A London Assembly investigation clears Zack Polanski of any breach of the Assembly’s code of conduct in relation to a council tax dispute. According to the findings reported by multiple outlets, the investigation concludes that Polanski’s tax affairs do not fall within an “official capacity” and therefore are not regulated by the relevant code. The inquiry is framed around whether his involvement in the council tax issue should be considered part of his official duties, and the result is that it is treated as outside the scope of the code. As a consequence, the probe does not move to sanction or impose formal outcomes tied to alleged conduct under the Assembly’s rules. The reporting characterizes the decision as contentious, but the core point in the sources is consistent: the investigation’s conclusion rests on jurisdiction and scope—specifically, whether the matter is covered by the code—rather than on an additional finding of wrongdoing within an official remit.
