Re: Delighted ...
Tory MPs wanted Sunak from day one. That's why they gave members the choice of either him or the Queen of Turnips. Unfortunately he was in charge of the economy going to shit and people weren't going to forgive him for that so Liz got it instead.
Now it looks for all the world like it will be him and Boris as the final two, which would be a literal "vote Rishi or the party gets it.". I'd expect that Boris will step down at the last minute Leadsom-style allowing Rishi to be appointed by the party elites instead,
As for the plan beyond that, Britain has a surfeit of gas and Europe is expected to run out this winter. I'm guessing someone behind the scenes thinks they can gain some post-Brexit concessions if they have that as a bargaining chip. Not saying it'll work but I can't see anything else that might save the party.
Or maybe they just want to add the first non-white PM to the party's portfolio before they crash out of politics for another decade. Wouldn't bet either way.
