Celtic today began their search for a new chief executive after the club's plc board announced Ian McLeod would leave Parkhead by the end of the month.
McLeod is to step down when his contract expires on April 29th and has already been linked with a switch to Leeds, who are looking for a successor to Peter Ridsdale.
He had also been embroiled in a spat with the Bank of Scotland Premier League this month over the timing of the final Old Firm fixture of the season.
Celtic chairman Brian Quinn said McLeod's departure had been an amicable one. "Ian has made a significant contribution to the club over the past two years and the board is grateful for his work during what have been challenging times," he said.
"The search for a new chief executive is under way. Celtic, especially after the UEFA Cup run this season, is a major UK and global football club and we will be looking for a suitable candidate to continue the club's growth both on and off the park".
McLeod said: "I have been in discussion with the board in recent weeks and after careful consideration we have agreed that I will leave Celtic when my contract lapses at the end of April.
"It has been a privilege to be part of this club over such a successful period and I would like to take this opportunity to thank all my colleagues who work incredibly hard both on and off the field for Celtic and for the support that they have given me.
"I wish Celtic every success in the future, particularly Martin O'Neill and the team as they continue their committed challenge for the SPL championship and a place in the UEFA Cup final".
