Sepp Blatter on Monday said he would remain president of FIFA, reiterating that “he had done nothing illegal or improper” after criminal proceedings were opened against him lastFriday by the Swiss attorney general. Though Blatter returned to work just three days after being interrogated by Swiss investigators, he is now awaiting a possible announcement from the FIFA ethicscommittee on whether he will be suspended as a result of the Swiss investigation into possible criminal mismanagement and misappropriation of FIFA money. “President Blatter spoke to FIFA stafftoday and informed the staff that he was cooperating with the authorities, reiterated that he had done nothing illegal or improper and stated that he would remain as president of FIFA,”Lorenz Erni, Blatter’s lawyer, said in a statement.
