The president, currently Frank-Walter Steinmeier, is the head of state and invested primarily with representative responsibilities and powers. He is elected by the Bundesversammlung (federal convention), an institution consisting of the members of the Bundestag and an equal number of state delegates

Since 1949, the party system has been dominated by the Christian Democratic Union and the Social Democratic Party of Germany. So far every chancellor has been a member of one of these parties. However, the smaller liberal Free Democratic Party and the Alliance '90/The Greens have also been junior partners in coalition governments. Since 2007, the left-wing populist party The Left has been a staple in the German Bundestag, though they have never been part of the federal government. In the 2017 German federal election, the right-wing populist Alternative for Germany gained enough votes to attain representation in the parliament for the first time.[127][128]
