The shift was notable. A week after Keir Starmer said he would resign, YouGov polling showed Labour up two points and the Greens down by the same amount. Might an Andy Burnham premiership mean a rethink for Zack Polanski’s party?

The short answer is it is too early to know, particularly in an era of unprecedented political volatility and the seesawing poll numbers that come with it. This year alone, a five-point Labour lead over the Greens has become a similar margin in favour of the Greens, and then a seven-point advantage for Labour.
