The opposition Christian Democratic Union (CDU) returned as the largest party after falling to second in 1966, winning a narrow plurality of 46.3%, with a lead of 0.2% and one seat over the SPD. The FDP suffered losses and declined to 5.5%. Overall, the incumbent coalition retained a reduced majority of 105 seats. However, a number of FDP deputies opposed to cooperation with the SPD refused to vote for Kühn in the investiture vote on 28 July; he was re-elected with the minimum majority of 101 votes out of 200. There were 95 votes for CDU leader Heinrich Köppler and four abstentions.^[1] In October, three members of the FDP faction defected to the new party National Liberal Action, leaving the government with a narrow majority of 102 seats.^[2] Nonetheless, it completed its full term.

Electoral system

The Landtag was elected via mixed-member proportional representation. 150 members were elected in single-member constituencies via first-past-the-post voting, and fifty were then allocated using compensatory proportional representation. A single ballot was used for both. An electoral threshold of 5% of valid votes is applied to the Landtag; parties below this threshold are ineligible to receive seats.

Background

Main article: 1966 North Rhine-Westphalia state election

In the previous election held on 10 July 1966, the SPD became the largest party for the first time in the state, coming just short of a majority with 49.5% and 99 seats. The CDU was reduced to second place with 43%, and the FDP improved to 7.4%. The incumbent CDU–FDP coalition was renewed, but collapsed in November after a grand coalition took power federally. The FDP subsequently agreed to a coalition with the SPD, and Heinz Kühn was elected Minister-President by the Landtag.
