OUR SPECIAL GUEST

THE extraordinary achievements of Sir Ranulph Fiennes, right, make him the world’s greatest living explorer. He served in the Army for eight years, as a member of the Royal Scots Greys and the SAS, and later embarked on missions to many of Earth’s most inhospitable places. He was the first person (with Charles Burton) to conquer both North and South

Poles on foot, and was the first (with Mike Stroud) to cross the Antarctic continent on foot. In 2009, he climbed Everest at 65, becoming the oldest Briton to reach the summit.
