The president of the Japanese Olympic Committee is expected to announce his intention to resign at Tuesday's JOC board meeting. Sources say he will resign when his current term expires in June.
Tsunekazu Takeda has been facing corruption allegations in France in connection with Tokyo's successful bid for the 2020 Olympics. He headed the bidding committee.
Prosecutors in France say an investigative judge has been considering whether to indict Takeda since December last year.
Takeda maintains his innocence. However, the IOC has expressed concern about the scandal's potential to negatively impact the Games. And calls for his resignation have been growing in and outside Japan.
The sources say he is resigning out of consideration for the Games, which begin in 16 months' time.
