Greece's Prime Minister Alexis Tsipras, makes a secular oath to the Greek President Karolos Papoulias at the Presidential Palace in Athens, Monday, Jan. 26, 2015. Radical left leader Alexis Tsipras has been sworn in as Greece's new prime minister, becoming the youngest man to hold the post in 150 years. The 40-year-old broke with tradition and took a secular oath rather than the Greek Orthodox religious ceremony with which prime ministers are usually sworn in.(AP Photo/Petros Giannakouris)
