Zack Polanski’s path from influencer to UK political leader has reached a key milestone: His Greens won a seat in the Manchester constituency of Gorton and Denton, its first major electoral triumph since he took over party leadership in September.

While membership in the once-fringe group has tripled to about 200,000 during his tenure, the by-election win has put him right in the eye of the political storms buffeting the UK.
