Germany held parliamentary elections on September 24. The CDU/CSU bloc won the election with 33 percent of the vote, but failed to secure an absolute majority. The SPD came in second with 20.5 percent of the vote. The CDU/CSU alliance's head Angela Merkel initially planned to form a coalition with the Greens and the Free Democratic Party, but the preliminary talks with them were unsuccessful. The SPD entered the talks with CDU/CSU after German President Frank-Walter Steinmeier's proposal, although initially, the party ruled out the possibility of forming a coalition with the Merkel-led alliance.
