A Russian oligarch will this week accuse Sotheby’s of helping an art dealer to trick him into overpaying for art masterpieces including Leonardo da Vinci’s Salvator Mundi, which went on to become the most expensive artwork ever sold.
Dmitry Rybolovlev, ranked as the world’s 180th richest person with an estimated £9bn ($11.4bn) fortune, is suing Sotheby’s in New York, where the London-founded 280-year-old auction house is now headquartered.
