Welsh Labour has governed Wales continuously since the Senedd opened in 1999. The final YouGov Senedd MRP and a closing-week Ipsos Wales poll concur at roughly 12% of the vote, which would be Labour's lowest Welsh vote share since the 1906 general election 1. Eluned Morgan remains projected below the constituency threshold in Ceredigion Penfro. The £4 billion NHS investment programme Welsh Labour launched at the end of March has not moved the curve. The Wales Governance Centre's mid-April reading holds: voters did not switch parties on the manifesto; they realigned tactically inside an unfamiliar counting system.
The closing-week debate stage made the gap visible. BBC Wales's 'Your Voice Live' debate on Tuesday 28 April put all six leaders before Bethan Rhys Roberts in Cardiff . The Spectator's read was that Nigel Farage would be 'disappointed', with a Welsh net rating of minus 18 points (32% doing well against 50% doing badly) 2. Rhun ap Iorwerth held a positive net rating at plus 10. Morgan accused ap Iorwerth of 'crumbling under scrutiny' on net zero; ap Iorwerth quoted Reform UK Welsh policy chief Dan Thomas confirming Reform nationally wants to privatise the NHS, and Farage said Welsh Reform would not.
In January 1906 a Liberal landslide reduced the Conservatives to a single Welsh seat; Welsh Labour did not yet exist as a serious electoral force. The 12% projection is the lowest Welsh Labour vote share recorded, which means the comparator is the era before Labour was a national party. The defensive infrastructure built for FPTP devolved elections does not absorb the share into seat margins; the new closed-list PR system shows the collapse cleanly because it counts shares rather than wins.
The Welsh contest is now between a nationalist party and a hard-right party on Labour-built devolved infrastructure, with Labour supplying the coalition arithmetic from third place.
