Swiss prosecutors have launched legal proceedings against Fifa president Gianni Infantino.
According to the BBC, the action is in relation to an alleged secret meeting the head of world football’s governing body held with the Swiss attorney general Michael Lauber.
Lauber last week offered to resign after a court said he covered up the meeting and lied to supervisors during an investigation by his office into corruption surrounding Fifa.
Both have denied any wrongdoing.
Fifa said Infantino and the governing body would “co-operate fully with this investigation”.
In a statement released through Fifa, Infantino said: “As president of Fifa, it has been my aim from day one, and it remains my aim, to assist the authorities with investigating past wrongdoings at Fifa. Fifa officials have met with prosecutors in other jurisdictions across the world for exactly these purposes.”
