Even with the dramatic swings in the 2026 local election, LibDems won more seats than the Greens, Labour won roughly 2x the Greens - and Reform won roughly 3x the Greens.
I see no evidence that the Greens, or any other party are the dominant anti-right party. It's gotta be Labour for now.
The sooner the UK embraces a coalition approach, led by Labour with serious compromises by all, the better.
At least until genuine electoral reform.
