Takeaways from a UK special election won by the Green Party over Starmer's Labour

Britain’s Green Party has scored a surprise victory in a special election for a seat in Parliament in a blow for Prime Minister Keir Starmer and his Labour Party. On Thursday, voters in Gorton and Denton put Labour in third place. The Greens finished first, and hard-right party Reform U.K. second. The contest is only for one seat, but it shows how divided politics has become and the waning dominance of the Labour and Conservative parties. Starmer already faces anger inside Labour over a sluggish economy and unpopular policy reversals. It raises the prospect of a challenge to Starmer's leadership from within his own party.
