In February 2026, Britain's Green Party achieved a stunning victory in the Gorton and Denton by-election, defeating both the governing Labour Party and far-right Reform UK in what was once a Labour stronghold. This historic result marked the first-ever parliamentary by-election win for the Greens, pushed Labour into a humiliating third place, and signaled a dramatic breakdown of the UK's traditional two-party political system.

Voters in the Greater Manchester constituency of Gorton and Denton cast ballots in a closely-watched by-election to fill a seat vacated by a Labour MP who resigned over racist and sexist WhatsApp messages. The contest pitted the left-wing Greens directly against far-right Reform UK, with Labour defending what had been considered a safe seat for almost a century.
As votes were being counted overnight, the Financial Times reported that Labour was on course to lose the by-election, describing it as a potential severe blow to the ruling party after a divisive campaign. The early indications pointed to a Green Party victory in what would be a major upset.
Official results confirmed a stunning Green Party victory with Hannah Spencer winning 14,980 votes, beating Reform UK's Matt Goodwin (10,578) and relegating Labour's Angeliki Stogia to third place with just 9,364 votes. This marked the Greens' first-ever parliamentary by-election win and made Spencer the party's fifth MP in the 650-seat House of Commons. The 34-year-old plumber and councillor's victory margin was 4,402 votes.
Labour Party chair Anna Turley conceded the result was 'clearly disappointing' as the party grappled with losing a seat it had dominated for almost a century. The defeat put additional pressure on Prime Minister Keir Starmer, who was already facing calls to resign following weeks of political turmoil.
Political observers described the result as 'the worst outcome' for Labour, highlighting a dangerous split in the left-wing vote that could be replicated at upcoming May local elections. The Financial Times noted this fracturing could create lasting problems for the governing party's electoral prospects.
Analysts and international media emphasized that the outcome demonstrated the fundamental breakdown of Britain's traditional two-party system. With two insurgent parties holding only 13 seats combined now directly challenging Labour's dominance, the political landscape appeared to be undergoing a dramatic transformation.
Media analysis highlighted that Green candidate Hannah Spencer's campaign partly focused on her party's pro-Palestinian position, which appealed to Muslim voters who comprise approximately 28% of the constituency's population. The Greens' openly pro-Palestinian stance and opposition to what they called Israeli 'genocide' in Gaza was seen as a key factor in their victory.
Prime Minister Keir Starmer addressed the defeat by criticizing parties at both political 'extremes,' acknowledging the result was 'very disappointing' while insisting he understood voter frustration. His response attempted to position Labour as the moderate center while facing mounting pressure from both the left-wing Greens and right-wing Reform UK.
The Times of Israel characterized the Green victory as 'a major boon to anti-Zionism,' noting that the BDS-supporting Greens had successfully called on voters to punish Starmer for supporting what they characterized as 'genocide' in Gaza. This added a controversial dimension to the election's significance beyond domestic UK politics.
Major international outlets including the Los Angeles Times described the outcome as 'a nightmare for Prime Minister Keir Starmer,' with widespread speculation about how long he could continue as Labour leader. The result was seen as a heavy blow coming less than two years after Labour's landslide general election victory.
A YouGov poll published four days after the by-election showed the Greens had overtaken Labour in national polling, trailing Reform UK by just two points. This suggested the by-election result might reflect broader shifts in voter sentiment rather than being an isolated upset, raising further questions about Labour's future prospects.
