Ousted Nissan boss Carlos Ghosn decided to flee Japan after learning that his trial had been delayed until April 2021 and also because he had not been allowed to speak to his wife, sources close to Ghosn said Thursday.

Ghosn, one of the world's best-known executives, has become Japan's most famous fugitive after he revealed Tuesday he had fled to Lebanon to escape what he called a "rigged" justice system.

Sources close to Ghosn said he learned at a recent court hearing that one of his two trials in Japan would be delayed until April 2021 from an original date of September 2020. There was not a firm date set for either trial but at least one was widely expected to start in April 2020.
