The Green Party leader has apologized for failing to pay council tax while living on a houseboat in London, describing the situation as an "unintentional mistake."

The Green Party confirmed that its leader had been residing on the houseboat until recently and acknowledged that council tax may not have been paid on the property. The party made the admission after questions were raised about the leader's living arrangements and tax obligations.

In response to the revelations, the party leader issued an apology and stated that he had "immediately taken steps to pay any council tax" that might be owed. The leader characterized the failure to pay as unintentional rather than deliberate tax avoidance.

Council tax is a local government levy charged on residential properties in England, Scotland and Wales, with houseboat residents typically required to pay the tax to their local authority. The amount owed and the duration of the unpaid period have not been disclosed.

The Green Party has not provided additional details about when the tax issue was discovered or the total amount involved in the settlement with local authorities.
