Even if Greece and its creditors strike a deal in Brussels analysts fear that Tsipras will find it very hard to get political support for a bailout deal which goes beyond the political mandate that brought his leftist government into power.
Greece’s opposition parties including the remains of traditional centre-left PASOK, the parliament’s second-largest party, centre-right New Democracy; and centrist party, To Potami, has announced that they would all back the plan to avert a slide out of the single currency area.
In an interview for Crash magazine, Samaras estimated that a new national unity government will be necessary, if the new reform plan will not pass parliament.
A government official replied to the statements saying that Syriza rules out any possibility of forming a national unity government. “These proposals bring back to mind the Apostasy of 1965” the official said.
The terms Apostasy of 1965 or Iouliana was a political crisis in Greece that centred on the resignation, on 15 July 1965, of Prime Minister Georgios Papandreou and the appointment, by King Constantine II, of successive Prime Ministers from Papandreou's own party, the Center Union, to replace him. Those defectors from the Center Union were branded, by Papandreou's sympathizers, as the Apostates ("renegades"). The Apostasy heralded a prolonged period of political instability, which weakened the fragile post-Civil War order and ultimately led to a coup d'état in 1967.
