Three days after being questioned by authorities, Blatter is back behind his desk.

Sepp Blatter was back at work at Fifa headquarters on Monday, three days after being questioned by Swiss investigators over payments he authorised to former Conmebol chief Jack Warner and Uefa president Michel Platini.

The FIFA president is scheduled to speak at a staff meeting, which is being characterised as a regular gathering that takes place at least once a month rather than the stage for a sudden announcement.

Blatter was asked by Swiss investigators on Friday why Fifa paid two million Swiss francs (about £1.3m) to Platini in 2011 for work supposedly carried out between 1998 and 2002. he was also being questioned over the sale of Caribbean TV rights to disgraced former Fifa exco member, Jack Warner.

The longstanding Fifa president is awaiting a possible announcement from the Fifa ethics committee on whether he will be suspended as a result of the Swiss investigation into possible criminal mismanagement and misappropriation of Fifa money.

Blatter adviser Klaus Stoehlker told The Associated Press about the staff meeting, which is planned for 4 p.m. local time.

But the 79-year-old was back in his office that was raided on Friday, attempting to convey a ‘business as usual’ message to Fifa staff and observers.

“There is a meeting this afternoon,” Stoehlker told The Associated Press.

“He’s giving them (staff) information at 4pm.”

Stoehlker worked with Blatter on his re-election campaign in May and said he continues to advise him.

“Twenty four hours ago he had no idea [plan] about leaving [Fifa],” Stoehlker said in a telephone interview.

“There are so many lawyers and it depends what they say and what kind of risks they are putting on the wall.”

Blatter is due to stand down after February’s election, but in the wake of Friday’s announcement that he was being question by the office of the attorney general, there have been calls for him to stand down immediately
