As pleasing as it would be, Braverman's majority is absolutely enormous, a literal outright majority, and Fareham is about as Tory as it gets, so as bilious as she is, it's unlikely she loses her seat even in the event of a catastrophic Tory wipeout.
Best case scenario is she sticks around because she fancies herself as Furher in the continuity Tory party, finds out that Tory members usually shit the bed at the prospect of electing an ethnic leader even if they agree with them on policy, she fails, and then swans off to the lunatic-right touring scene in the US.
Who is going to end up leading this shower after Sunak falls on his tiny sword is a frightening prospect. The heavier the defeat, the worse and more extreme those who remain behind will be, so if it's not Braverman it's likely to be someone every bit as clueless, vicious, and loathsome, or worse.
