I 100% believe that the reason that Kemi was being kept around is that all of the failure of the Tories can be lumped on her (which is somewhat unfair because she's isn't bright enough to be responsible for any of it) so when it's getting close to the next general election, maybe two years out or so, their will suddenly be letters going in, and a vote of no confidence.

Only they are a bit screwed now though that Robert Jenrick has switch sides. If Farage goes down, and it looks like he's going to, maybe he'll switch back.
