GLA considers investigation into Green Party leader over council tax

The Greater London Authority is assessing a formal complaint regarding whether Green Party leader Zack Polanski failed to pay correct council tax [1, 2].

The situation raises questions about the primary residence of the London Assembly member and whether his financial filings constitute a breach of official conduct rules [1, 2].

Polanski resides on a houseboat moored in east London, located within the London Borough of Waltham Forest [1, 2]. The GLA is reviewing the details of the complaint to determine if a formal investigation into his conduct is warranted [1, 2].

Polanski said he may have failed to pay the correct amount of council tax for the property [1, 2]. This admission has prompted the review of his status as a resident, and the subsequent tax obligations tied to that status [1, 2].

The London Assembly maintains a set of conduct rules that members must follow to ensure transparency, and legality in their personal and professional affairs [1, 2]. If the GLA determines that Polanski breached these rules, he could face disciplinary action or be required to settle outstanding debts with the local authority [1, 2].

This development comes as the GLA evaluates the validity of the complaint filed on May 23, 2026 [1, 2]. The authority has not yet confirmed if a full investigation will be launched, but the assessment process is underway [1, 2].
