Yeah... Obviously not great that Polanski bungled up (no pun intended) what counts as his "main" residence for council tax purposes. But honestly, it happens. I know people to have accidentally failed to register to pay utilities, or forgot to register that they moved and this failed to vote in the election. He's admitting it and paying. That's more than most politicians do when accused of something.
Polanski is definitely taking a lot of flak and every mistake seems like it'll get reported on. Can't wait for a "tan suit" or "Dijon mustard" moment. He's had some questionable things turn up about his past for sure though, sadly.
Either way, it shows the Greens are getting popular and I'll take that. If it turns out Polanski is unfit to lead then hopefully someone else can take his place.
