BEIRUT — Ex-Nissan boss Carlos Ghosn has answered hundreds of questions by French investigators over the past week in Beirut and was “happy and satisfied” to have had the opportunity to explain himself over accusations of financial misconduct, his lawyers said Friday. The four and a half days of questioning marked the first opportunity for Ghosn, a French national, to defend himself against the French allegations — including spending on lavish parties and private planes — since his 2018 bombshell arrest in Japan and escape to Lebanon a year later. However, as Ghosn was being interrogated outside of French soil, it was unclear how he could, if at all, be handed down preliminary charges. His lawyers said they will now seek the right to ask for witnesses and expert testimony in the French investigation.
