Where others began by expressing regret over the Horizon scandal, Kemi said nothing. Because she feels nothing

Look on the bright side. Kemi Badenoch lasted two and a half hours in the witness stand at the Post Office inquiry without losing it. She didn’t get into an argument with Jason Beer, the counsel for the crown, though that could be because his questions were not unduly threatening. After all, we were there to hear Kemi’s version of events. Other versions of the truth may be available. Nor did she square up to any of those in the public gallery who laughed when Beer thanked her for answering “some” of his questions.

Not that Kemi nailed it. Like many narcissists, she is a curious mixture of the thick- and thin-skinned. She likes to present herself as a no-nonsense, tough woman. Someone who isn’t afraid to go toe-to-toe with her opponents. Who can tell it like it is. But beneath the surface there’s a vulnerability that she despises. It’s why she lashes out so readily. The person she dislikes the most is herself.
