Syriza leader Alexis Tsipras greets supporters following victory in the election in Athens on January 25, 2015.  Greek Prime Minister Antonis Samaras  said the nation 'had spoken' in handing victory to the anti-austerity Syriza party, and said he hoped the new government would not endanger the country's EU and euro membership.  'I hand over a country that is part of the EU and the euro. For the good of this country, I hope the next government will maintain what has been achieved,' Samaras said in a brief address to reporters.
