Members of the Senedd, also known as Members of the Senedd (MSs), are elected representatives in Wales who serve in the Welsh Parliament. They are responsible for making laws, scrutinizing the government, and representing the interests of their constituents. Each MS is elected through a mixed system that includes both first-past-the-post and proportional representation. The Senedd has powers over various areas, including health, education, and the environment, allowing MSs to address local and national issues effectively.
