Greece's president has appointed the head of the country's Supreme Court as prime minister to lead a caretaker government as the country heads to early elections next month.

President Prokopis Pavlopoulos named Vassiliki Thanou as Greece's new prime minister Thursday, making her the country's first woman to hold the position.

Thanou, 65, was to be sworn in Thursday evening, and will then appoint a Cabinet that will be sworn in Friday. Elections are expected Sept. 20.

Outgoing Prime Minister Alexis Tsipras resigned last week barely seven months after his election. His coalition government suffered a rebellion from within his left-wing Syriza party over his acceptance of the austerity terms tied to the country's new international bailout.
