Following the 2013 state election, a red-green coalition between the SPD and Greens was formed, holding a one-seat majority in the Landtag. After Green parliamentarian Elke Twesten controversially defected to the CDU on 4 August 2017, the coalition lost its majority,[1] which prompted Minister-President Stephan Weil to schedule an early election for 15 October.[2] The Landtag was officially dissolved on 21 August after 135 of 137 parliamentarians voted in favor, with 91 votes required for its dissolution.[3]
Electoral system
The Landtag of Lower Saxony is elected using mixed-member proportional representation. Its minimum size is 135 seats. Of these, 87 are elected in single-member constituencies, and the remainder are determined by party lists. Voters have two votes: the "first vote" for candidates within each individual constituency, and the "second vote" for party lists. There is an electoral threshold of 5% of second vote to qualify for seats. Seats are allocated using the d'Hondt method, with additional overhang and leveling seats provided to ensure proportionality. The normal term of the Landtag is 5 years.[4]

Neither the incumbent red-green coalition between the SPD and Greens nor the black-yellow opposition of the CDU and FDP secured a majority of seats in the election. Because the FDP ruled out the possibility of a traffic light coalition (between the SPD, FDP, and Greens) and the Greens ruled out a Jamaica coalition (between the CDU, Greens, and FDP),[5] the SPD and CDU subsequently agreed to start negotiations to form a grand coalition.[6]
On 16 November, the SPD and CDU agreed to form a government.[7]
