In a federal state, power is shared between the central government and the other co-ordinate units, which are typically local authorities or regional governments. This means that there are two levels of government, each with its own specific powers and responsibilities.
The central government has the authority to make laws and policies that apply to the entire country, while the local authorities or regional governments have their own laws and policies that apply to their specific areas. These co-ordinate units have a degree of autonomy from the central government, which allows them to make decisions that are in the best interests of their citizens.
This system of government is designed to provide a balance of power between the central government and the other co-ordinate units, ensuring that no level of government becomes too powerful and that the needs and interests of all citizens are represented. Therefore, power is shared between the central government and the other co-ordinate units, rather than among the major regions of the federation or the country as a whole.
