Ahead of the auction, The Market’s chief executive, Mark Livesey, said: “On one hand it’s a 1994 Jaguar, and on the other hand it’s actually an ex-royal car as used by the late Princess Diana.”

He explained that the car had been used by the princess for about three years, up until her death in 1997, and that it had “played a role in some of her most famous moments”.

“She was transported all around London and UK in it and famously popped out of it wearing the black revenge dress after Charles had made a confession to the media earlier that day,” he said.

He said the history of the car “definitely makes it special”.

“Whenever any of us actually meet or come close to a really famous person, you get a funny feeling,” he said.

“To have, or even own, something that belonged to them, it definitely adds an enormous value.”

The Jaguar was not the first celebrity vehicle sold by The Market – with George Michael’s Range Rover and Elvis Presley’s Cadillac also sold by the auction house in the past.
