The Green Surge - Projecting the Party’s Future Seats

The Green Surge - Projecting the Party’s Future Seats - Analysis

Since Zack Polanski became leader of the Green Party on 2 September 2025, the Greens have enjoyed a surge in polling. What are their current general election prospects, and where are these gains concentrated? Polling After Polanski’s win, Green polling immediately started increasing. At the time of his election, they were at 8. 9% in the polling trend. This increased to a high of 15. 4% in November, at which point they had overtaken the Liberal Democrats for fourth position. They have declined slightly since then, settling at 12. 5% today. Overall, this represents a 3. 6-point increase since Polanski took over the leadership. Regionally, they have made consistent gains across all areas compared to their GE2024 results. Yorkshire, the North West, and the West Midlands show almost 10-point growth. London’s growth appears lower, which may be the result of sub-sampling noise - worth monitoring over the next few months in the run-up to the local elections. It is not surprising, then, that of the five seats they are currently projected to gain, three are in Yorkshire. The remaining two are in the North West and the South West, respectively. All five of these new seats would be gains from Labour, although in Huddersfield they would likely be fighting Reform for the seat, with Labour in third. They are also projected to increase their margins in their four current seats. Unexpectedly, Reform are projected to be a very distant second in all four. Target Seats Currently, there are three additional seats the Greens will be looking to target: Bristol South Manchester Withington Brighton Kemptown and Peacehaven All three have a current projected gap of less than 5% to Labour. Bristol South and Manchester Withington have gaps of only 2.
