What happened

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.

Why it matters

The Green party leader has faced questions over whether the houseboat, moored in east London, was his primary residence.

Common ground

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.

Perspective signals

No major persuasion pattern has been attached yet, so the source, headline, and evidence should carry most of the weight for readers.
