They’ve got the builders in at Buckingham Palace. Having just watched the trailer for the Duke and Duchess of Sussex’s Netflix documentary, someone should tell them to forget about the renovations. What they need is a bunker because boy, is this going to be ugly. Harry and Meghan aren’t just upset about a few courtiers or whingeing about who made whom cry at a bridesmaid fitting. That’s old news. Been there, done that, told Oprah. This time, they’re going for gold. Even after three years, two children, 16 bathrooms and a chicken coop, their rage and fury about their ten terrible minutes in the royal family is baffling.

What the trailer makes clear is that they want to blow up the whole institution and everyone in it. Harry talks about not just his wife’s infamous struggles, but “the pain and suffering of women who marry into this institution, the feeding frenzy”, while pictures of Diana, Camilla and Kate flash up. “There is leaking but also planting of stories,” he says, perhaps referring to the vicious briefing war his parents waged against each other when he was a child, or perhaps to the stories about Duchess Difficult, and the bullying allegations, which she denies, and the story about her wanting Diptyque air freshener in St George’s Chapel, which she does not. “It’s a dirty game,” he says, sadly.
