The UK is one of the few examples in Europe that uses FPTP as an electoral system and it has heavily been criticised by the scholars about the lack of representativeness of such system. The 2010 General elections have triggered the debate on the level of representativeness when Liberal Democrats could not obtain the expected number of seats when compared to the vote they have won. The 2015 General election have resulted in the traditional way of having two parties dominating the parliament, but this time UKIP obtained 12% but only 1 seat, which is an example of disproportionality.This paper also calculates the possible outcome of 2015 elections if the UK was using PR as a system. Then the comparison between the two systems are conducted by using diagrams and concrete number of seats under each system. In the end, comparison of each system on the basis of representativeness is discussed with the help of the vote/seat relation.Show less
