A man has been rescued while swimming in just his underpants in high seas during Storm Diana.

The incident happened in Mount's Bay, Cornwall in southwest England after someone spotted the man and called the RNLI.

The footage shows the man getting battered by large waves due to 75mph winds.

According to local reports, the man said he "just fancied going for a swim" and he refused help to start with from the coastguard.

A man has been rescued while swimming in just his underpants in high seas from Storm Diana. The incident happened in Mount's Bay after someone spotted the man and called the RNLI. The man at first refused help, but after being battered by the large swells from the Force Ten winds (he can be seen getting covered by waves in the video) the volunteer lifeboat crew eventually persuaded him to get aboard.

Presumably frozen cold as he wasn't wearing a wetsuit, he was given warm blankets and treated at Penzance harbour by a Coastguard first responder.
