A Unitary government IS the national government. A Unitary governmental system describes a Nation-State that consolidates all political authority in the national government.
An example of a Unitary government is the parliament/prime minister of England.
The national government holds all the power in a unitary government, as opposed to a federal systems as seen in the United States where power is fragmented between the federal, state and local levels.
A unitary state is a system of government where most or all of the governing power is held by a single, central government authority. This centralized government typically delegates limited powers to lower levels of government such as states or provinces, but retains the ultimate authority. Examples of unitary states include France and Japan.
In a unitary government system, the central government holds most, if not all, of the power. Local or regional governments derive authority from the central government and can be created, abolished, or reorganized by it. This system promotes uniform laws and policies across the entire country.
By definition, a unitary state is one in which significant and subordinate levels of government, as in federal states, do not exist, so power can either only be concentrated at the central level or via powers given from that government to departments or municipalities.
According to the Norwegian political scientist Xyvind Xsterud, the difference between a unitary and a federal state is not that one is more decentralized than the other, but that the former is decentralized through legislation whereas the latter is decentralized by constitution. In a federation, certain matters are thus constitutionally devolved to local units, and the central government cannot unilaterally revoke this decentralization, as it can in a unitary state.

Central government
A unitary system is a set of components for political organizations where most of the governing power resides in a centralized government. An unlimited government can be carried out by a group of people so a unitary system is possible.
A system of government not defined by a geographic distribution of power is a unitary system. In a unitary system, power is centralized in a single national government, which holds the authority to create or dissolve local governments. This contrasts with federal systems, where power is divided between national and regional authorities. In a unitary system, local governments primarily execute the directives of the central authority rather than having autonomous powers.
A Unitary Government is a government where the power is held by one central authority. This happens a lot in a dictatorship, but some democracies also have them, like Great Britain. Unitary government: a system of government where there is a single system of administration, law, money, and measurement.
A unitary government is not defined by a geographic distribution of power. In a unitary system, power is concentrated at the national level, and local governments have limited authority that can be changed or revoked by the central government.
National
The Federation of Russia has a federal system of government because the national government holds power but sub national governments also have powers that cannot be taken away from them. The Russian Federation consists of 83 sub national governments. The Federation of Russia though it is a Federal system does have a strong centralized government with lots of power given to the president.
Federalism is a system of government in which the national government and state governments share governmental power within the same political system, which have jurisdiction over individuals. Unitary system of government is one in which, principle power within the political system lies at the level of a national or central government, which individual citizens have direct allegiance to the national or central government and possesses ultimate power to make all political choices and determine public policy.
A unitary system of government is a type of government where power is centralized. When power is shared between a central government and local governments, this is referred to as a federal system of government.
it prevents a single national government from holding all of country's power.
