The Senedd in Wales recently voted to support plans to increase its membership, following the report of a special committee, which endorsed proposals put forward by Labour and Plaid Cymru. Laura McAllister argues that the need to enlarge the Senedd is clear, but that proposed changes to the voting system are flawed and could undermine public support for reform.

That the Senedd marked its twenty-first ‘coming of age’ birthday by seeking to recast itself with a fundamentally altered institutional shape should surprise few familiar with devolved politics. Wales is often referred to as the land of commissions and inquiries. Each of these inquiries into the most ‘unsettled’ devolution settlement has recommended that the Senedd should increase from its current 60 Members (MSs) to a figure between 80 and 100. The story of these inquiries can be found on the Senedd website.

I chaired the Expert Panel on Assembly Electoral Reform in 2017, which was charged with looking at the size of the Senedd, its electoral system and extending the franchise to younger voters. Our Panel’s recommendations were that:

• The number of members should be increased from 60 to at least 80, and preferably closer to 90. We concluded that this was needed because the Assembly (its name was changed to ‘Senedd Cymru/Welsh Parliament’ in 2020) had acquired a much greater role than the one it had in 1999, and also that its powers were expected to expand further. We concluded that the Senedd could not be expected to continue functioning optimally and delivering for the people of Wales if it remained at its current size.

• That a new electoral system should be introduced to accommodate this increased size and to make the relationship between votes cast and seats won more proportional. Our favoured system was Single Transferable Vote (STV) accompanied by prescriptive, legislative gender quotas, though the Panel also regarded a Flexible List system of proportional representation (PR) as a viable alternative.

• That the minimum voting age in Senedd elections should be reduced to 16 as a means of boosting democratic participation.  We regarded it as essential that the lowering of the voting age should be accompanied by high-quality education about politics in schools and other places of learning. This last recommendation was enacted through the Senedd and Elections (Wales) Act 2020 and came into force for the 2021 Senedd elections.

There was deemed insufficient political consensus to advance our first two recommendations around size and electoral system change in time for the 2021 election, despite a report from the Senedd Committee on Electoral Reform chaired by Labour MS Dawn Bowden, which almost exactly replicated our report’s recommendations. This committee did acknowledge that time had effectively run out and instead called for legislation early in the Sixth Senedd to increase its size to between 80 and 90 Members from the 2026 election, with all MSs elected by STV.
