Greek millionaire Dimitri Mavrommatis raised a record-breaking £10.4m ($20m), nearly double expected, from the auction of his household works of art and furniture at his Chester Square residence last night.

Sotheby's organised the "Furniture and Works of Art",sale from the personal collection of Mavrommatis. The auction was expected to raise between £5.5 and £8.7m from the 85 lots, but current soaring international demand for art sent prices rocketing.
