In 2015, King Salman threatened to go over his limit on his American Express Centurion Card. He spent £452m on a 440 ft super-yacht – bought from a Russian tycoon after being wowed by it while on holiday France. Feeling that it looked a bit bare and needed some decorating, he then acquired Leonardo Da Vinci’s £350m Salvator Mundi masterpiece and is believed to have installed the painting on the mega boat.
