Elections 2026 live: ‘I’m not going to walk away,’ says Starmer; Reform makes gains and Labour faces defeat in Wales and Scotland theguardian.com

Welsh Labour says it expects to be reduced to around 10 seats in the newly expanded Senedd after elections held on Thursday, a collapse from the 29 seats it held under the previous chamber. The Evening Standard reports the party conceded it would not lead the next Welsh government, while The Guardian’s live coverage described the result as an historic fall for a party that has dominated Welsh politics since devolution. The new Senedd has been expanded to 96 members and uses a more proportional voting system, changing how vote share translates into seats.

The raw number matters because it turns Wales from a Labour-managed subsystem into a competitive market for protest parties and regionalists. Reform UK and Plaid Cymru both performed strongly as results emerged, according to the Standard, with Reform’s leader in Wales, Dan Thomas, winning a seat in the Casnewydd Islwyn constituency and Plaid leader Rhun ap Iorwerth returning in Bangor Conwy Môn. Labour sources cited by the Standard said the party’s vote had “collapsed” in Blaenau Gwent Caerffili Rhymni — an area long treated as safe — to the point where it returned no Labour member.

The mechanics of the new system amplify punishment for a party that loses its core vote: when each of 16 constituencies returns six members, a party that slips from first to third can quickly go from a local monopoly to near-absence. Labour’s own statement, quoted by both outlets, tried to reframe survival as a platform: returning “around 10” members would at least allow a “vocal opposition”. That is the language of an organisation preparing to operate without the patronage that comes from running devolved government.

The Standard also links the Welsh rout to “disastrous” local election results in England overnight, where hundreds of Labour councillors were voted out and Prime Minister Keir Starmer said he took responsibility. In practice, devolved and local contests become a low-cost way for voters to send a message while keeping Westminster unchanged; the parties that benefit are those that can turn anger into a simple ballot choice without having to run the NHS or balance budgets. Reform’s gains and Plaid’s resilience suggest that the old two-party bargaining chip — ‘vote for us or you get them’ — is less effective when day-to-day governance is already experienced as decline.

Labour hinted that First Minister Baroness Eluned Morgan could lose her seat in Ceredigion Penfro, which would make her the first sitting Welsh first minister to do so. She was expected to speak at the count in Llandysul after the result was declared.

In Wales, Labour is no longer counting majorities. It is counting survivors.
