James Tapsfield: Will Zack Polanski's Golders Green row prove costly?

As Kermit the Frog once said, it's not easy being green.Zach Polanski might be agreeing after he had a taste of politics at the sharp end.Polanski has been getting rather more scrutiny, as it looks like the Greens are going to make big gains from Labour in these local elections.But there's been particular focus on Polanski's decision to repost criticism of the police over the detention of the Golders Green suspectThe Greens might be reflecting that politics is not quite as easy as they thought it might be.
