UK By-Election in Gorton and Denton: A Test for Keir Starmer

A by-election in the Gorton and Denton constituency of Greater Manchester is proving to be a critical test for UK Prime Minister Keir Starmer and the Labour Party. The contest, triggered by the resignation of Labour MP Andrew Gwynne due to health reasons and a parliamentary investigation into alleged inappropriate conduct The Guardian, is being closely watched as a barometer of national sentiment and Labour’s hold on its traditional base.

The Stakes for Labour

Anything short of a victory for Labour’s candidate, Angeliki Stogia, on February 26, 2026, could significantly jeopardize Keir Starmer’s position as Prime Minister. Labour won the general election in July 2024, but by-elections are often seen as indicators of shifting political tides and can amplify internal party divisions. A loss, or even a narrow win, could embolden critics within the party and fuel leadership challenges.

The Contenders

The by-election features a three-way contest:

• Angeliki Stogia (Labour): Representing the governing party, Stogia aims to retain the seat for Labour.
• Matt Goodwin (Reform UK): A former academic and presenter for GB News, Goodwin represents the growing challenge posed by the right-wing Reform UK party. Reform UK has been gaining traction by appealing to voters concerned about immigration and cultural change.
• Hannah Spencer (Green Party): A local councillor and plumber, Spencer offers voters a progressive alternative, potentially drawing support from those disillusioned with mainstream parties.

Eleven candidates are contesting the seat reflecting the diverse political landscape of the constituency.

Recent Polling and Political Trends

Recent polling data suggests a tight race. An Opinium poll conducted in February 2026 showed Labour at 28%, the Green Party at 28%, and Reform UK closely behind at 27%. Opinium This indicates a potential split in the left-leaning vote, which could benefit Reform UK. The Runcorn and Helsby by-election in May 2025, where a former Conservative candidate running for Reform UK snatched the seat from Labour, highlighted the party’s ability to capitalize on voter dissatisfaction.

Internal Labour Divisions

Since assuming power, Starmer has faced internal challenges within the Labour Party regarding policy issues, including welfare spending and tax reforms. The decision to block Greater Manchester Mayor Andy Burnham from contesting the by-election further exposed these divisions. While party leaders cited resource concerns – avoiding another election for the mayoral seat – critics argued Starmer was wary of Burnham’s potential leadership challenge. Manchester Evening News

Implications for the UK Political Landscape

The Gorton and Denton by-election is more than just a local contest; it’s a crucial test of the UK’s evolving political landscape. A Reform UK victory would signal a significant shift in voter allegiances and raise questions about Labour’s ability to hold onto its traditional strongholds. A strong performance by the Green Party could indicate growing support for environmental policies and a willingness among voters to consider alternatives to the two main parties. The outcome will undoubtedly shape the political debate in the months leading up to the next general election.
