Each manager will work with two countries, accompanying teams on tour from 1 June.

Their appointment was one of the main recommendations of Sir Paul Condon's Anti-Corruption report of April 2001.

"These appointments are a powerful demonstration of the ICC's resolve to rid the international game from the threat of match fixing and corruption, which have tarnished cricket's reputation around the world over the past two years," said ICC chief executive Malcolm Speed.

"The highly professional security infrastructure now being put in place will provide the game with a discreet but effective long term deterrent," said Lord Condon.

"The aim is to rid cricket from corruption once and for all, but without sacrificing the enjoyment of players and those who follow the game."

The managers were chosen for their outstanding service in police forces and the military.

They are contracted to the ICC on a full time basis and if both teams assigned to a security manager are playing at the same time one of the other managers will provide cover.

They will attend an induction camp in Sri Lanka for formal training and to provide security for the two venues to be used for the ICC Champions Trophy in Colombo, in September.
