I think the important message here is that BJ is a gift that just keeps giving and will continue to keep giving. There are probably so many stories the media have up their sleeve just to pick the right time
I also think it would be a net positive if Starmer & Rayner both went. They would demonstrate that Labour have "integrity", a card that the Tories ripped up so long ago. Plus it allows a replacement that has some flair for opposition.
