Different types of voting systems in the UK
additional member system
it is used in the london assembely, the welsh sennedd and the scottish parliament
it is a hybrid between majoritarian and PR
they have two votes, they have a vote for their constituency, and then there is the regional list vote which is used to make results more proportional
creates a more proportional outcome than FPTP it also leads to coalition and minority governments, it maintains consituency representation
4/5
First past the post
it is used for general elections in the UK and is one of the best known systems of voting
it is a majoritarian system in nature
first past the post works by setting a goal of seats that a party must reach first before anyone else, the fastest party to receive the number of seats required is then invited to form a parliament, this can lead to high and very large majorities even if there are low voter turnouts
it can lead to massive majorities in parliament even if there is low voter turnout
rating 3/5
Supplementary vote
It is used to elect london commissioners
it is a majoritarian two round hybrid
voters have two choices, first and second preference, if a candidate wins more than 50% then they win by default, if not one gets over half then the least voted is kicked until there is one who reaches the mark
encourages candidates for wide support and reaching out, still not proportional
3/5
single transferable vote
Used for Northern Ireland Assembly, local elections in Scotland, and European elections in Northern Ireland (when the UK was in the EU).
Proportional representaition
voters will rank the candidates in order of how much they like them going from 1 downwards, a quota is made and those who reach it will pass through to the next stage until there is a winner
it produced proportional outcomes, few wasted votes, allows voter choice between and within parties
