The Green Party achieved a stunning victory in the Gorton and Denton by-election, one of Labour’s safest seats, highlighting the growing fragmentation of British politics. Hannah Spencer, a 34-year-old plumber running for the Greens, secured 40.69% of the vote, finishing 12 points ahead of Reform UK’s Matt Goodwin at 28.73%. Labour’s Angeliki Stogia placed third with 25.44%.
This defeat ranks as Labour’s sixth-worst by-election loss by majority size in history. The Gorton seat had remained in Labour hands for over 90 years. In Greater Manchester since World War II, Labour defended 20 by-election seats and won 16. Turnout matched the general election level, underscoring the result’s significance amid a government lacking a honeymoon period and a prime minister hitting record-low popularity.
Labour’s Strategic Misstep on Burnham
Labour lost ground over a month earlier when its national executive committee rejected Andy Burnham’s candidacy by an 8-1 vote. Greater Manchester’s mayor, Burnham, emerged as the potential savior for the seat. Prime Minister Keir Starmer opposed the move, citing risks of a regional mayoral by-election and Burnham’s popularity as a leadership rival. Burnham consistently garners two-thirds support in mayoral races, outpacing Spencer by 375,000 votes in the 2024 contest.
Manchester MP Lucy Powell, now Labour’s deputy leader, cast the sole vote for Burnham. The outcome intensifies scrutiny on Starmer, though challenges persist: uniting 80 MPs for a leadership bid proves daunting, and economic upticks may curb shifts to the Greens on the left and Reform on the right via falling net migration.
Upcoming Electoral Challenges
Labour faces tougher tests in 69 days with Scottish parliament, Welsh Senedd, and English local elections. The party risks losing Senedd control and many council seats it currently holds.
The Decline of Two-Party Dominance
Gorton and Denton confirm eroding voter loyalties. Four-party dynamics prevail in Scotland and Wales, while Liberal Democrats hold sway in England, ending the traditional duopoly. England now sees a viable left-wing challenger to Labour in the Greens and a right-wing threat from Reform against both major parties.
Vote splits offer Labour slim comfort; a divided right could secure victories on low vote shares, as in 2024 when it claimed two-thirds of Westminster seats. Yet fragmentation brings downsides. The campaign turned toxic: Greens faced sectarianism charges over Urdu leaflets and a video of Starmer with India’s Narendra Modi targeting Muslim voters, while emphasizing Gaza alongside local issues.
Reform drew racism accusations for courting white voters and ignoring the Muslim minority. Candidate Matt Goodwin sparked controversy with views questioning British identity for UK-born non-white people.
First-past-the-post voting amplifies disproportionality in multiparty contests, but multi-party fragmentation appears entrenched.
