign Office said: "We are supporting the family of a British woman following her death in Corfu and our staff are in contact with the Greek police.

"Our thoughts are with her family at this difficult time."
