The Green Party of England and Wales has elected Zack Polanski as its new leader, marking a shift in strategy that has seen the party surge in popularity. Under Polanski, the Greens have moved away from a sole focus on climate change to emphasise economic inequality, the cost of living, and housing affordability. This approach has resonated with voters, leading to a historic by-election win in February, record results in May’s local and devolved elections, and a tripling of membership to over 230,000 in nine months.
Polanski’s rhetoric often targets “the 99% v the 1%”, advocating for taxing the rich and addressing “rip-off Britain”. The party has also taken strong stances on the genocide in Gaza and trans rights, distinguishing itself from Labour. According to Tarik Abou-Chadi, a professor of European politics at the University of Oxford, this strategy offers lessons for Green parties across Europe that have faced a “greenlash” and declining electoral fortunes.
Abou-Chadi highlights three key lessons from the UK Greens’ success. First, emphasising economic inequality and redistributive policies can broaden a Green party’s electoral coalition without losing credibility on climate issues. Research across 11 European countries shows that focusing on redistribution increases support more than promoting green growth. In the UK, 47% of financially insecure voters with liberal social attitudes chose the Greens, compared to 25% for Labour.
Second, holding strong positions on certain issues creates space to address others. While the Greens maintain their commitment to climate action, Polanski’s boldness on economic and social issues has attracted new supporters. Third, Green parties should not shy away from being strident and ambitious, as progressive voters reward such clarity. The UK example suggests that a shift towards left-wing economic policies can revitalise Green parties that have become too moderate or government-oriented, as seen in Germany and Austria.
