A report by the official IRNA news agency today says Hasan Rouhani named Mohammad Nahavandian, a 58-year-old businessman with a doctorate in economics from George Washington University in Washington.
Rouhani was elected in June and was endorsed by the country's Supreme Leader yesterday, allowing him to begin acting as president. He will be sworn in later today.
In his speech yesterday, Rouhani said his top priority is to resolve economic problems. Nahavandian's appointment is seen as outreach to the private sector.
