London assembly officials are weighing up whether to launch an investigation into Zack Polanski after he admitted he may have failed to pay the correct council tax while living on a houseboat in the capital.
The Green party leader has faced questions over whether the houseboat, moored in east London, was his primary residence. A spokesperson for his party had described the situation as an “unintentional mistake” and said Polanski had “immediately taken steps” to pay any tax owed.
