One of my issues with Starmer is that he only seems capable of reacting not being proactive in any way, and that’s pretty much what’s he’s done again today. If he didn’t have BoJo as his fall guy, he wouldn’t have anything to say.
That's not what I've seen.
Perhaps I've misremembered, but eg at the beginning of the pandemic I remember Starmer being the one coming up with the ideas and Johnson just floundering and fluffing... only to follow Starmer's idea two days later.
I found myself thinking Starmer was in power, but not in office.
