Overview
- The Greater London Authority monitoring officer has received two formal complaints from Labour and the Conservatives and began an initial assessment of whether to open a formal standards investigation on May 22–23.
- Waltham Forest council has launched its own inquiry to decide if the narrowboat mooring was Polanski’s sole or main residence and therefore liable for council tax.
- Zack Polanski has acknowledged an "unintentional mistake," apologised and said he has begun steps to pay any council tax found to be due.
- Analysis by a tax lawyer cited in reporting suggests the boat and mooring would likely be rated Band A, which could mean roughly £4,000 of council tax for three years plus possible penalties and scrutiny under the Local Government Finance Act.
- Rivals have pushed for formal action and some commentators have urged changes to oversight rules, so the case could produce both disciplinary outcomes for Polanski and calls to close gaps in how assembly members’ tax and residency are checked.
