No basis for this but my feeling is that if Kemi did not have support, she would have been moved on some time ago. That others are not vocal might be for a number of reasons, perhaps including that it would "prove" the absurd and immature charge that she's weaponising the issue or some such.
Other Tory MPs who have been quiet, definitely signalled support for Kemi after the WESC if you look at their likes and retweets. Of course that then had a basis in proper procedure as the matter was being discussed in a Parliamentary setting, and makes the charge of "blah blah culture war epidemic you're just mean" much harder to stick.
I also think some credit has to be given to Keegan on the schools guidance here. She has either moved her position or she's been persuaded to for some reason. If she was in the Nokes mindset, you'd expect a resignation. Or she could have dithered and delayed, and dragged it out. So too, could Sunak.
Janice (and The Times as a paper) has gone increasingly soft on whole issue. That's a giant 🚩 we should be taking note of.
