Electoral system
The electoral system used is additional member system:
- There are 14 first-part-the-post territorial constituencies.[1]
- There is a single electoral region electing a fixed number 11 additional members elected from a party list;[1] seats allocated using d'Hondt method, in order;[1][2] any party gaining less than 5% of the vote is not eligible for an additional member seat.[2]
- There are no levelling seats.[3]
