Syriza leader Alexis Tsipras votes at a polling station in Athens in the second round of Greece's general elections, with the leftist former premier facing an uphill battle to overturn a 20 percentage point deficit against conservative front-runner Kyriakos Mitsotakis. Tsipras, whose call for wage hikes has so far failed to garner momentum, warns against giving Mitsotakis a blank cheque to carry out an agenda of policies unwinding social benefits, arguing for a "strong opposition... to balance the political system and our democracy".
