The main role of the governor is to oversee the implementation of decisions by government ministries, constitutional requirements and legislation passed by Grand National Assembly within the provincial borders.

As the commander of the provincial police and Gendarmerie forces, the governor can also take decisions designed to limit civil disobedience and preserve public order.
