GERMANY - As Chancellor Merkel's grip on power continues to look more and more fragile, Bild Zeitung reports that Germany’s Christian Social Union party will give her a two-week deadline to meet its demands for overhauling asylum policy. If true, the reports would be an unprecedented challenge to Merkel's authority and risks plunging the nation further into chaos, as Der Spiegel pulls no punches in explaining: "The German question… How do we deal with migrants? Endangers Merkel's chancellorship." However it ends, the spat has laid bare the limits of Merkel's authority in a fractious government that took office in March after nearly six months of post-election haggling.
