The Labour Party, led by Prime Minister Keir Starmer, is facing challenges in the council elections in England and the Assembly elections in Scotland and Wales. Over 5,000 seats in 136 councils of England are up for grabs, with the Labour Party defending 2,566 seats and the Conservatives on 1,364 seats.

The party is projected to lose as many as 1,900 seats, or three quarters of its current tally, according to University of Oxford's Stephen Fisher. The Conservatives, who suffered big losses in the 2024 general election, could lose 1,010 seats.

In Scotland, all 129 places in the Scottish Assembly at Holyrood were contested, with voters animated by issues around the cost of living, health and social care, and immigration. The Scottish National Party (SNP) is projected to win 62 seats, with Reform coming in second with 19 seats and Scottish Labour following closely behind in third place with 17 seats.

In Wales, the Senedd (Assembly) is being expanded from a strength of 60 members to 96, with every seat being contested. Polls have generally projected centre-left nationalist party Plaid Cymru coming in first, closely followed by Reform and Labour coming in third. The outcome of the elections will determine the next steps for the Labour Party and its leadership, with some speculating that a poor performance could lead to a challenge to Prime Minister Starmer's premiership. The results of the elections are expected to be announced in the coming days, with the parties set to respond to the outcomes and outline their next steps.
