- Proportional Representation (PR) electoral systems aim to allocate seats in proportion to the votes received by parties. They are designed to ensure fair representation for minority parties and often lead to coalition governments, especially in multi-party systems. - In contrast, the first-past-the- post (FPTP) system, common in countries with strong two-party systems (like the UK or the US), tends to produce clear winners and majority governments by allocating seats to the candidate with the most votes in each constituency. - In a stable two- party system, FPTP often provides decisive election outcomes and stable governance, making the proportional allocation of seats provided by PR less critical for forming a government or representing a fragmented political landscape.
