Greece's Tsipras Vows 'Thus Far and No Further'

Greek Prime Minister Alexis Tsipras is struggling to contain a revolt in his left-wing Syriza party. He said on Wednesday that his government would not implement reform measures beyond those agreed with lenders at a euro zone summit this month. Tsipras faces a tough Syriza central committee session on Thursday, as many activists were angered by his acceptance of bailout terms more stringent than those voters rejected in a July 5th referendum. In a clear warning to party rebels, Tsipras said he could be forced to call early elections if he no longer had a parliamentary majority. He suggested an emergency party congress could be held in early September.
