What are the changes to the voting system in 2026?
The Senedd website contains a bank of useful information explaining the voting system changes – please access this for full details. A short summary is included below:
There are now six seats per Senedd constituency and Merthyr Tydfil is part of the newly created Pontypridd Cynon Merthyr constituency.
The Returning Officer for Rhondda Cynon Taf is responsible for the administration of the constituency. Find out more about Voting and Elections on the Rhondda Cynon Taf Council website.
There has been a change from the ‘First Past the Post’ voting system to what is called a ‘Closed Proportional List’ system.
This will see political parties listing up to eight candidates each, and they will be listed on the ballot paper alongside the individual Independent candidates.
Each voter will get one vote, for a political party or an Independent candidate.
Candidates elected to the Senedd will be calculated using the D’Hondt method, based on the total number of votes each party receives. It uses a process of highest averages to distribute seats one-by-one until all seats are filled.
