The next Senedd election is due to be held on or before 7 May 2026[1] to elect 96 members to the Senedd (Welsh Parliament; Welsh: Senedd Cymru). It will be the seventh devolved general election since the Senedd (formerly the National Assembly for Wales) was established in 1999. If held in 2026 it will also be the first election following current reforms to the voting system, which would increase the size of the Senedd from 60 members to 96, adopting a party-list voting system, reducing the number of constituencies to sixteen, and shortening its term from five years to four.[2][3] It will also be the second election since the Senedd changed its name in May 2020.

Electoral system
In all prior elections since its establishment as the Welsh Assembly in 1999, the Senedd has been elected through the additional member system, under which 40 out of 60 seats were elected by the first past the post system from single-member constituencies (the same as those used for Westminster), while the remaining 20 were attributed regionally (in 5 regions of 4 seats) on the basis of a second vote for a closed party list of candidates. The additional member seats in each region were allocated from the lists by the D'Hondt method, with constituency results being taken into account in the allocation.
Following the approval of the Senedd Reform Act, the size of the Senedd will be increased from 60 to 96 MSs, all elected through closed party list proportional representation (using the D'Hondt method). The elections will be organised in 16 six-member constituencies created by pairing up the 32 redrawn Westminster constituencies.[7][8]
Although the new system would only be ready and used for elections held after 6 April 2026, to allow time for the new constituencies to be drawn up.[9] The next election is due to be held on 7 May 2026.[10]
Another proposed reform bill would have provided for mandatory "zipping" of male and female candidates in the list to ensure that for every party, half of the Members will be women. However, this bill was scrapped in September 2024.[11]
