International Cricket Council (ICC) chief executive Haroon Lorgat has announced he will step down when his current contract expires at the end of June 2012.
South African Lorgat was offered a three-year extension to his current deal in June this year, but instead decided to sign for just an additional 12 months.
"My sense is to step aside after having delivered a successful ICC Cricket World Cup and the new global ICC strategy which is now in place," Lorgat told the organization's official website.
"In 2010, I felt there was much work for me to complete during 2011 which included protecting the integrity of the game and restoring the reputation and image of the ICC.
"Having dealt decisively with the spot-fixing issues, delivered a highly successful ICC Cricket World Cup and adopted a new global strategy, I feel the time is right to move on."
It has been a difficult year for the ICC, with the sport dominated by the spot-fixing trial which led to Pakistan trio Salman Butt, Mohammad Asif and Mohammad Amir being handed prison terms by a British court.
"Overall I feel personally satisfied with having successfully led the ICC through some difficult issues," the 51-year-old Lorgat said.
"Although disappointed that the Test World Championship will not be played in 2013, I am confident that with the strategic restructures we have undertaken, all three formats can be sustained at international level," he added.
The ICC said it would begin the process of choosing a replacement for Lorgat immediately.
Meanwhile, Australia have unveiled South African Mickey Arthur as their new coach on a deal which will run until after the 2015 World Cup.
The former South Africa coach replaces Tim Nielsen, who resigned following Australia's series win over Sri Lanka in September.
"I am honored and privileged to have another chance to coach an international team, particularly a team of the ilk of Australia," the 43-year-old told Cricket Australia's official website.
"I think I bring a fresh, unblinkered eye to the role after plotting against Australia ... Australia has an abundance of cricket talent and I am confident the talent is there to ensure Australia is successful."
The appointment comes off the back of Australia's dramatic two-wicket defeat of South Africa in the final match of their two-Test series on Monday. The series finished 1-1.
Arthur's first series in charge of Australia will be against New Zealand, with the first Test set to begin in Brisbane on December 1.
He is the first non-Australian to hold the post.
