Sir Ronnie Flanagan, who has held the role of independent chair of the ICC's Anti-Corruption Unit (ACU) since 2010, will retire at the end of October. His departure follows the decision of ACU chief Alex Marshall, who is set to retire in November.

Flanagan, a distinguished senior police officer, previously served as chief inspector of constabulary for England, Wales, and Northern Ireland, and as chief constable of the Northern Ireland police service. He succeeded Lord Paul Condon, who stepped down in 2010 after a decade as the ACU's inaugural head.

Condon was appointed by the ICC in 2000 to address the rising threat of match-fixing, which led to lifetime bans for international captains Mohammad Azharuddin, Saleem Malik, and Hansie Cronje. His efforts were crucial in establishing anti-corruption frameworks to protect the integrity of the sport.

Before his departure, Condon had warned that T20 cricket, particularly domestic franchise leagues, posed a significant risk to the game's integrity. His concerns were validated when the IPL corruption scandal surfaced in 2013. Shortly after, Flanagan urged cricket boards to strengthen anti-corruption laws to penalize players, officials, and franchise owners involved in corrupt practices, especially in domestic T20 leagues.

On Monday, the ICC announced that they plan to recommend a successor for the ACU chair by their October quarterly meetings.
