Voting Systems Flashcards
How does FPTP work?
- one MP represents each constituency
- voter casts single vote of preferred candidate
- candidate with largest number of votes (seats) within a constituency is elected
How is FPTP disproportional?
winner doesn’t necessarily have to gain a majority of votes cast
party with the largest number of seats had the right to form government
Give an example of the party that won with less than 50% of the vote
Labour in 2005 won with 35%
Advantages of FPTP
- easy to use (little voter confusion)
- speedy and simple (no delay, elected members and governments are soon in place)
- usually produces clear outcomes (only been two coalitions since WW2)
- excludes extremist parties
- stronger link between MP and constituency
- smaller parties still receive some influence and power (2010 LibDem Conservative coalition)
Disadvantages of FPTP
- Winning candidate can win with less than 50% vote (Labour 2005 won with 35%)
- Forces voter to make a single vote (tactical voting more likely)
- Smaller parties do not have the chance to win
- Rarely produces clear winner
- Can lead to unstable, multi party constituencies
- Overrepresents two major parties
How does AV work?
- voters rank candidates in order of preference
- if no candidate reached more than 50% then candidates with lowest number of votes get eliminated
- votes are then redistributed to voters second choice
- continued until one candidate reaches 50%
When is AV used in the UK?
to elect conservative and labour leaders

How does STV work?
