Do you really think Truss will be allowed to call an early election ? Especially when Boris was rebuffed ?
The last shred of unwritten constitutionality we have is that the Monarch is needed to dissolve parliament and at the moment - with a Tory majority of 80 - there is no need for an election. With the Queen fading by the hour, it's a delicate time to pick a fight with the Monarch.
All of which being said, I'm starting to see President Johnson (no, not that one) taking form through the fog. So maybe ousting the Queen now while it's easy is the plan ?
Already the potential censure of Johnson has had it's teeth pulled.
Just recast Brexit in terms of the reformation and you have it. Truss previous Remain credentials will forever be used as proof that she hasn't truly converted to the One True Religion. Catholicism has been replaced by Europhilia in the secular tale of these islands. With Scotland (once again) cutting it's own swathe.
And with the mainstream press playing the role of the Praetorian guard, all our history is catching up with us.
