Greek Conservatives Oust Leftist Premier Tsipras Ken Bredemeier Conservative Greek opposition leader Kyriakos Mitsotakis rode to a landslide victory over leftist Prime Minister Alexis Tsipras in Sunday's parliamentary elections and is set to become the country's new head of government Monday. Tsipras, rejected as the Greek leader after four years, said he called Mitsotakis, the son of a former prime minister, to congratulate him on his victory. A combined survey of Greece's main TV stations showed Mitsotakis's New Democracy party leading Tsipras' Syriza party by an average of 39.8% to 31.6%. If the trends hold, the 51-year-old Mitsotakis, a graduate of Harvard in the U.S., would have a 158-seat majority in the 300-member parliament. .
