The Brazilian government operates as a federal republic, consisting of three branches: the executive, legislative, and judicial. The President, elected for a four-year term, leads the executive branch and is responsible for implementing laws and managing the country. The National Congress, made up of the Chamber of Deputies and the Federal Senate, creates laws and oversees the executive. The judiciary is independent and interprets laws, ensuring justice in the country. Brazil's political system allows for multiple parties, promoting a diverse representation of views. Key issues often addressed by the government include economic development, social inequality, and environmental protection.
