By Paul Carrel and Lefteris Papadimas BERLIN/ATHENS (Reuters) - Germany's parliament approved a third bailout for Greece on Wednesday after Finance Minister Wolfgang Schaeuble argued the country should get "a new start", while in Athens the government agonised over whether to call a snap election. The Bundestag's vote cleared one of the final obstacles to Greece getting funding so that it can make a 3.2 billion euro debt repayment to the European Central Bank on Thursday. In Athens, Prime Minister Alexis Tsipras and his inner circle debated whether to take on anti-bailout rebels within his own radical left Syriza party by calling a parliamentary confidence vote or to go straight to early elections.
