A monumental moment in Greek politics happened when Vassiliki Thanou, president of the country's Supreme Court, was sworn in as the first female prime minister in the nation's history. The 65-year-old justice was named to head a caretaker government until the country holds early elections next month.After a final effort to get political party leaders to form a coalition led by former Energy Minster Panagiotis Lafazanis failed, President Prokopis Pavlopoulos was obligated to appoint a caretaker administration. She has been the President of the Court of Cassation, one of Greece's three supreme courts, since 1 July 2015, and is currently the most senior judge in Greece.
