Showdown Underway; New Democracy Party Wants Rollbacks on Austerity Measures
The very instant the Greek "Unity Government" formed it was divided. Antonis Samaras, the leader of Greece’s New Democracy Party, one of the three coalition parties that formed the government says he will not sign a document demanded by the IMF before it will release the next tranche.
That's not all, Samaras actually wants to rework the agreement. Neither will fly (at least with Greece receiving the next tranche of money), and tensions fester. Source
