'Brighton Greens were headed one way, out of the door'

My forecast for last week’s local elections in Brighton was met with derision, not least by Green Party councillors. Even Labour activists felt I had been over-optimistic on their behalf. Few others predicted Labour topping 30 seats. I had said that Labour would win 31 seats, the Greens 12, the Conservatives eight, and that there would be three independents.
