The Torys are split, I think both sides know...
For what it's worth, I think there are more than two main 'sides' in the Tory party presently. You've got the current group of Sunak supporters (who may only back him because more mutinies in a single election cycle would look terrible), you've got Truss's low-tax zero-regulation 'growth at all costs' lot and you've got Johnson's "stoke culture wars and make any kind of promise to limp over the GE line and keep our seats" faction.
This is without factoring in smaller divisions such as the ERG kicking off over any threat to implement the NIP they voted for, as well as any possible remaining rump of sensible Tories who actually want a workable NI solution.
Because I sincerely believe the Tories see no difference between their party and the country, they are one and the same in their self-entitled, born to rule pig fucking minds.
One of the main apects of Right Wing thinking is that there a group of people who naturally 'should' be in power and making decisions (which is of course them) and everyone else who shouldn't. It's totally antithetical to their sense of how the world 'should' work that others get to tell them what to do (how much tax to pay, introduce laws they don't support, all that stuff).
The actual governance aspect is secondary to ensuring that the 'right' people are in charge. The trouble for them right now is that they are deeply divided on the best way to retain that power.
Ulimately this is what's driving Sunak's inaction on anything important, he can't be sure of support from the party. So all they focus on is the small boats issue, Ukraine, and trying to associate Labour with the strikes in general, and Starmer with Corbyn specifically.
