Hannah Spencer has been MP for Gorton and Denton since the February 2026 by election, which the Green Party won from Labour after Andrew Gwynne's resignation. She is the Green Party's fifth MP, joining the four returned at the 2024 general election. The win was the most politically significant Green by election result to date and the first time the party has taken a Labour seat in urban northern England.

Before the by election she was a plumber by trade, qualified as a plasterer in early 2026, a Trafford councillor for Hale ward since 2023, leader of the Green group on Trafford Council, and the Green candidate for Greater Manchester Mayor in 2024, where she came fifth. Her trade background is unusual in modern Parliament and is the part of her biography that has done the most political work in her campaign.

The by election win was politically significant because it broke a Labour seat in urban Greater Manchester. The vote was not, in the main, a positive endorsement of the Green Party's full policy programme. It was a coalition of younger progressive voters, anti Labour protest voters, renters squeezed by housing costs, and significant Muslim community support driven by Labour's position on Gaza. Holding the seat at the next general election against a Labour recovery will require keeping that coalition together, which is not a small political project.

Her policy interests have stayed close to her constituency. Housing affordability, renters' rights, public transport capacity, the operational health of local council services, climate policy at the city region scale. The trade skills background gives her a credibility on housing and infrastructure questions that the wider Green Party tends to lack. She speaks about plumbing not as a metaphor but as her former occupation, and the voters who recognise that recognise it for what it is.

The standing Green critique applies to her in modified form. The party is intellectually serious on climate and operationally vague on who pays the bill. Spencer's seat is not affluent. The voters there cannot afford the lifestyle changes that some Green policy proposals would impose on lower income households. She has been clearer than several of her colleagues that any energy transition has to be paid for by capital rather than by working class households, and the constituency has so far accepted that as a serious answer.

The Gaza pressure is one of the political problems she is now sitting on. The Muslim community vote that helped deliver her seat is currently aligned with the Greens partly because the major parties are seen to have failed on Palestine. That alignment is conditional. The political work to keep it requires the party to maintain a clear and consistent foreign policy stance for the rest of this parliament, and the parliamentary group is still small enough that individual MPs carry disproportionate visibility.

Her public manner is direct, unusually free of Westminster speech patterns, and visibly different from the rest of the parliamentary party. She is one of the few MPs who has actually worked with her hands, and she does not hide it. In a Parliament that mostly cannot fix a tap, that is a small but real political asset.

She is one of the more interesting new arrivals in the current Parliament, with a political coalition that is structurally fragile and a personal profile that is structurally durable. Whether the coalition holds through to the next general election depends partly on her work and partly on factors completely outside her control. The Greens will be watching her seat closely. So will the Labour Party. So will Reform.
