Who is who in German federal election Christian Democrats. Centre-right alliance of Angela Merkel’s CDU and Bavarian Christian Social Union (CSU) faces serious challenge from right for first time in post-war history Social Democrats (SPD). Support for centre-left party surged when former European Parliament president Martin Schulz launched his campaign, but it now trails badly The Left (Linke). Party with roots in communist East Germany – led by polarising figure Sahra Wagenknecht and co-chairman Dietmar Bartsh – is least likely to be part of governing coalition Greens (Grüne). Support has dropped to single digits this year but co-chairs Katrin Göring- Eckardt and Cem Özdemir could be kingmakers in coalition with Merkel’s CDU Liberal Free Democratic party (FDP). Junior coalition partner in Merkel’s second term. Could return to parliament – and possibly government – under new leader Christian Lindner Alternative for Germany (AfD). Despite infighting, remains on course to be first far-right party to enter Bundestag since World War II. Lead candidates are Alice Weidel and Alexander Gauland PREDICTED SHARE OF BUNDESTAG SEATS (%) 36.5 CDU- CSU 23.5 SPD 11 AfD 10.5 The Left 9 FDP 6 Greens INSA survey of 2,054 people between Sep 8-11.
