A great white shark has crossed parts of the Atlantic and could be heading for the UK.

The 4.4 metre shark, named Lydia, is thought to be around 1,000 miles off the coasts of County Cork and Cornwall.

Marine biologist Dr Gregory Skomal, who has been following Lydia's progress, said they were "surprised" at the shark's behaviour.

He told BBC Radio 5 live's Up All Night: "White sharks may well have been crossing the Atlantic forever, but this is the first time we're actually able to observe it."
