A GROUP of scuba divers will undertake an underwater five-mile relay challenge at Coniston Water in memory of one of their club members.

The Ribble Valley branch of the British Sub-Aqua Club are remembering Duncan Priestley, of Accrington, who passed away, aged 59, in August 2013 from cancer.

Pairs of scuba divers will use a relay system to cover the five-and-a-half-mile lake underwater on Sunday (July 13) from 6am to 4pm and their aim is to raise a boat load of cash for lifeboat charity RNLI.
