The Senedd voted 40-12 on 24 September 2024 to withdraw the bill that would have forced parties to alternate men and women on their closed lists. The 96-seat chamber now enters its first PR election with no legal floor on women's representation.

Key takeaway

Wales enters PR with no legal gender floor because the bill designed to provide one was withdrawn in 2024.

The Senedd voted 40-12 on 24 September 2024 to withdraw the Senedd Cymru (Electoral Candidate Lists) Bill, scrapping the statutory gender-zipping rule thirteen months before nominations opened for the first election under closed-list PR. The Welsh Government had sponsored the bill as a balanced-representation companion to the wider PR Reform. Its replacement is non-binding guidance, with no mechanism to force compliance if parties rank men above women on their constituency lists.

The withdrawal broke the prospectus on which the Wales Governance Centre and the Electoral Reform Society had campaigned. Both institutions had treated the zip as an inseparable element of the 96-seat expansion. The justification Welsh ministers gave in 2024 cited cross-party legal concerns about compatibility with the Equality Act 2010 and wider UK electoral law, though no court ruling was ever sought to test the proposition.

Under closed-list PR, parties publish a ranked slate; voters choose a party, not a candidate, and the D'Hondt method awards seats in list order. List ordering is a private internal decision at each party. If a party ranks male incumbents at positions 1-3 in a six-member constituency, the arithmetic of the threshold ensures those men win before any woman on the slate is reached. The new 96-seat chamber could therefore return fewer women than the outgoing 60-seat Senedd.

Deep Analysis

In plain English

Wales is electing a bigger parliament on 7 May — 96 seats instead of 60 — under a brand new system where you vote for a party, not a person. Under the old system, you got two votes: one for a local candidate, one for a regional party list. Under the new system, parties rank their own candidates internally, and seats go to whoever the party has put at the top of its list in each area. The Welsh Parliament had been debating a rule that would have forced parties to alternate men and women on those ranked lists — so position one would be a woman, position two a man, and so on. That rule was scrapped by a 40-12 vote in September 2024. There is now no legal requirement for any particular gender balance. Which women — and how many — reach Cardiff depends entirely on what order each party decided to put its candidates in.

Deep Analysis

Root Causes

The withdrawal reflects a structural tension within Welsh devolution between the Senedd's ambition to legislate on equal representation and the constitutional boundaries of what the Senedd can legislate without conflicting with reserved Westminster law.

The Equality Act 2010 is a reserved matter. The Welsh Government's stated concern about compatibility was not tested in court, but legal uncertainty at a late stage of a legislative term creates a credible incentive to withdraw rather than challenge.

The timing is also a product of the broader electoral reform timetable. The shift from AMS to closed-list PR was agreed late in the Sixth Senedd term, compressing the window for companion legislation. The gender-zipping bill was drafted and introduced in the same compressed period, giving it less scrutiny time than a structural electoral change of that magnitude would normally receive.

What could happen next?

Risk
The 96-seat Senedd may return fewer women than the outgoing 60-seat chamber if parties rank male incumbents at winnable list positions.
Immediate · 0.72
Precedent
Wales becomes the first UK legislature to use closed-list PR without any statutory gender floor, making the 2026 result a live test of voluntary guidance efficacy.
Medium term · 0.85
Consequence
If women's representation falls, pressure will mount in the 2026-2031 term for statutory intervention, potentially reopening the Equality Act compatibility question in a UK Supreme Court context.

Source Landscape

This story draws on neutral-leaning sources

Primary parallel: Scotland's first Holyrood election in 1999 used AMS without a statutory gender quota but with voluntary twinning arrangements by Labour and the SNP. It returned 37 per cent women — a UK record at the time — demonstrating that voluntary party action can substitute for statute when parties choose to prioritise it.

Counter-parallel: The 2019 Welsh Assembly (as it then was) returned 47 per cent women under AMS with no statutory floor, the highest of any UK legislature. The move to closed-list PR with voluntary guidance alone risks that figure falling, not rising, if parties rank male incumbents first.

Consensus view: The Wales Governance Centre (Cardiff University) and the Electoral Reform Society both argued that closed-list PR without a statutory gender floor transfers representational power entirely to party selection committees, removing any public accountability mechanism for the gender composition of the new 96-seat chamber.

Counter-view: The Institute of Welsh Affairs noted that non-binding guidance may prove more durable than a statutory zip if parties internalise it voluntarily, and that the Equality Act 2010 compatibility question raised by the Welsh Government was a genuine legal risk rather than a pretext.

Key tension: Whether closed-list PR in Wales will in practice produce better or worse gender balance than AMS did, since the evidence from comparable European PR systems is mixed.

Different Perspectives

Local Government Association

New chair Eamonn O'Brien broke the LGA's neutrality on reorganisation for the first time since December 2024, telling the incoming prime minister the 'unprecedented scale' of disaggregation risks statutory services and asking him to adjust the LGR timetable, aligning the sector's institutional voice with the judicial review claims Suffolk, Essex and Norfolk have already filed.

Reform UK

Reform's £12m Harborne windfall from 2025 predates the 25 March retrospective crypto-donation ban, so the new law does not reach it; a live police probe into £500,000 of Cottrell donations continues, while the standards inquiry into Harborne's undeclared £5m gift is frozen since Farage vacated Clacton on 8 July.

Incoming Burnham government

Burnham secured 349 of the backing the NEC's 81-MP threshold required by 13 July, becoming Labour leader on 17 July and prime minister on 20 July without a members' ballot. He now inherits the LGR timetable the LGA wants him to adjust and a finance bill his own backbencher, Liam Byrne, is trying to harden further via amendment NC34.

Rupert Lowe / Restore Britain

Lowe called Farage's Clacton contest a 'Reform-sponsored media circus' and kept Restore Britain out of it, pledging instead to stand in the second by-election he expects the Harborne inquiry to force later this year. The boycott doubles as a signal that Restore Britain, not Reform, will contest the 'real' vote.

Kemi Badenoch / Conservative Party

Badenoch dismissed Farage's Clacton contest as a 'fake by-election' and joined the boycott, but reserved the right to fight a genuine second contest if Greenberg's inquiry forces one. The Conservatives are betting their real fight comes in autumn, not July.

Rhun ap Iorwerth / Plaid Cymru

Ap Iorwerth defended a £145m NHS allocation at First Minister's Questions on 1 July, blaming a graduate-nurse shortfall on 2022 training decisions taken before his Plaid-led government took office in May. Answering for choices his government did not make gives his new administration its first real accountability test.
