The son of Argentinius, who with Nick Skelton represented Britain at the 2004 Athens Olympics (pictured) and the 2005 European Championships, died today (20 January) at Shaw Farm Stud, home of his long-term owners the Hales family. Nick and Arko won top-class grands prix across the globe, including the world’s richest class, the CN International at Spruce Meadows, and jumped numerous Nations Cup double clears. He won £1.2m before his retirement from the sport in 2008. Nick has always credited Arko as the horse who brought him back into the sport after he broke his neck in a riding accident.
