Public opinion of the UK's Green Party has seen a notable decline since Zack Polanski assumed leadership, with a recent YouGov poll revealing a net favorability score of minus 16, the lowest recorded to date. According to the research, 52 percent of Britons hold a negative view of the party. This represents a substantial decrease from the plus five rating the party held shortly before Polanski took charge in September of last year.

The YouGov findings suggest that while the Green Party has achieved success in local and by-elections, its broader public appeal may have diminished as its profile has increased.

The poll also provided insights into the public perception of other political parties. The Labour Party recorded the highest unfavorability level at 63 percent, with only 28 percent viewing the party positively. Reform, however, registered a strikingly high percentage of 'very' negative views, at 53 percent. YouGov research showed the party's net favourability score has dropped to minus 16 - the lowest recorded to date. Some 52 per cent had a negative view

The research also touched upon potential challenges for Reform leader Nigel Farage, as 58 percent of those who voted for Reform in 2024 also expressed a favorable view of Restore Britain, a new party led by Rupert Lowe. Farage has reportedly been working to counter the challenge posed by Lowe's party on his political right. Both Reform and Restore Britain garnered significant support in the recent Makerfield by-election, although the seat was ultimately won by Andy Burnham. The Green Party is reportedly aiming for a strong performance in the upcoming Greater Manchester Mayoral contest, a position formerly held by Burnham, who is now expected to become Prime Minister. However, Reform is also directing considerable resources toward this mayoral race.
