A leadership election was held to elect the next leader of Welsh Labour after First Minister Eluned Morgan failed to win her seat in Ceredigion Penfro in the 2026 Senedd election and resigned on 8 May 2026. This was the party's first leadership election since it lost control of the Senedd in May 2026, and therefore the new leader became the first not to be Welsh First Minister.

On 9 May 2026, Ken Skates was appointed as interim leader of Welsh Labour. On 15 July, Skates became the party's permanent leader after being appointed unopposed. He is the party's fourth leader in just over two years, after Morgan, Vaughan Gething and Mark Drakeford.

Procedure The Leader of Welsh Labour has to be a member of the Senedd. Candidates needed nominations from either 20 percent of the party's Senedd group (equating to two other members), ten percent of Labour MSs (one other member) and 20 percent of Constituency Labour Parties (equivalent to seven CLPs), or ten percent of MSs and three nominations from Welsh Labour affiliated organisations which must have included at least two affiliated trade unions.

The contest was initially scheduled to commence in September, but it was moved up on 8 July 2026. Welsh Labour MSs had a week from 9 July to declare who they supported. However, as all Labour MSs had supported interim leader Ken Skates, he was confirmed as the new leader on 15 July.
