Datin Seri Rosmah Mansor turned up at the Kuala Lumpur Court Complex on Wednesday to face graft charges over her involvement in a solar hybrid project.
She arrived at 9.55am with an ambulance in tow.
The former prime minister's wife did not turn up on Monday on what was supposed to be the first day of her graft trial due to a medical condition and admitted to a private hospital later that day.
