Brazil is a federal presidential constitutional republic, based on representative democracy. The federal government has three independent branches: executive, legislative, and judicial. Executive power is exercised by the executive branch, headed by the President, advised by a Cabinet.
As stressed above, Brazil has a multiparty political system, with full freedom affiliation. We live in what some social science analysts call of Coalition Democracy, where no party can gain power alone, they have to create alliances in order to stand for the elections and govern.
