According to Andrew Heywood, elections have three main functions. One of these functions is to “ensure representation”. However, it can be argued that some countries make this representation unrepresentative due to proportional electoral systems and lack of a majority. There are many electoral systems used around the world and each country seems to have adopted a particular system that works well for them but may not for others. Many countries tend to only use a few high systems, but the UK uses several! The different UK electoral systems are used for different purposes and this represents a large number and question of how proportional the UK is. If there is a need for different voting systems, everyone plans. As one of the main strengths of this electoral system is that the winning candidate must have more than half the support of the electorate, the additional vote takes effect if no candidate receives more than 50% of the vote. the vote, and was "promoted" to the second preference vote. Therefore, SV is a good thing because it requires more than half the support of the electorate and the people have two votes for more than one option. Additionally, due to the nature of the electoral system, fewer votes are lost, compared to the first past the post system. Once all votes are counted, votes win – all other votes are counted. With the OAS, once votes are counted, more votes are counted (depending on whether candidates have more than 50% of the vote, of course). This means that fewer visitors are ignored, which is why this system is very good. Additional vote - NegativeHowever, it is obvious that the SV is negative. The winner can't really get more first preference votes and may have simply won first place thanks to the extra majority vote. This therefore means that the winning candidate is not supported on the first choice, and therefore inferior to the result of a different electoral system. Therefore, small parties and extremist voters may have too much to say - perhaps even win - which would mean that proportionality is not
