The Greens discover that protest is easier than persuasion

For much of the past decade, the Green Party has occupied an enviable position in British politics. It has benefited from public frustration with Labour and the Conservatives without ever facing the scrutiny that comes with governing. As environmental concerns climbed the political agenda and the two main parties struggled to command public confidence, the Greens increasingly appeared to be the natural home for disillusioned progressive voters.

New polling suggests that honeymoon may already be coming to an end.

Research by YouGov finds that the Greens' net favourability has fallen to its lowest level on record since Zack Polanski became party leader. More than half of Britons now say they hold an unfavourable view of the party, leaving it with a net rating of -16. While the Greens remain one of the better regarded parties in Westminster, the figures represent a notable deterioration from earlier this year, when their standing was considerably stronger.

The decline is significant because it reflects a broader political reality. As smaller parties become more prominent, they inevitably attract the same level of public examination as Labour and the Conservatives. It is one thing to serve as a vehicle for protest; it is another to convince voters that a party is ready for national responsibility. The latest polling suggests the Greens are beginning to encounter that distinction.

The figures also paint a bleak picture for Britain's political class as a whole. Labour, the Conservatives and Reform UK all record similarly poor favourability ratings, with around six in ten Britons expressing an unfavourable opinion of each. Reform remains the country's most polarising political force, inspiring both the highest levels of enthusiastic support and the strongest outright opposition. More than half of the public now hold a very unfavourable view of Nigel Farage's party, illustrating how sharply divided opinion has become.

Perhaps the most revealing findings concern party loyalty. Just 62% of those who voted Labour at the 2024 General Election now say they have a favourable opinion of the party they helped elect. That represents a striking erosion of goodwill in only two years and underlines the continuing fragility of Labour's electoral coalition. Many of those same voters also express positive views of the Liberal Democrats and the Greens, suggesting support on the centre left remains highly fluid.

The picture on the right is scarcely more settled. Conservative voters are almost evenly divided in their opinion of Reform UK, highlighting the continuing competition for leadership of Britain's conservative vote. Meanwhile, a majority of Reform supporters now view Rupert Lowe's Restore Britain positively, although there remains considerable overlap between the supporters of both parties rather than evidence of a decisive split.

The Liberal Democrats emerge from the polling in a relatively favourable position. While rarely commanding passionate enthusiasm, they continue to attract less hostility than any of the other major parties, suggesting that moderation still carries electoral value in an increasingly polarised political environment.

For the Greens, however, the immediate lesson is clear. Rising visibility brings rising expectations. A party that has spent years benefiting from dissatisfaction with others is now finding itself judged on its own leadership, policies and direction. Whether the latest figures represent a temporary setback or the beginning of a more sustained decline remains uncertain.

What is beyond doubt is that no party now enjoys the benefit of public confidence. Britain's political landscape is no longer defined simply by competition between left and right, but by a growing scepticism towards the entire political establishment. The challenge for every party is no longer merely to defeat its opponents. It is to persuade an increasingly doubtful electorate that it deserves to be trusted at all.
