The Greek government is acting increasingly irresponsibly, including towards its own people, said the secretary general of Germany's Social Democrats (SPD), junior partner in Chancellor Angela Merkel's ruling coalition. "In our view, the Greek government is behaving increasingly irresponsibly, including towards its own country," SPD Secretary Yasmin Fahimi said on Monday. "The mood in the SPD party leadership is above all one of concern with regard to Greece." "Solidarity is not a one-way street," she told reporters.
