Liechtenstein is a principality governed under a semi-constitutional monarchy. It has a form of mixed constitution in which political power is shared by the monarch and a democratically elected parliament. There is a two-party system (though there are two minor parties as well) and a form of representative democracy in which the prime minister and head of government is responsible to parliament. However, the Prince of Liechtenstein is head of state and exercises considerable political powers.
The executive power is exercised by the Cabinet of Liechtenstein (government). Legislative power is vested in both the government and the Landtag (Parliament). The party system is dominated by the conservative Progressive Citizens' Party and the liberal-conservative Patriotic Union. The judiciary is independent of the executive and the legislature.
