UK Athletics (UKA) chief executive Niels de Vos will step down at the end of this month after 11 years in the role.
Nigel Holl, UKA’s strategy and partnerships director, will take up the position on an interim basis until a permanent successor is found.
De Vos, who previously served as chief executive of Premiership Rugby’s Sale Sharks, is relinquishing the role to pursue ambitions to set up his own business.
The 51-year-old has led a highly successful period for UKA, overseeing the delivery of the IAAF World Championships and World Para Athletics Championships, while he also helped establish the Anniversary Games in London and this year’s inaugural Athletics World Cup.
Team GB has also experienced an upturn in its performance in athletics during De Vos’ tenure, most famously at the 2012 Olympic Games in London.
"Niels has been a fantastic servant to not only UKA, but the sport of athletics as a whole,” said UKA chairman Richard Bower. “The sport has grown and been hugely successful under his leadership.
“UK Athletics will retain his services in a limited capacity in order that a number of important issues where he has led discussions and negotiations are brought to a conclusion.
“We look to the future with confidence that UK Athletics as an organisation and the sport of athletics in the UK are both in great shape and will begin the search for a new chief executive shortly."
