South Korean FIFA presidential candidate Chung Mong-joon has accused the organisation of leaking false information in an attempt to discredit him ahead of the elections in February 2016.
It was reported last week that FIFA ethics committee it was investigating charity donations made by Chung in 2010.
The former FIFA vice-president donated US$400 000 to Pakistan after floods there and $500 000 to Haiti after the catastrophic earthquake in that country.
It has since been suggested that Chung used the donations to gain political favour, but he denied this in a statement released on Tuesday.
“Whether or not the upcoming FIFA presidential election takes place according to due process, fairness and openness will be the litmus test for whether or not genuine reform of FIFA will be possible,” the South China Morning Post reports the statement to have read.
“Only a fair and open election can resuscitate FIFA's reputation which has been gravely undermined by scandals old and new.
“Unfortunately, there are increasing signs that the election is deteriorating into a typical FIFA affair with selective leaks of so-called ‘confidential’ information, accusations of wrong-doing based on ‘unconfirmed reports’, un-named ‘sources’ and ‘insiders’.
“The recent press reports attacking Dr Chung’s character and integrity are based on such unconfirmed, leaked sources and full of factual distortions.
“To be clear, contrary to recent press reports based on FIFA leaks, Dr Chung is not facing any criminal charges or allegations of bribery, fraud, corruption, vote buying or even a breach of ‘conflict of interest’ under the FIFA ethics code from the ethics committee.
“Beyond that, Dr Chung refrains from commenting on any possible ethics committee proceedings out of respect for confidentiality requests made by FIFA.
“However, by leaking information that could only have come from within FIFA, FIFA is violating its own rules and regulations that it imposes upon others.
“Indeed, the current election is in danger of being manipulated to a degree unseen even in previous notorious FIFA presidential elections.”
Chung announced his candidacy for the FIFA presidential race in Paris last week. He served as a FIFA vice-president from 1994 to 2011 and Korea Football Association chairman from 1993 to 2009.
