DB has a long history of ill-feeling with the BBC. As I said, upthread, he thought they were stuffed shirt, know-nothing Oxbridge types who looked down on him because of his background while not having a hope in hell of being able to do his job for 10 mins, let alone 3 hours.
There's a fantastic rant on Youtube, where he devoted a show to attacking his bosses who had just cut his programme in a shake-up - without having the decency to tell him before he read it in the press. He called them 'pin-headed weasels' live, on-air. Amongst other things.
On this occasion, he was rung up early in the morning to tell him he'd been sacked, without giving him a chance to explain. Just a pompous lecture. He maintains that anyone else would have been called in to discuss it, agree an apology etc. He's probably right. 6 of one, half a dozen....
'So you think I'm a racist?' Expletives deleted. Or, as he said in his Nottingham show, 'When life gives you lemons, throw them back at the people who call you a racist.'
Whether you like him or not, it helps to know a bit of the history before rushing to judge the motivation of someone you know little about.
Btw, didn't the H&M wedding clash with the Cup Final? Or was that Eugenies? I can easily imagine he didn't notice pictures of Doria. He's interested in football, music on vinyl, Disney and Mongolian throat-singers amongst other arcana. His journalism is restricted to music reviews, old interviews with rock stars, and sport. It's never been his job to be abreast of current affairs. I really can't see him sitting round the studio discussing the royals.
