In general elections for the Senedd, each voter had two votes. The first vote was used to vote for a candidate to become the Member of the Senedd for the voter's constituency, elected by the first past the post system. The second vote was used to vote for a regional closed party list of candidates. Additional member seats were allocated from the lists by the d'Hondt method, with constituency results being taken into account in the allocation. ==Assembly members and Members of the Senedd==
