UK Green Party leader Zack Polanski is facing renewed scrutiny over whether his party's rapid rise in the polls can be sustained, according to commentary published in The Guardian, as the party heads toward another closely watched byelection.
Polanski built his profile as one of the most vocal critics of Prime Minister Keir Starmer's Labour government, arguing it had failed to pursue sufficiently progressive policies, had not spoken out strongly enough on Gaza, and had struggled to generate public enthusiasm.
That critique helped drive a surge in support for the Greens, who reached a record high of 18% in opinion polls and won the Gorton and Denton byelection against Reform UK's Matt Goodwin.
The commentary suggests that an upcoming byelection could serve as a test of whether the party's gains represent a durable shift in British politics or a temporary surge that has already begun to fade.
The piece frames Polanski's situation as illustrative of a broader pattern in British politics, where rapid rises in popularity have at times been followed by swift reversals in public and political standing.
