A phone call on Sunday between German Chancellor Angela Merkel, French President Francois Hollande and Greek Prime Minister Alexis Tsipras took place in a "constructive" atmosphere, the German government said on Monday. Asked about the call at a regular news conference, Merkel's spokesman Steffen Seibert declined to provide further details and said Greece would not be a central topic of discussion on Monday evening at a meeting between Merkel, Hollande and European Commission President Jean-Claude Juncker in Berlin. "I don't want to say that Greece won't be discussed on the margins, but it won't be the main theme," said Seibert.
