DUBAI - The head of worldwide cricket's anti-fraud body has admitted that corruption will never be totally driven out of the game, in an interview published on Wednesday.

Sir Ronnie Flanagan, the International Cricket Council's anti-corruption chief, however added that fans should be reassured that administrators are doing "everything humanly possible" to stop illegal practices such as match-fixing.

"I'll give you the honest answer that we will never totally, utterly and absolutely eradicate corruption from the game," Flanagan told "But we can make the game a very difficult environment for those who would seek to bring corruption to bear."

Flanagan, who has been at the ICC since 2010, called those who tried to corrupt the game as "most evil". "These are organised criminals. These are members of organised criminal gangs across the world."

Cricket's reputation has been in the spotlight in recent times, most notably with the jailing of three Pakistan internationals for spot-fixing during the 2010 Test Series in England. All three – M Aamir, Salman Butt and M Asif -- have now been released and are now resuming their cricket careers.

Asked if any should be picked for international duty by Pakistan again, Flanagan said that was a matter for the Pakistan Cricket Board (PCB). "They've been punished, they've met their punishment," he said. "It's now a matter, I think, for their home board to decide whether they should ever grace an international cricket team again." He added: "That's not just a question of ability, that's a question of their remorse, their realisation of how wrong their behaviour was."

Of the three, the young star bowler Amir, 23, is most likely to represent his country again though he was omitted from the squad recently selected to play England in the upcoming Test Series in the UAE next month.

Cricket's integrity remains under constant threat. Last week, Chris Eaton, the executive director of the Qatar-based International Centre for Sport Security, said that after football, cricket is the main sport worldwide for illegal gambling. One estimate by an expert this year calculated that the sports betting market is worth $3-trillion annually, the vast majority of that illegal gambling. Cricket is thought to account for around 12 per cent of that global figure.

FLANAGAN URGES EDUCATION TO COMBAT FIXING: Flanagan stressed education for young players as the key to stamping out the scourge of fixing and said success should be measured by prevention -- not prosecutions. Cricket has battled for years against those seeking to rig both the overall outcome of matches and specific incidents within them, known as spot-fixing.

The ICC set up its Anti-Corruption Unit in 2000 after three international captains -- Hansie Cronje of South Africa, Pakistan's Salim Malik and India's Mohammad Azharuddin -- were banned for life for match-fixing.

With big-money Twenty20 leagues springing up around the world, attracting billions of dollars in illegal betting, the challenge remains enormous.

Flanagan said the ICC's goal was not just to catch the crooks but to stop the problem at source. "The main planks of our activity are prevention, disruption and only then investigation and prosecution -- in that order of priority," said Flanagan in an interview released by the ICC.

"Education of players, particularly young players, is absolutely crucial to make them aware of the evil intent of people out there who would seek to have them drawn into their clutches and who would seek to corrupt them."

Flanagan, formerly one of Britain´s most senior police officers, said cricket's approach was admired and imitated by other sports trying to wipe out rigging. "We shouldn't be judged by the number of prosecutions which have been engaged in," Flanagan said. "We should be judged by the level of prevention we are able to bring to bear, and I think that´s a very positive story."
