Its major drawback is that the counting and allocation process is not simple.
Explanation:Under proportional representation, accurate vote counting is essential to divide seats fairly.
This involves complex calculations to match votes to seats.
Electoral officers must follow many rules and adjust figures repeatedly.
The process can become slow and burdensome, sometimes causing delays in announcing results.
