Greece on Wednesday geared up for a parliamentary vote on draconian reforms demanded by eurozone creditors in exchange for a huge new bailout, in what could be Prime Minister Alexis Tsipras’s toughest political test yet. The last ditch deal struck Monday saw Tsipras agree to sweeping changes to labour laws, pensions, VAT and other taxes in exchange for new funds to keep Greece’s struggling economy alive. The parliament in Athens must approve the deal before the 18 other eurozone leaders start negotiations over what Greece is to get in return: a three year bailout worth up to 86 billion euros, it’s third rescue programme in five years. But while the motion is expected to pass, Tsipras has been forced to turn to pro-European opposition parties to get it through in the face of opposition from some thirty rebel lawmakers in his own radical left Syriza party, raising questions about his political survival. The embattled premier said he took “full responsibility” for signing an accord he did “not believe in, but which I signed to avoid disaster for the country” as it teetered on the brink of economic collapse. “A prime minister must fight, speak the truth, take decisions and not run away,” Tsipras said in a TV interview when asked wether he would resign if the reforms fail to pass or he loses his parliamentary majority. Civil servants are set to stage a 24-hour strike on Wednesday while several in Syriza have vowed to vote against the plans, which contradict much of their own agenda.
