Following the
2017 Lower Saxony state election, the incumbent
red-green coalition government of minister-president
Stephan Weil was 2 seats short of a majority in the Landtag. Due to FDP leader
Stefan Birkner ruling out any coalition with SPD or Greens, and the Greens ruling out any coalition with CDU and FDP, the only option for a majority government was a
grand coalition of SPD and CDU, considering no party wanted to form a coalition with the AfD. On 22 November 2017, Weil was reelected as minister-president receiving 104 out of 137 votes as the head of a grand coalition. ==Electoral system==
