The journalist Andrew Jennings, who has died aged 78 of an aortic aneurysm, did more than any other to expose systemic corruption within the organisations running world sport. In the process he helped to ensure that the International Olympic Committee underwent reform and to bring down the bosses of the football governing body Fifa.
This he achieved through applying what he had learned from investigating crime and police corruption as a press and broadcasting reporter. For Andrew journalism was not a job – it was a mission. In 2000 the New York Times described him as “usually outraged and frequently outrageous”.
