Expressing "regret" at Malcolm Speed's unceremonious exit as ICC's CEO, Cricket Australia (CA) said his stepping down has shown that it is "challenging" to administer the "diverse global constituency" of the governing body.
CA Chairman Creagh O'Connor said the manner in which Speed was asked to take a paid leave, after a "fundamental breakdown" in his relationship with the ICC executive board, was regretful.
"As Chairman of Cricket Australia, I note with regret that Malcolm Speed's distinguished career as an international cricket administrator has ended in the manner in which it has," O'Connor said in a statement here.
"I have worked with Malcolm for many years during his time as Chief Executive Officer of the then Australian Cricket Board and, for the last seven years, as Chief Executive of the International Cricket Council," he added.
O'Connor said with cricket becoming a "global sport", it was becoming difficult to administer the sport as several individual interests were also to be managed along with the game's interests.
"As many have noted in the last few days, administering the ICC, which features a diverse global constituency, is a challenging task," he said.
"Cricket is becoming a genuinely global sport and will only have a long-term, sustainable future if the diverse interests within the game can put the game's interests ahead of any other interests," he urged.
O'Connor lavished praise on Speed and said his services would be missed.
"I know first-hand of the dispassionate, professional and diligent manner in which he has sought for cricket to achieve high standards of administrative excellence," he said.
