European Commission President Jean-Claude Juncker declined on Saturday to take a phone call from Greek Prime Minister Alexis Tsipras because Athens has not yet sent in reform proposals that it promised for Thursday, an EU official said. "The Greek prime minister requested a phone call for 1100 CET on Saturday, but Juncker declined because there has been no progress in the discussions and proposals that the Greek side promised on Wednesday night to deliver on Thursday have not arrived," the official said. Tsipras was also due to return to Brussels for further discussions in person on Friday, but didn't.
