|Legislative power in the CR is invested in a bicameral Parliament, which is the sole and exclusive legislative body of the CR. The chambers have different system for electing members, and asymmetrical forms of political composition. In the Czech Republic the key institution directly legitimized by elections is the Parliament, while the legitimacy of the executive is derived from that of Parliament. However, the organs of executive power play an important formal and informal political role. The Czech executive is dualistic; the President of the Republic is the head of state; alongside is the government headed by its Premier, who is answerable to the Parliament. Until 2013 the President has been elected by the Parliament at a joint meeting of the both chambers, for a term of five years, with a two-term limit. From 2013 there will be changed the mode of election and the president will be elected directly. The decisive role within the executive branch in the Czech is played by the government. The position of the prime minister is formally and traditionally relatively strong. Within the judiciary branch there is an internal division of power between the Constitutional Court and regular jurisprudence. In the CR local government has two levels, regional and municipal. On both levels a mixed system of public administration is established, where together within the framework of a single institutional structure, both local self-government and to a certain extent regional self-government, as well as local state administration, are conducted. The role of political parties in the Czech political system is key. The Czech Republic is classified as a party-controlled parliamentarianism, in which the political parties play an important role in the process of forming and leading governments.
