The Additional Member System, STV and Other Systems
- 3 things to know
- Paper 1
Overview
Recall questions on the additional member system in Scotland, the single transferable vote in Northern Ireland, the supplementary vote, closed lists and the alternative vote, and how each electoral system shapes the party system.
What you need to know
Answer each one before you reveal it.
Is the additional member system fully proportional? Justify your answer.
Which system is used for Scottish local elections?
Questions from this subtopic
Each one with the model answer underneath.
- 1
What system is used to elect the Scottish Parliament?
Model answer
The additional member system, a hybrid combining constituency members elected by first-past-the-post with regional members allocated from party lists.
- 2
How many members does the Scottish Parliament have, and how are they divided?
Model answer
It has 129 members: 73 elected in single-member constituencies and 56 elected from eight regional lists.
- 3
Explain how the regional top-up works under the additional member system.
Model answer
Regional list seats are allocated so as to compensate parties that won fewer constituency seats than their regional vote share warranted, which pulls the overall result closer to proportionality.
- 4
Give two advantages of the additional member system.
Model answer
It produces a broadly proportional overall result while preserving a constituency representative for each area, and it allows voters to split their support between a local candidate and a different party.
- 5
Give two criticisms of the additional member system.
Model answer
It creates two classes of representative with different mandates, and the regional lists are closed, so parties rather than voters decide the order in which list candidates are elected.
- 6
Is the additional member system fully proportional? Justify your answer.
Model answer
No; the constituency element still favours larger parties, which is why the SNP was able to win an overall Scottish Parliament majority in 2011 on well under half the vote.
