Green Party Scores Historic Upset in Gorton and Denton By-Election, Pushing Labour into Third Place and Intensifying Pressure on Keir Starmer

In a stunning result that has sent shockwaves through British politics, the Green Party achieved its first-ever parliamentary by-election victory on February 26, 2026, winning the Gorton and Denton seat in Greater Manchester. Green candidate Hannah Spencer, a 34-year-old local councillor and plumber, secured 14,980 votes (40.7% share), overturning a massive Labour majority of more than 13,000 from the 2024 general election and delivering a humiliating blow to Prime Minister Keir Starmer’s governing Labour Party.
The by-election was triggered by the resignation of former Labour MP Andrew Gwynne for health reasons. What was once considered one of Labour’s safest strongholds—held by the party for nearly a century and won with over 50% of the vote in 2024—saw Labour slump to third place with just 9,364 votes (25.4%). Reform UK, led by Nigel Farage, finished a strong second with 10,578 votes (28.7%), while the Conservatives were reduced to a distant fourth with only 1,721 votes (4.7%). Turnout stood at 47.6%, reflecting significant voter engagement in what became a high-stakes contest.
Hannah Spencer’s victory marks a historic milestone for the Green Party of England and Wales, making her the party’s fifth MP in Parliament and its first in northern England. In her victory speech, Spencer declared the result a “seismic” moment, emphasizing that “there are no no-go areas” for the Greens anymore. Party co-leader Zack Polanski hailed the win as proof that voters are rejecting both Labour’s centrism and Reform’s populism, vowing to replicate the success in upcoming local elections in May 2026. Polanski described the outcome as having “torn the roof off” British politics, signaling a major realignment on the left.
The result represents a profound embarrassment for Keir Starmer, whose Labour government—elected in a landslide less than two years ago—has faced mounting criticism over economic stagnation, public service cuts, immigration policy, and perceived failures to deliver on progressive promises. Analysts point to voter frustration with Labour’s shift toward the center, including austerity measures, slow progress on climate action, and handling of domestic issues, as key drivers behind the collapse. The Greens capitalized on disillusioned left-leaning voters seeking bolder action on the environment, inequality, and social justice—issues where Labour has been seen as too cautious.
Political commentators, including veteran pollster Sir John Curtice, described the swing toward the Greens as “seismic,” with a remarkable 27.5% shift from Labour’s 2024 performance. The outcome highlights the fracturing of Britain’s traditional two-party system: on the right, Reform UK consolidated anti-establishment sentiment, while on the left, the Greens siphoned votes from Labour’s core base. This dual threat—from progressive insurgents and right-wing populists—puts Starmer in an increasingly precarious position.
In response, Starmer acknowledged the result as “very disappointing” but vowed to “keep fighting” and resist “extremes” on both flanks. He emphasized Labour’s commitment to centrist policies, framing the loss as a by-election protest vote rather than a fatal blow. However, senior Labour figures expressed private alarm, with some calling for a tactical leftward pivot to stem further defections. The defeat has intensified speculation about Starmer’s long-term leadership, coming amid other political pressures and low approval ratings.
For the Green Party, the win validates years of grassroots organizing and a strategy of targeting disaffected Labour heartlands with clear, radical messaging on climate, housing, and public services. Spencer, a working-class candidate with local roots, embodied the party’s appeal as an authentic alternative to Westminster insiders. The result could inspire similar challenges in other northern and urban seats, potentially reshaping the electoral map ahead of the next general election.
As British politics enters a more fragmented era—marked by voter volatility and rejection of the status quo—the Gorton and Denton by-election stands as a pivotal moment. It serves as a stark warning to Labour that complacency in safe seats is no longer viable and signals to the Greens that their momentum is real and growing.
The coming months, including May’s local elections, will test whether this upset is an isolated protest or the start of a broader progressive realignment. For now, the roof has indeed been torn off—and Keir Starmer faces the task of patching it before the storm worsens.
