Greek Prime Minister Alexis Tsipras announced his resignation and called for snap elections, as he went on the offensive to defend the country’s massive bailout after it triggered a rebellion within his own hard-left party. Tsipras did not give a date for the new polls but they are expected to be held on September 20, the state news agency ANA said, citing government sources. In a live televised address to the nation, the 41 year old premier said he had worked hard to secure the best possible rescue package for his country, but he now needed a clear mandate from the Greek people after it cost him his parliamentary majority. “Now that this difficult cycle has come to an end, I wish to submit to your judgement all that we have done,” Tsipras said before meeting President Prokopis Pavlopoulous to formally hand in his resignation. The move leaves Greece in the hands of a caretaker government until the vote. Tsipras announcement came on the same day the debt crippled country received its first 13 billion euros in bailout cash on Thursday. The hard won bailout has divided Tsipras Syriza party after it stormed to power in January on an anti-austerity platform. Greek MPs on Friday approved the new rescue deal but 43 of Syriza’s 149 MPs either rebelled or abstained from the vote, forcing the premier to rely on the opposition for support.
