Proportional representation is NOT necessary in a country where

1. Proportional representation (PR) is an electoral system designed to ensure that the share of seats won by a political party or group is proportional to the share of votes received. 2. PR systems are typically used in countries with multiple political parties to ensure fair representation for smaller parties. 3. In a country where a stable two-party system has developed, the need for PR diminishes. In such systems, one of the two major parties usually wins a majority or a significant plurality under simpler systems like the First-Past-The-Post (FPTP), and representation tends to consolidate around these two parties. 4. Reserved constituencies exist to ensure representation for specific groups, irrespective of the electoral system. 5. The First-Past-The-Post system often exists where PR is considered unnecessary, but FPTP itself doesn't make PR unnecessary; rather, the political landscape (like a two-party system) makes it less crucial. 6. Fusion of governmental forms doesn't directly negate the need for PR.
