In the Philippines, local government is divided into three levels: provinces and independent cities, component cities and municipalities, and barangays, all of which are collectively known as local government units (LGUs).
"[1][2] Local government units are under the oversight of the Department of the Interior and Local Government, which is an executive department tasked with assisting the president in exercising the power of general supervision.
In 2001, a plebiscite in the ARMM confirmed the previous composition of the autonomous region and added Basilan (except for the city of Isabela) and Marawi in Lanao del Sur.
Isabela City remains a part of the province of Basilan despite rejecting inclusion in the ARMM.
A Cordillera Autonomous Region has never been formed because two plebiscites, in 1990 and 1998, both resulted in just one province supporting autonomy; this led the Supreme Court ruling that autonomous regions should not be composed of just one province.
Municipalities are always a part of a province except for Pateros which was separated from Rizal to form Metro Manila.
Every city and municipality in the Philippines is divided into barangays, the smallest of the local government units.
The executive branch is composed of the Wali as the head of region and Chief Minister as the head of government for the Bangsamoro, governor for the provinces, mayor for the cities and municipalities, and the barangay captain for the barangays.
