Under Seehofer's master plan Germany would reject migrants who have already been deported or have an entry ban and would instruct police to turn away all migrants who have registered elsewhere in the EU, no matter if these countries agreed to take them back. Merkel feared that unilaterally sending migrants back to neighbouring countries without seeking a multilateral European agreement could endanger the stability of the European Union. In June 2018, Seehofer backed down from a threat to bypass her in the disagreement over immigration policy until she would come back on July 1 from attempts to find a solution at European level. During these weeks the media was speculating not only on a government fall down but also on a split of the CDU/CSU alliance, which consists of the CSU in Bavaria and the CDU in the remaining 15 states. It would have meant that the CSU would run for elections all over Germany and the CDU would run in Bavaria, which they have never done before.
