The International Olympic Committee (IOC) in Lausanne on Thursday will examine allegations of corruption against two of its members, Issa Hayatou and Lamine Diack, while the other involved, Joao Havelange, resigned and is protected against any disciplinary sanction.

The 15 members of the executive committee will hear the report of the ethics committee formed a year ago to investigate three IOC members allged to have received bribes, according to a program unveiled by the BBC in November 2010.

Lamine Diack of Senegal, who also chairs the International Association of Athletics Federation (IAAF), and Cameroon's Issa Hayatou, president of the Confederation of African Football (CAF), are suspected of having received money in exchange for contracts from the company ISL Marketing, which went bankrupt in 2001.

The two men have the right to come to Lausanne to explain themselves to the executive committee on Thursday, which could decide on penalties ranging from a simple warning to their exclusion from the IOC.

Joao Havelange, 95, also allegedly received money from ISL, according to the BBC documentary, but decided to resign so as not to be exposed to penalties.

Havelange, who was president of FIFA for 24 years, however, could be affected by the publication of court documents relating to ISL, which promised a succession to FIFA president Sepp Blatter.

According to the BBC, Havelange received the most money from ISL, up to a million dollars in exchange for awarding contracts to promote the World Cup.
