The Additional Member System (AMS) is a voting method used... Show more

The Additional Member System splits representation into two parts. In the first vote, Scotland is divided into 73 constituency seats elected using First Past the Post, creating a direct link between constituents and their local MSP. The second vote divides Scotland into 8 regions, with regional MSPs elected via a Party List System using a formula that aims to make the overall result more proportional.
One of the greatest strengths of AMS is that it creates clear representation for voters. Each citizen has a directly elected local MSP they can approach with concerns or issues. For example, when Siobhan Brown narrowly defeated John Scott by just 200 votes in the 2021 Ayr constituency election, residents gained a representative they had specifically chosen, strengthening the democratic connection.
However, AMS can sometimes create confusion about representation. Since each voter is represented by 8 different MSPs (1 constituency MSP and 7 regional MSPs), it can be unclear which representative to approach. In places like Prestwick, having 2 SNP, 3 Conservative and 2 Labour MSPs might leave constituents uncertain about who to contact with their concerns.
Think about it: While having multiple representatives gives voters more options, it also creates a potential communication challenge. How would you decide which MSP to approach with a local issue?
AMS significantly increases voter power by providing two separate votes. Even if your preferred candidate doesn't win the constituency seat, your regional vote still contributes to your party gaining regional representation. This means more voters see their preferences reflected in parliament, encouraging continued participation in the democratic process.

The dual-vote nature of AMS means voters rarely "waste" their votes. For example, a Labour supporter in Ayr might be disappointed when the SNP wins the constituency seat, but their regional vote could still help secure Labour regional MSPs. This creates a system where more voters feel their voice matters, strengthening democratic engagement.
However, AMS does shift some power to political parties, particularly with regional lists. Parties decide which candidates appear on regional lists and in what order, meaning voters choose a party rather than specific individuals. When an MSP resigns, as happened when Kezia Dugdale quit as an MSP, the party decides the replacement without voter input, potentially weakening the democratic connection.
A significant strength of AMS is how it strengthens parliamentary oversight. Since it's rare for any single party to achieve a majority under this system, governments typically need to form coalitions or agreements with other parties. For instance, the SNP has previously made deals with both the Green Party and Conservatives to pass budgets, ensuring more diverse perspectives influence legislation.
The flip side is that AMS can sometimes lead to smaller parties wielding disproportionate influence. When a government needs support from minor parties to pass legislation, these smaller groups gain significant leverage. In 2016, the Green Party won just 5% of the vote but gained substantial influence over SNP decisions despite the SNP winning around 50% of the vote.
Important insight: AMS creates a balance between having a strong government and ensuring diverse representation. This trade-off is central to understanding whether you believe AMS is an effective voting system.
Overall, despite some drawbacks like potential government instability and increased party power, AMS delivers significant benefits through clearer representation, increased voter empowerment, and stronger parliamentary oversight, making it generally an effective voting system for Scotland.
