Tsipras: Greek prime minister is 'the greatest volatility factor'

"Up until yesterday," said the main opposition party leader, "[Mitsotakis] was announcing ballot list candidates and was feeding [election] dates to mass media."

But now, Tsipras added, "he remembered all about stability and that holding [early] national elections is not a responsible move for the nation. But who trusts him? He has lost control, and the more he stays in power the more he becomes an even greater volatility factor."
