They're not pro Boris, they want Stewart as leader because he's a neoliberal like them.
The BBC is soft left/ neoliberal/ globalist, Corbyn is too far-left for them but they're not right-wing.
Pretty much every programme they make is left-wing/ PC.
I watched that Good Omens show recently, God was a woman, Adam and Eve were black, this was in the first 5 minutes.
As Ally Ross said recently, the BBC drama department is just one big diversity workshop.
