Fifa has provisionally suspended its president Sepp Blatter, vice-president Michel Platini, and secretary general Jerome Valcke for 90 days.
Fifa’s ethics committee imposed the suspensions as part of its internal investigation into corruption at world football’s governing body.
In a statement, Fifa said “the grounds for these decisions are the investigations that are being carried out by the investigatory chamber of the Ethics Committee”.
All three men deny any wrongdoing.
Former Fifa vice-president Chung Mong-joon was also banned for six years and fined CHF 100,000 (£67,500).
“The proceedings against the South Korean football official Chung Mong-joon were opened in January 2015 based on findings in the report on the investigation into the bidding process for the 2018/2022 FIFA World Cups. He has been found guilty of infringing article 13 (General rules of conduct), article 16 (Confidentiality), article 18 (Duty of disclosure, cooperation and reporting), article 41 (Obligation of the parties to collaborate) and article 42 (General obligation to collaborate) of the FIFA Code of Ethics.”
The punishments will have a major impact on who will lead Fifa after the presidential election set for 26 February 2016, for which both Platini and Chung had hoped to replace Blatter.
