The Mexican federal government operates as a constitutional republic, consisting of three branches: the executive, legislative, and judicial. The President of Mexico serves as both the head of state and government, overseeing the administration and enforcing laws. The legislative branch is bicameral, comprising the Chamber of Deputies and the Senate, which create and amend laws. The judicial branch interprets laws and ensures justice, with the Supreme Court of Justice being the highest court. The federal government is responsible for national policies, security, and international relations, while also coordinating with state and local governments to address regional issues.
