Alexis Tsipras has vowed to serve a full four-year term as Greece's Prime Minister – after weary voters took part in the country's fifth general election since 2009. It is a decisive victory, as opinion polls conducted on Friday had put Mr Tsipras and Vangelis Meimarakis, his conservative rival, just half a percentage point apart. However, Syriza is still six seats short of an overall majority, meaning the left-wing party has to form a coalition with the Independent Greeks – a right-wing group with 10 seats.
