The Sénat is the upper house of the French Parliament, responsible for representing local governments and ensuring that laws reflect the interests of all regions. It consists of senators who are elected for six-year terms, with half of the seats renewed every three years. The Sénat plays a crucial role in the legislative process, reviewing and amending proposed laws passed by the lower house, the Assemblée Nationale. It also has the power to initiate legislation and participate in discussions about national policies, making it an essential part of France's democratic system.
