The Christian Democratic Union (CDU) led by Alfred Gomolka emerged as the largest party with 38.3% of the vote, followed by the Social Democratic Party (SPD) with 27.0%. The CDU subsequently formed a coalition with the Free Democratic Party (FDP), and Gomolka became Mecklenburg-Vorpommern's first post-reunification Minister-President.
