In a shock poll, the Green Party under its new leader Zack Polanski has pulled ahead of Labour (just).

According to the pollsters Find Out Now, the Greens are on 15%, the same level as Labour. But as economist James Meadway notes, if you look at the detailed results, the Greens are on 15.31%, compared to 15.23% for Labour.

This is being a bit mischievous, because polling has a margin of error. But the trajectory is clear - the Greens are surging, and Labour is falling back. The Greens are enjoying their best polling in their history. Just 13 months after winning the election, Labour is on its worst polling recorded in the post-war period.
