Truss’s best (I’d say only) chance to get a win is to call a snap election.
I'd disagree and say Truss's best (only) chance is to just hold on and hope the economic picture looks better in autumn 2024. It's not a great plan but surely calling an election this year as everything is at it's worst would be doomed to fail. Any honeymoon bounce would immediately disappear once an election was called.
The economic situation isn’t going to improve with John Redwood in the Treasury.
Yeah things are unlikely to get notably better in 2 years, but still, the Tories best hope is to gamble on the future. Any honeymoon would quickly fade (like May's) on campaign and we would be back where we are now. Right now is a fine electoral position, but not if you are a Tory of course. Plus if one happens to be in the 'inevitable loss' camp, waiting gives you 2 more years of power.
That all said, if the rumors about Boris are true, I'm sure he will be lobbying hard for that early election, cause a Tory loss means potentially only a brief time in the wilderness. And it's Truss, so no idea if she'll resist this call....
