The battle lines between Greece and the rest of Europe were drawn up on Tuesday when Syriza called off the planned privatization of Greece's Port of Piraeus. Then on Wednesday, the party, led by Alexis Tsipras, announced the reintroduction of the minimum wage, as well as the rehiring of sacked government workers and a halt to other privatization schemes.
Also on Syriza's agenda is easing the repayment terms of the 240 billion euros ($295 billion) in loans the country has received since the height of its financial crisis in 2010—a hope that German politicians such as Finance Minister Wolfgang Schaeuble have been quick to dismiss this week. The bailout came with strict conditions on government spending and structural reforms. These measures have had a crippling effect on the Greek economy and renegotiating them has been a key part of Syriza's election campaign.

If Syriza had hoped for more sympathy from France—which has itself missed several deadlines to lower its budget deficit—Macron looked to bury them on Thursday.
"All the European governments are exposed to Greek debt, so we will have a negotiation, but the with the Commission, with the ECB (European Central Bank)," he told CNBC. "But for me, there is no specific waiver due to the new political situation."
Other than France, Greece may also look for backing from other southern European members of the single currency union, some of whom are struggling with their own debt burdens.
Whether this will translate into policy change on the part of the ECB or European Commission, the executive arm of the European Union, is seen as doubtful however.
"We think that these countries will find it very difficult to meet Syriza's demands of a writedown, while at the same time cancelling most of the reforms adopted during the adjustment program," said Jakob Christensen, senior economist at Exotix Fixed Income, in a research note last Friday.
