The provinces are subdivided into 59 districts and 1,200 wards (sometimes referred to as municipalities). Each district is headed by a District Administrator, appointed by the Public Service Commission. There is also a Rural District Council, which appoints a chief executive officer. The Rural District Council is composed of elected ward councillors, the District Administrator and one representative of the chiefs (traditional leaders appointed under customary law) in the district. Other government functions at district level are carried out by district offices of national government departments.
