Kay Burley loves her job and thinks journalism is the best career in the world. She tells me this around half a dozen times in a 25-minute interview.

But if she had to choose another profession, I'd recommend teaching. None of her students would dare be late for class or skimp on their revision. And they'd eventually learn not to talk back at her.

Unfortunately for me, after a trek to Sky News's Osterley office ("we're far out – in more ways than one," she tells me) I was five minutes late, and there were, it emerged, a few holes in my research.
