The Queen has caught the UK unawares with her full-throated support of posh people with horses and houses all joyously committing adultery.

Camilla visited the set of Rivals, a show about the well-heeled banging each other in a thinly-disguised Cotswolds, and surprisingly gave it her approval despite the vast gulf between it and her own life.

Producer Jordan Gardner said: “While you’d think the Queen would be above marital infidelity between the double-barrelled where morality is thrown to the wind, she loved it.

“Partly that’s because she was friends with Jilly Cooper, though what they talked about is hard to fathom. Jilly loved big-dicked polo-playing toffs cheating on their wives, and Camilla could not be farther removed from that as she is royalty.

“Nonetheless, though I’m sure she actually prefers the social realism of Ken Loach, she swallowed her distaste and generously behaved as if such aberrant behaviour was normal to her.

“She even suggested a possible subplot about a woman whose ancestor was the King’s mistress who becomes the King’s mistress herself, has his hysterical younger wife bumped off and eventually becomes Queen.

“Sorry, Ma’am, but we’re not doing it. Too far-fetched. Our viewers need posh horsey shagging they can believe in.”
