Andrew Jennings, an investigative journalist who exposed major corruption in FIFA and the International Olympic Committee, has passed away.

He was 78.

Jennings’ Twitter account said on Monday said the journalist passed away on Saturday “after a brief, sudden illness.”

He passed away in a hospital in Carlisle, England. The cause of his death was an aortic aneurysm, said his partner and frequent co-author, Clare Sambrook, according to The Washington Post.

Jennings authored books and stories that unveiled

Those books included “Lords of the Rings: Power, Money and Drugs in the Modern Olympics” (1992) and “Foul! The Secret World of FIFA: Bribes, Vote-Rigging and Ticket Scandals” (2005) that unveiled the secrecy and scandals that plagued the Olympics and soccer, respectively, for years, if not decades.

“If you had to put only one name to the revolution of the international sports debate over the past 30 years … that name and that person would be Andrew Jennings,” wrote Jens Sejer Andersen, director of Play The Game, an organization that promotes ethics in sport.

His reporting also led to the demise of former FIFA president Sepp Blatter.
