Britain's local polls will have a huge national impact

British voters will cast ballots on Thursday in elections that could hasten the end of Prime Minister Keir Starmer's troubled term and confirm that an increasingly fractured United Kingdom has entered an era of messy multiparty politics.

Starmer's centre-left Labour Party is expected to take a battering in elections for local authorities across England and for semiautonomous legislatures in Scotland and Wales.

With the prime minister's popularity in the doldrums from a weak economy and repeated questions about his judgment, rival parties are framing Thursday's votes as a referendum on Starmer and his 2-year-old government. "Vote Reform, Get Starmer Out" is the campaign slogan of the hard-right party Reform UK. The next national election does not have to be held until 2029, but a wipeout on Thursday could tip a restive Labour Party into revolt against its unpopular leader.

Less than two years after winning a landslide election victory, "Keir Starmer has become a vessel for people's disappointment (and) disillusionment," said Luke Tryl of pollster More in Common. Starmer's popularity has plunged after repeated missteps since he became prime minister in July 2024. His government has struggled to deliver promised economic growth, repair tattered public services and ease the cost of living — tasks made harder by the US-Israeli war with Iran, which has choked off oil shipments through the Strait of Hormuz.
