Greece faces last chance to stay in euro as cash runs out

Greek Prime Minister Alexis Tsipras is expected to present new proposals to an emergency euro zone summit on Tuesday, under pressure from European leaders to come up with credible ideas as his country's banks face potential meltdown.

With Greek lenders down to their last few days of cash and the European Central Bank tightening the noose on their funding, Tsipras must persuade the bloc's other 18 leaders, many of whom are exasperated with five years of crisis, to open negotiations fast on a new loan to rescue Greece.
