Electoral systemEdit

In elections for the National Assembly for Wales, each voter has two votes in the additional member system. The first vote is for a candidate to become the Assembly Member for the voter's constituency, elected by the first past the post system. The second vote is for a regional closed party list of candidates. Additional member seats are allocated from the lists by the D'Hondt method, with constituency results being taken into account in the allocation. The overall result is approximately proportional.

In accordance to the Wales Act 2014, a candidate is allowed to stand in both a constituency, as well as a regional list. However, holding a dual mandate with the House of Commons is illegal, meaning an Assembly Member cannot also be an MP.

Retiring AMsEdit

The following, previously incumbent AMs, will not run for re-election:

Constituency/Region Departing AM Party
Bridgend Carwyn Jones [2] Welsh Labour Party
