Polanski has said he will remain as Green leader despite mounting criticism from within the party. The position follows a dispute over Zionism and a defeat in a by-election.
The leader of Jewish Greens has called for Polanski to resign, linking the demand to the controversy and the electoral result. No further details of the Zionism row or the by-election have been provided.
Polanski has nevertheless vowed to continue in the leadership role. His decision leaves him facing continued opposition from parts of the party as criticism grows.
The latest position is that Polanski intends to stay on, while the call for his resignation remains unresolved.
