Democratic Party of Japan President Ichiro Ozawa indicated Tuesday he will decide whether to resign by March 24 depending on what charges, if any, are brought against his chief secretary, Takanori Okubo.

Prosecutors have until that day to bring charges against Okubo, who was arrested March 3 for allegedly receiving illegal corporate donations.

"There will be a judgment from the prosecutors in the near future. . . . When the judgment is disclosed, I will make a decision about my future," Ozawa told a news conference.
