The Polish government operates as a parliamentary republic, where the President serves as the head of state and the Prime Minister is the head of government. The government is divided into three branches: the executive, legislative, and judicial. The Sejm and Senate make up the legislative branch, responsible for creating laws. Elections in Poland are held every four years, allowing citizens to vote for their representatives. The Constitution of 1997 outlines the structure and functions of the government, ensuring the protection of civil rights and the rule of law. The government also plays a role in international relations, particularly within the European Union.
