The "Bundestag" is Germany's main legislative body. Its over 600 members are elected every four years in a mixed system of constituency and list voting.
All legislation has to pass first the Bundestag and then the Bundesrat, the upper house. The Bundestag is located in Berlin in the "Reichstag" building near the Brandenburg Gate.
Rules may be altered on who becomes "president by seniority" - a cherished role in Germany's lower chamber of parliament. Under present protocol, a founder of Germany's right-wing populist AfD could soon have the honor.
