His seat is one of the safest in the country. It’s been Tory for more than a hundred years, and Sunak’s majority at the last election was 50 percentage points higher than the nearest candidate, meaning it would probably take voters deciding to back a particular opposition candidate to unseat him.
His seat was, I think, one of the two the Tories were predicted (by John Curtiss, I think) to hold under the worst opinion poll during the Truss lettuce.*
So it’ll be unlikely he’ll lose his seat. Will he show himself a liar by quietly resigning his constituency after the inevitable leadership election? Gordon Brown stayed on for the full 5 years after he lost (and was a good constituency MP), while Theresa May has been there for 5 years after she was ousted.
*I was going to call it an era, but it doesn’t really count as such, so we need a new word.
