So it returned with a scoop, but it was one of no consequence - Princess Di's number one guy speaks. Over on Beeb 1, John Simpson was filing, partly live, an intrepid report from Zimbabwe where Auntie is not allowed. Not only was this a hands-down win where this viewer is concerned but, it seemed, a statement of intent to eschew any ratings-driven race to the bottom. Yet Di was the Ten O'Clock News's second story, suggesting they would have led with it had they got the Khan exclusive. Unsurprising, but disappointing just the same - as so often with today's BBC.
