Former Nissan Motor Co. Chairman Carlos Ghosn plans to name those he thinks were behind his 2018 arrest for alleged financial misconduct, including some in the Japanese government, at a news conference on Wednesday, a U.S. broadcaster said Tuesday.

Later the same day, Tokyo prosecutors obtained an arrest warrant for his wife, Carole, for alleged perjury. According to the prosecutors' special investigation squad, Carole was suspected of having made a false statement during a witness examination at the Tokyo District Court last April.

Carlos Ghosn had been facing trial in Japan on charges of financial misconduct, which he denies, before fleeing Japan late last month for Lebanon.
