Labour Faces Major Test in UK Elections Across England, Scotland, Wales

Labour faced a sweeping electoral test on Thursday as voters across England, Scotland and Wales cast ballots that could reshape power in Cardiff, Edinburgh and dozens of English town halls, and deliver the first major verdict on Keir Starmer since Labour returned to government in 2024.

In England, 4,851 council seats across 134 local authorities were on the line, along with six directly elected mayors. That makes the local contest the clearest barometer of Starmer’s standing, because it shows how Labour is performing outside Westminster and whether discontent is spreading beyond a routine mid-cycle protest. Pollsters have warned that Labour could suffer its worst-ever showing in English local elections, with losses that could exceed 1,000 seats and gains for Reform UK, the Greens and the Liberal Democrats.

Wales posed the sharpest strategic threat. Labour has led every Welsh government since devolution began in 1999, but final polling suggested it could lose control of the Senedd for the first time after 27 years in power. Some forecasts put Labour on about 12 seats, well behind Plaid Cymru and Reform UK under the new proportional system that will elect 96 members. Welsh Labour leader Eluned Morgan said Starmer “is an issue on the doorstep” and could cost the party the Senedd, underscoring how national dissatisfaction was bleeding into Welsh voting intentions.

Scotland was also expected to be punishing for Labour. The Holyrood election was being watched as a test for Scottish Labour leader Anas Sarwar as well as Starmer, with projections suggesting Labour could fall well behind the Scottish National Party. Labour figures in Scotland have not ruled out leadership pressure if the party performs badly, a sign that the stakes extend beyond one night’s seat count.

Financial markets were watching too. Investors were concerned that a weak Labour result could intensify leadership pressure on Starmer and renew fears over fiscal discipline, turning local and devolved ballots into a broader judgment on economic credibility.

What would count as a warning sign is clear: heavy English losses, a collapse in Wales and a strong SNP lead in Scotland. A routine protest vote would hurt Labour, but it would still leave Starmer intact. If Labour is pushed out of first place in Wales and suffers deep losses in England, this vote will have gone far beyond local politics.
