Each one with the model answer underneath.
- 1
Describe how the Additional Member System works.
Model answer
Voters cast two votes, one for a constituency member elected by plurality and one for a party list, and list seats are then allocated to correct the constituency result.
- 2
How many members did the Senedd have, and how were they elected, under the Additional Member System?
Model answer
It had 60 members: 40 elected in single-member constituencies by plurality and 20 elected from five regional lists of four members each.
- 3
Are the regional lists used for the Senedd open or closed?
Model answer
They are closed lists, so the party fixes the order of its candidates and voters choose only between parties.
- 4
Which formula allocated the Senedd's regional seats, and how did it take account of constituencies already won?
Model answer
The d'Hondt formula was used, dividing a party's regional vote by the number of seats it already held in that region plus one, then reallocating after each seat.
- 5
Why is the Additional Member System called a hybrid system?

It combines a plurality element in single-member constituencies with a proportional list element in larger regions.
- 6
What is a top-up seat?
Model answer
A top-up seat is a list seat awarded to compensate a party whose constituency seats fall short of its share of the vote.
