Even for the most stalwart party member, the meteoric rise of popularity for the Green Party since the 2024 General Election would have caught them off guard. After a record-setting performance at the election – 6.8% vote share and four returned MPs – there were questions of how they could ensure they went from strength-to-strength. As it turned out, this came in the form of a new leadership team.

In September 2025, Zack Polanski was elected leader of the Green Party, with Rachel Millward and Mothin Ali elected as co-Deputies. Since then, the Greens are now averaging 15% in national polls, reaching highs of 18% with certain pollsters – and beating Labour in multiple polls.

So how did this happen and how do they take advantage of it to ensure that 15+ percent turns into national conversation and significant seat returns?

To discuss all of this, we’re overjoyed to have Compass Deputy Director Lena Swedlow joined by Green Party Deputy Leader Rachel Millward.
