What are the merits and demerits of one party system?

The merits of a one-party system include political stability and efficiency in decision-making, as policies can be implemented without the gridlock often seen in multiparty systems. Additionally, it can foster a sense of national unity and purpose. However, the demerits include a lack of political pluralism, which can stifle dissent and limit individual freedoms. This often leads to authoritarian governance, where opposition is suppressed, and citizens may have little influence over political processes.
