Greens Gain Momentum in Polls
Since Zack Polanski assumed leadership of the Green Party in September 2025, the party has experienced a notable increase in public support, often referred to as the "Polanski effect." Recent polling data indicates that the Greens have risen by an average of four points, currently polling at 13.5%, trailing Labour at 18.6%. However, there is significant variability in polling results, with some firms like YouGov reporting as high as 17% support for the Greens, while others, such as Focaldata, show only 10%. This discrepancy may stem from differences in polling methodologies, including whether the Greens are included as an option.
Demographic Shifts and Key Issues
A significant factor in the Greens' rising support is their appeal to younger voters. Polling from YouGov reveals that support among 18- to 24-year-olds surged from 26% in early September 2025 to 45% by mid-January 2026. This demographic shift poses a potential threat to Labour, particularly in upcoming local elections in London, where young middle-class professionals are a key voter base.
The primary concerns for Green supporters include the cost of living, the NHS, and the environment. However, new Green voters prioritize economic issues more than existing supporters, indicating a shift in the party's messaging may be necessary to align with these voters' interests.
Polanski's Leadership and Public Perception
Zack Polanski's leadership has drawn mixed reviews, reflected in his net favourability rating of -15 points, with 20% of the public viewing him favorably and 35% unfavorably. Despite this, he remains more favorable than most national political leaders, with a significant portion of the public still undecided about him. Experts suggest that Polanski's anti-establishment stance resonates in a political climate where traditional parties are perceived to have failed.
Tactical Voting and Future Prospects
Looking ahead to the next general election, the Greens are positioned to capitalize on Labour's decline in progressive urban areas such as Bristol, Manchester, and Sheffield. MRP polling estimates indicate that the Greens could secure over 30% of the vote in 16 constituencies, potentially winning nine seats overall. This scenario highlights the importance of tactical voting, as there are 179 seats where the combined vote share of the Greens, Labour, and the Liberal Democrats exceeds that of the Conservatives and Reform UK.
Official Statements & Responses
Experts like Prof Sir John Curtice have noted that the Greens' rise adds to Labour's challenges, particularly among younger voters. Joe Twyman from Deltapoll emphasized the need for the Greens to develop a robust national campaign strategy to convert polling support into actual votes.
Criticism & Opposition
Despite the Greens' momentum, there are concerns about their ability to maintain this support. Analysts warn that the party must broaden its appeal beyond its current base and address the uncertainties surrounding its electoral strategy.
