Underwater Liffey walk completed for charity challenge
A 44-year-old English businessman has successfully completed an underwater walk across the Liffey in Dublin city centre.
Graham Boanas undertook the challenge to raise money for Debra Ireland, a charity which helps people who suffer from the skin blistering disease Epidermolysis Bullosa or EB.
He's now on his way to London to cross the Thames, and will then attempt an underwater walk across the River Humber in the east of England.
