The Green Party has secured a historic victory in a Manchester by-election, winning the Gorton and Denton seat in the House of Commons and delivering a significant setback to Prime Minister Keir Starmer and the governing Labour Party.
Green candidate Hannah Spencer, a local plumber, secured 40.7 per cent of the vote in the constituency. The seat became vacant following the resignation of Andrew Gwynne, who had previously held it with a commanding majority for Labour in 2024.
Spencer defeated Reform UK candidate Matt Goodwin, who received 28.7 per cent, and Labour’s Angeliki Stogia, who secured 25.4 per cent.
Historic First for the Greens
The result marks the first by-election victory in the Green Party’s history and its first parliamentary seat in northern England. The scale of the win exceeded expectations, with polling appearing to underestimate Green support.
The swing from Labour to the Greens was estimated at 26 per cent, bringing the party’s total representation in Parliament to five MPs.
Although voters often use by-elections to express dissatisfaction with the government of the day, the scale of Labour’s defeat in a constituency it had held comfortably just 19 months ago will raise serious questions within the party.
It is also the first time in more than 90 years that the Gorton area will not be represented by a Labour MP.
Market Reaction
Financial markets reacted cautiously. UK government bonds weakened slightly in early trading, with the 10 year gilt yield rising by one basis point to 4.29 per cent. Sterling also softened, trading at around 87.60 pence per euro, its weakest level since mid December.
While the immediate market movement was modest, the political implications may carry greater weight.
Pressure on Labour’s Strategy
The outcome is likely to intensify debate within Labour about its strategic direction under Starmer’s leadership.
Following a recent by-election loss in Caerphilly in the Welsh Parliament, the Welsh Senedd, to Plaid Cymru, the Manchester result reinforces signs of strain within Labour’s traditional support base.
Under former chief of staff Morgan McSweeney, who recently left government after controversy surrounding the appointment of Peter Mandelson as US ambassador, Labour had attempted to broaden its appeal to more right of centre voters.
This approach included firmer rhetoric on immigration, adjustments to positions on transgender rights and a strong emphasis on fiscal discipline. Critics argue that such positioning may have unsettled parts of Labour’s progressive base, creating space for the Greens to gain ground.
A Shifting Political Landscape
Spencer said voters were looking for an alternative to established political parties and signalled that the result reflects a desire for change.
The victory highlights the expanding reach of the Green Party beyond its traditional areas of strength and suggests that northern constituencies may become increasingly competitive in future elections.
For Starmer, the challenge now lies in balancing electoral strategy with party unity, a test that could shape the next phase of his leadership.
