Weakness of unitary..

1. Lack of local autonomy: In a unitary system, decision-making power is centralized with the national government, leaving little room for local governments to make their own decisions. This can result in the neglect of local needs and preferences.

2. Lack of accountability: Because power is concentrated in the hands of a single government entity, there may be less checks and balances in place to hold leaders accountable for their actions. This can lead to corruption and misuse of power.

3. Difficulty in representing diverse populations: Unitary systems may struggle to adequately represent and address the needs of diverse regions or populations within the country. This can lead to social unrest and tension between different groups.

4. Inefficiency: Centralized decision-making can lead to bureaucratic inefficiencies, as decisions may take longer to be made and implemented. This can hinder the government's ability to respond quickly to changing circumstances.

5. Vulnerability to authoritarianism: Unitary systems can be susceptible to authoritarianism, as the concentration of power in the hands of the national government can enable the suppression of dissent and political opposition. This can lead to human rights abuses and lack of political freedom.
