This is the form of a Union Government.
Step-by-step explanation:
The Union governmental system is one in which the central government has most of the power and sometimes it has all the administrative power and the regional blocs are there just for functions to be carried out.
This form of government is good for homogeneous regions that are also fairly small and the number of people in the nation is relatively less.
It is better to have a larger central government in that case as the people will still be adequately represented.
Thus, the people might chose this form.
