The Social Democrats sink to a new low, and the populist AfD could lead the opposition, DW reported in its live updates on German election on Sunday.

Angela Merkel's Christian Democrats stretch their lead as the strongest force in parliament, despite a nine-percent dip compared to their 2013 haul. 

Martin Schulz's Social Democrats slip to 20%, their worst election result in post-war Germany.

Right-wing populist Alternative for Germany (AfD) wins its first seats in the federal parliament, also becoming the Bundestag's third power in the process. 

The pro-business Free Democrats are returning to parliament, after missing the cut for the first time since the war last time around.

The Greens and the Left hold station, scoring very similarly to four years ago. 

No coalitions are practically viable without Merkel's CDU taking the lead. However, a repeat of the current "Grand Coalition" with the Social Democrats is not the chancellor's only option, according to the publication.
