What is meant by “Local Government”?

Local Government has been described as a political subdivision of a nation or state which is constituted by law and has substantial control of local affairs. In a unitary system of government, such as the government under the Philippine Constitution, local governments can only be an intra sovereign subdivision of one sovereign nation, it cannot be an imperium in imperio. Local government in such a system can only mean a measure of decentralization of the function of government.
