Elections And Referendums: The Main Electoral Systems Used in The UK, And Their Advantages And Disadvantages Flashcards
What are the electoral systems used in the UK?
First-Past-The-Post (FPTP): used in general election and English local elections
Party list proportional (List PR) or D’Hondt system: used in European Elections
Additional member system (AMS): used in Scottish and Welsh parliaments
Single transferable vote (STV): used in Northern Ireland Assembly and Scottish local council elections
Alternative vote (AV): used in the elections of parliamentary select committee chairs
What are the key details that would occur if every electoral system sued in the UK was used for the 2019 general election?
Only FPTP would have produced a government with an overall Commons majority
The Conservatives and SNP would gain fewer MPs using alternative voting systems
The Lib Dems would benefit the most from electoral reform
The smaller parties would fare best under AMS compared with other alternative electoral systems
How does FPTP work?
Works on the majoritarian principle that the candidate with the largest number of votes in each constituency wins the seats, those who are runners up receive nothing, its a winner takes all mentality
How does List PR work?
Instead of electing one person per constituency as with FPTP, in List PR system each area is bigger, electing a group of MPs that more closely reflects the way the area voted, so instead of 650 individual constituencies with 1 MP, it might be 26 large constituencies with 25 MPs
How did the List PR system elect MPs in the UK European Parliament elections?
At the start of each round, the total votes for each party received at the start of the process are divided by the number of seats the party has already won, plus one, and the party with the highest remaining total wins the seat at that round
How does AMS work?
Voters have two ballot papers and two votes, the first is a list of candidates standing to be the constituency representative, the second is a list of part standing in that region, with the first ballot being a ‘winner takes all’ basis while the second regional list ballot are counted and the overall share of the vote is calculated, if a party wins few constituency seats than its overall share entitles it to, the ‘extra’ is made up from seats allocated to the second ballot, making the regional list a ‘top up’ of underrepresentation from the constituency results
What is AMS a hybrid system between?
A mixture of FPTP and List PR
Where is AMS used in the UK?
Scottish and Welsh parliaments and the London Assembly
Where is STV currently used?
European elections in Northern Ireland and Scottish local council elections
How does STV work?
Multi-member constituencies where voters rank their choices in order of preference, a quota is worked out based on the number of seats and the total number of votes cast, a candidate who has more first preference votes than the quota is immediately elected, surplus votes are transferred to other candidates in proportion to the second preference marked on the ballots received by that candidate, if more candidates than seats remain, the candidates with the fewest votes is eliminated, their votes are transferred to other candidates as determined by the voters second preference
What is AV?
Alternative vote
How does AV work?
The voter adds a number by the name for each candidate, with one for their favourite and so on, if a candidate receives more than half the votes in the first stage that candidate us elected, if nobody gets half, whichever candidate came last is elicited and their second preference votes are redistributed, the process is repeated until one candidate gets at least half the vote
What does AV ensure in a candidate?
that the winning MP has the support of the majority of voters
How can we analysis FPTP evaluating it with its proportionality and a fair result?
The number of seats does not directly reflected the proportion of votes cast for each part, it tends to exaggerate the performance of the winning party plodding a ‘winner’s bonus’
How can we analysis List PR evaluating it with its proportionality and a fair result?
List PR are very copse and reflects actual vote share of the parties
How can we analysis AMS evaluating it with its proportionality and a fair result?
As its a hybrid system between FPTP and List Pr, it results in a fair result and is largely proportionate
