The Cameroonian is one of three officials alongside Hong Kong's Timothy Fok and General Mounir Sabet of Egypt to graduate to honorary IOC member status at the beginning of 2017 after passing one of the two maximum age limits.

It has been widely reported that the Egyptian Competition Authority have specifically referred Hayatou to prosecutors as part of a probe into an alleged abuse of his CAF position.

He is supposedly suspected of awarding broadcast rights to the Lagardere Sports media company without opening up the tender process.

A "free and fair" tender process is required under Egyptian law; something relevant because CAF is based in Cairo.

CAF, however, have since claimed the prosecution is based on "false information" and claim Hayatou is not personally implicated.

"It should be noted that in the letter sent to CAF by the Egyptian Competition Authority, there is no mention of any prosecution against the President of CAF, whether for acts of corruption or something else," they claimed.

London-based Lagardere also insist the allegation is "wholly unfounded".

"CAF renewed the appointment of Lagardère Sports as marketing and media agency for the main regional football competitions in Africa up to 2028, in accordance with the clearly defined renewal process under the existing rights agreement," a spokesperson told insidethegames.

"A legally binding agreement was signed by the parties in June 2015 and was unanimously approved by the CAF Executive Committee. 

"Although Lagardère Sports is not the subject of the correspondence from the Egyptian competition authorities, any allegations that the agreement breaches local Egyptian competition laws are wholly unfounded and we have clear and categorical legal advice to that effect."

But it is possible the incident could put pressure on Hayatou as he seeks to extend his 28-year tenure as President of CAF.

Hayatou served as interim FIFA President last year before the election of Gianni Infantino as a permanent replacement for Sepp Blatter.

At the IOC, an age limit of 70 exists for those who joined sport's most exclusive club after 1999 while those that joined beforehand must not exceed the age of 80.

Both Hayatou and Fok, who each joined in 2001, celebrated their 70th birthdays in 2016.

General Sabet also ends a 19-year tenure having passed the milestone of 80.

All three were approved for honorary membership - something that is not an automatic pre-requisite - at the IOC Session in Rio de Janeiro last August. 

They are still currently listed as serving members on the IOC website but their names are expected to be removed soon.

There are currently 95 IOC members in total.

This number includes Ireland's Patrick Hickey, who is currently "temporarily self-suspended" pending the outcome of a Brazilian investigation into an alleged ticketing scam, which he denies, at Rio 2016.

The only other member who appears a contender to leave his position before the September 13 vote for the host city of the 2024 Olympic and Paralympic Games is Great Britain's International Paralympic Committee President Sir Philip Craven.

His successor is due to be elected just five days earlier, on September 8 in Abu Dhabi, so it is possible that he may remain in his IOC position for the following week's Session in Lima.

Seven other members - Pál Schmitt and Dániel Gyurta from Hungary, Angela Ruggiero, Anita DeFrantz and Larry Probst from United States, and Tony Estanguet and Guy Drut from France - will be unable to participate in the 2024 vote due to coming from one of the three contenders: Budapest, Los Angeles and Paris.

They would be able to participate in later rounds if their respective cities are eliminated.

Germany's Thomas Bach, as IOC President, is also expected to not vote.

This means that, as it stands, a maximum of between 88 and 90 appear likely to vote in the first round, depending on the participation of Hickey and Sir Philip as well as the number of absentees.

Japanese Olympic Committee President Tsunekazu Takeda is the only IOC member due to reach an age limit, of 70, in 2017.

The Agenda 2020 reforms passed in 2014 allowed up to five exceptions to the 70 age limit for a maximum of four years.

Switzerland's Gian-Franco Kasper and Spain's José Perurena, the respective Presidents of the International Ski Federation and International Canoe Federation, are current exceptions and are expected to remain so throughout 2017.
