Mr Tsipras, should he become Prime Minister, has pledged to keep the euro but vowed to cease enforcing the bail-out demands made on Greece "from his first day in office." The likely implication of such a move is a forcible Greek exit from EMU as markets take fright. Syriza however are taking a gamble that Europe's leaders will fight to keep the union together after throwing so much money at the country to keep it afloat. Time will now tell if the gamble pays off.
