The Christian Democrats (CDU) have won elections in North Rhine-Westphalia (NRW), but voters worried about global heating have rendered the pro-renewables Green Party the kingmaker for a future government in Germany’s most populous state.

The CDU under incumbent state premier Hendrik Wüst gained 35.7% (+ 2.7 percentage points), according to preliminary results, while the rival Social Democrats (SPD) of German Chancellor Olaf Scholz had their worst post-war result with 26.7% (- 4.5 pcp) in the heavily industrialised state that used to be its greatest stronghold due to a strong workers and union base.
