DH will be disappointed, he predicted a Boris return last week, before Truss even resigned.
I'm disappointed as I am a bit of accelerationist and enjoy the drama and prospect of destruction of the Tory party, but for the country/economy Sunak being in charge for a few months/years is for the best. If we had a GE soon and Labour won (likely), then they'd just be inheriting chaos and probably be out after a term.
Let the Tories clean up their own mess for a little while longer.
