Ireland is going to the polls later this year, highlighting its Single Transferable Vote system which could be used to elect Members of the Scottish Parliament.

STV is a preferential system where voters rank candidates in order or preference in multi-member constituencies. The system is already used to elect Scottish councillors, as well as various electoral chambers in Northern Ireland, Malta and Australia, and can have better outcomes than Holyrood’s Additional System when it comes to voter choice and proportionality (depending on the exact parameters of the STV system used).

The system has been used in the Republic of Ireland since the country’s independence from the United Kingdom. Two attempts have been made to revert to First Past the Post, however, the people of Ireland voted against these in referendums in 1958 and 1968, ensuring the continued use of STV to this day. The upcoming election shows an alternative future to Westminster’s First Past the Post and Holyrood’s broadly proportional, albeit flawed, Additional Member System.

Will 2031 be the first Scottish election to use STV?

Wales is changing its voting system. Why not Scotland? 2026 will be the first Welsh election not held under AMS. instead MSs will be elected via the more proportional, but less voter empowering, Closed List PR system.

The current Scottish Government has no plans to ditch AMS, meaning a change ahead of 2026 elections is unlikely. But change might be possible next parliament as political winds shift. Two-thirds of MSPs would have to support reform for a change in voting system to be enacted.

Ireland offers an alternative the Scotland’s Additional Member System, however, the Irish system isn’t perfect as constituency sizes range from three to five members, limiting overall proportionality. A Scottish system should account for this and introduce larger multi-member constituencies, similar to Northern Ireland instead.

STV offers an opportunity to strengthen Holyrood’s representation. The next election offers Scotland an opportunity learn from our neighbours and to seize reform.
