• German election results in full

The German constituency held by Angela Merkel for the last 30 years has flipped to a 27-year-old politician from the Social Democratic party (SPD), in the starkest expression yet of a generational change of guard underlying Sunday's national vote.

Germany's outgoing chancellor had continuously won a direct mandate in the electoral district of Vorpommern-Rugen - Vorpommern-Greifswald I since it was created after reunification in 1990.
