International Cricket Council boss David Richardson has mounted a fierce defence of the organisation's anti-corruption unit.
The ICC is to begin a review into its safeguards despite the existence of the established anti-corruption and security unit (ACSU).
But chief executive Richardson insists any suggestion the ACSU is failing is wide of the mark.
"The ICC ACSU remains a world leader in the fight against corruption in sport, and has done some outstanding work since its inception in 2000," he said.
"The suggestion that the ACSU might be failing in its duty to protect the game is entirely misplaced and inaccurate.
"The cricket landscape and the risk of corruption is changing rapidly in recent years due to the increasing number of domestic Twenty20 cricket leagues, as well as the incorporation of domestic anti-corruption units by a number of member boards.
"The ICC board considered it to be an appropriate time to carry out a review into the overall structure established to fight against the threat of corruption at all levels of the sport.
"However, it is important to emphasise that the review is only commencing - and therefore to draw any conclusions on the outcome of the review will be premature and detrimental to the working of such an important unit.
"We are committed to putting in place the very best structures and personnel to protect the game, and there is nothing unusual about the commission of an internal review."
