The CDU won in a landslide, claiming 43% of the vote with a swing of over eleven percentage points and falling one seat short of an absolute majority in the Landtag.

The FDP also declined to 6% and the Alternative for Germany (AfD) fell below the 5% electoral threshold, losing representation in a state parliament for the first time.

The South Schleswig Voters' Association (SSW), which represents the Danish and Frisian minorities in Schleswig-Holstein, won 6%, their best result since the first post-war state election in 1947.

[1] The CDU's victory was attributed to the personal popularity of Minister-President Günther, as well as the federal government's response to the 2022 Russian invasion of Ukraine, for which Chancellor Olaf Scholz has been criticised.

[6] In the previous election held on 7 May 2017, the CDU remained the largest party with 32.0% of votes cast, an increase of 1.2 percentage points.

After the election, Minister-President Günther stated his intention to seek a renewal of the incumbent Jamaica coalition with both the Greens and FDP.

Agreement was also found in policy areas such as digitalisation and education, while they disagreed on security, agriculture, transport, and housing.

[16] The agreement was approved overwhelmingly by both parties' congresses on 27 June, with the Greens recording four dissenting votes and the CDU none.
