Greece’s center right opposition leader of the New Democracy party Kyriakos Mitsotakis has won a landslide victory in the country's snap election. Outgoing Prime Minister Alexis Tsipras and his left wing Syriza party have conceded defeat. Tsipras came to power in 2015 after promising to repeal punishing austerity measures. But he quickly made a U-turn and gave in to the demands of international creditors. Mitsotakis says the country is now entering a new post bailout era.
