Five years ago the popular television and radio broadcaster was diagnosed with diabetes and in April of this year he was admitted to the West Wales General Hospital in Carmarthen where he first had to have two toes, and then later his right leg amputated after contracting a diabetes-related infection.

He stayed in hospital for several weeks but just weeks after leaving he made his first public appearance at the Urdd National Eisteddfod in Carmarthenshire.

Ray travelled around the country giving talks on diabetes and organised a number of events in aid of Diabetes UK Cymru in recent months including a golf tournament at Machynys Peninsula.

Capped 23 times by Wales, he was a member of the Grand Slam and Triple Crown-winning Welsh teams of the late 1970s and early 1980s and the 1980 Lions. Known as a powerful centre, Gravell played for Llanelli RFC between 1969 and 1985 and captained the side from 1980 to 1982. He was also part of the Scarlets team that beat the All Blacks in 1972.
