Show Hide image 15 May 2012 Chart of the day: Greek coalition talks fail The final round of talks to form a coalition government in Greece fell apart today, causing large falls in a matter of seconds on the Athens Stock Exchange. With no stable coalition possible, talks now turn to forming a caretaker government until fresh elections are held, most likely on June 17. It is widely expected that the radical left-wing coalition Syriza will take first place in these elections, which would give it fifty bonus seats under a Greek electoral law designed to ensure that the largest party always forms a coalition. Syriza's strong anti-austerity stance will spark confrontation with European authorities, and could lead to a Greek exit from the Euro – or even an end to the Euro altogether.
