See main article: 2018 German government crisis. In June 2018, a government crisis erupted within the cabinet between Interior Minister and CSU Chairman Horst Seehofer and Chancellor Angela Merkel, after Seehofer had elaborated a masterplan on asylum policies, containing the rejection of asylum seekers already registered in other EU countries.[1] Seehofer had threatened to resign over the crisis on 1 July, but an agreement was made between the CDU/CSU sister parties on 2 July.[2]
The results of the 2017 election had necessitated a series of negotiations that required the Merkel III cabinet to remain in a caretaker capacity for a prolonged period of time (into 2018). Government formation after the 2021 elections lasted until 24 November 2021,[3] and the caretaker government continued until December 8,[4] making Merkel just 9 days short of the record for longest-serving Chancellor in post-war German history ahead of Helmut Kohl.[5]
