Dunmore

The Irish Coast Guard said the missing man is believed to have gone overboard from a UK registered yacht 16 nautical miles south of Dunmore East in the Irish Sea.

The search on Sunday will continue with the help of a helicopter from Waterford and a Dunmore lifeboat.

Reece Williams, 23, Lewis Soden, 24, and Connor Page, 21, died when the car they were travelling in crashed near Dunmore at about 18:15 on Friday.

Matthew Hollis, from Northampton, will set out from Ness Point in Suffolk on Wednesday, aiming for Dunmore Head in County Kerry with a compass as a guide.

"The biggest challenge with this attempt is that I've got a ferry crossing, so I've got to try to get to the port without navigating, and - I've deliberately not done a lot of research, but I think Dunmore Head is fairly non-descript in Ireland - it's not like Land's End - so I may not even realise I'm there."
