The politics of Austria take place in a framework of a federal parliamentary representative democratic republic, with a Federal Chancellor as the head of government, and a Federal President as head of state. Governments, both local and federal, exercise executive power. Federal legislative power is vested both in the government and in the two chambers of parliament, the National Council and the Federal Council. Since 1949 the conservative Austrian People's Party (ÖVP) and the center-left Social Democratic Party of Austria (SPÖ) have largely dominated the party-political landscape of Austria.
