query: Who rules Germany?
passage: President of Germany
Germany has a parliamentary system of government in which the chancellor is the nation's leading political figure and de facto chief executive. The president has a mainly ceremonial role, but he can give direction to general political and societal debates and has some important "reserve powers" in case of political instability (such as those provided for by Article 81 of the Basic Law).[2] The German presidents have wide discretion about how they exercise their official duties.[3]
passage: Basic Law for the Federal Republic of Germany
The Chancellor is the head of government and the most influential figure in German day-to-day politics, as well as the head of the Federal Cabinet, consisting of ministers appointed by the Federal President on the Chancellor's suggestion. While every minister governs his or her department autonomously, the Chancellor may issue overriding policy guidelines. The Chancellor is elected for a full term of the Bundestag and can only be dismissed by parliament electing a successor in a "constructive vote of no confidence".
