The German EU Commissioner Günther Oettinger (CDU) also spoke in favour of an alliance with the SPD: "A grand coalition is good for Europe." Even Luxembourg's Prime Minister Jean-Claude Juncker argued indirectly for a black-red coalition. He warned that there were lessons to be drawn from the good performance of the eurosceptical "Alternative for Germany". "The success of the AfD means that we have a communication problem vis-à-vis the population", Juncker said. From a grand coalition of CDU and SPD, Juncker expects "more considerate manners" towards Germany's European partners than in the past.
Union parliamentary leader Volker Kauder (CDU), however, urged in an interview with the Spiegel that the SPD should not unnecessarily delay coalition negotiations with the CDU. Although one should take time for negotiations, Kauder said that "Europe is not waiting for the government in Germany to be formed - we must be able to act". Kauder stressed further that in his view, an alliance with the SPD was preferable to a coalition with the Greens.
