The far-right Alternative for Germany (AfD) party won a position of executive power for the first time. Its candidate, Robert Sesselmann, became district administrator, or head of a county, in local elections on Sunday.
Sesselmann, a lawyer and regional lawmaker, beat incumbent Jürgen Köpper of the center-right Christian Democratic Union in a second-round runoff election in Sonneberg county in the eastern state of Thuringia.
Official results showed Sesselmann winning 52.8% to 47.2%.
AfD's win comes as its support surges in national polls, from 10% last June to 18% today. At the same time, support has plummeted for Chancellor Olaf Scholz's coalition, composed of his center-left Social Democratic Party, the Greens and the Free Democratic Party.
