If Greece and its creditors strike a deal in Brussels, the immediate challenge for Prime Minister Tsipras will be at home, where he’ll have to deal with the opposition from within Syriza.
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.
As Syriza’s junior coalition partner, the Independent Greeks, have also indicated that they could withdraw from the government, Tsipras could be left having to rely on the support of the opposition New Democracy.
Greece’s opposition centrist party, To Potami, has announced that it would join other mainstream opposition parties — including the remains of traditional centre-left PASOK, and the parliament’s second-largest party, centre-right New Democracy — in backing the plan.
Their leader, Stavros Theodorakis, said his party would back a deal, but also wants to add more pro-growth measures. Alexis Tsipras will need to reshuffle his governing coalition if the Greek parliament does fail to back the latest offer. In an interview with the Financial Times Theodorakis, said he discussed the possibility of such a reshuffle with Mr Tsipras during meetings last week, and predicted there would be “a lot of objections” from the prime minister’s far-left Syriza party when the measures are put to a vote.
“That is something that will be discussed, and Tsipras will face, after passing the agreement through parliament, after he sees which members of his party — or members of his government — did not vote for the agreement,” Theodorakis said during his interview with the Financial Times.
Ex Deputy Prime Minister and PASOK deputy Evangelos Venizelos told Italy’s La Repubblica: "The agreement with the creditors is the only possible solution. Tsipras do not have the mandate to lead the country out of the single currency area. A possible Grexit would arise a serious question of democratic legitimacy" adding that PASOK will back the plan if Tsipras is honest.
New Democracy leader and former Prime Minister Antonis Samaras said that his party was ready to join a unity government in order to keep Greece in the euro zone. In an interview with Crash magazine, Samaras estimated that “a new national unity government will be necessary, if the new reform plan will not pass parliament”.
If the Greek parliament does fail to back the latest offer Tsipras might resort to calling a referendum or new elections an option which was evaluated as “catastrophic” by Samaras.
