The previous Welsh Government assessed the costs associated with the STV system being used by a principal council and published this in the Explanatory Memorandum to the Local Elections (Principal Areas) (Single Transferable Vote) (Wales) Rules 2023. This can be accessed via the Senedd website: EM SL(6)382 - The Local Elections (Principal Areas) (Single Transferable Vote) (Wales) Rules 2023.
