Hannah Spencer’s victory speech on becoming the Greens’ fifth lawmaker on Friday barely touched on the environmental issues that have defined the party, instead attacking “billionaires” who profit from Britain’s working class.
It was a direct challenge to the governing Labour Party of British Prime Minister Keir Starmer, criticized by some on the left of his movement for abandoning the party’s traditional socialist values to fight a threat from the populist Reform UK.
In a significant political upset that has sent shockwaves through British politics, the Green Party of England and Wales has delivered a major blow to the governing Labour Party, winning a high-profile by-election and directly challenging Labour’s dominance on the left.
In the Gorton and Denton constituency in Greater Manchester, long considered a Labour stronghold, Green candidate Hannah Spencer secured a historic victory in the special election held on Friday. Spencer captured around 40.7 % of the vote, defeating both Labour and the right-wing Reform UK, which came second with roughly 28.7 %. Labour trailed in third place with only about 25.4 % of the vote — a stark reversal of its traditional strength in the area.
The win marks the first time the Greens have captured a seat in a Westminster by-election in northern England and gives them five MPs in the House of Commons, highlighting their rising influence and appeal beyond their core base.
Political analysts say the result is a major blow to Labour leader Sir Keir Starmer, whose strategy to position his party as the centre-left bulwark against the growing far-right vote has been undermined. Instead of consolidating support from progressive voters, Labour has seen a significant portion drift toward the Greens, who campaigned on issues such as economic inequality and local concerns as much as environmental policy.
The outcome also puts pressure on Starmer’s leadership at a sensitive moment in his premiership, raising questions about Labour’s direction and its ability to retain core supporters ahead of future elections. Some of Labour’s key donors and trade unions have already voiced criticism of the party’s centrist shift, saying it risks alienating traditional working-class and left-wing voters.
The Greens’ breakthrough reflects broader fragmentation in UK politics, with voters increasingly willing to back alternatives to the two major parties. While Labour has traditionally been the dominant force on the left, this result suggests many voters are seeking new voices and approaches, especially on issues like inequality, public services, and foreign policy.
The by-election loss also hands momentum to smaller parties such as Reform UK, which finished second and continues to grow its support on the right. For Labour, a party that has governed for much of the past century, the result is seen as a wake-up call and a challenge to its strategy ahead of local and national elections.
As Britain’s political landscape evolves, the Greens’ success in Gorton and Denton is being viewed as more than a symbolic victory it’s a tangible indication that the traditional balance of power may be shifting.
