How is it unitary system of government different from a federal system in a unitary system all powers are held by one government in the unitary system most powers are reserved to provincial governments in a federal system there are no checks and balances between branches of government and the federal system the head of the executive branch and the legislative branch are the same person
I would like to correct some misconceptions in your description.
In a unitary system of government, powers are indeed held by one central government. The central government has authority over its subnational units, such as provinces or states, and can delegate powers to them. However, the central government may also retain certain powers for itself.
In a federal system, powers are divided between the central government and subnational units, which have their own powers and responsibilities. These subnational units, such as states or provinces, have their own governments and can exercise authority in areas within their jurisdiction. This division of power between the central government and subnational units is a key feature of federalism.
Checks and balances between branches of government exist in both unitary and federal systems. These checks and balances are mechanisms that ensure one branch of government does not become too powerful by limiting and balancing the powers of other branches. In a federal system, these checks and balances apply not only at the central level but also in the subnational units.
Regarding the executive and legislative branches, it can vary depending on the specific system. In a unitary system, the head of the executive branch and the legislative branch can be separate individuals (such as in parliamentary systems). In a federal system, they can be different individuals as well (such as in a presidential system), or they can be the same person (such as in a parliamentary federal system).
It is important to note that the specific characteristics and arrangements of unitary and federal systems can differ among countries and their constitutional frameworks.
