Answer:
This nation would be a Unitary Government.
Explanation:
The unitary government is the one that has a single source of power. In this government, the single central government heads over the local bodies.
Further administrative divisions are made by the central government that execute only those powers that have been delegated to them by the central government. It is a perfect example of exercising authority over all departments. An example of a Unitary Government is the one in Northern Ireland and the UK.
