They live in a five-storey house off Cadogan Square in Chelsea - the house raided by police after Mrs Rausing was found trying to enter a party at the American embassy allegedly with drugs in her handbag - and they are surrounded by the usual trappings of wealth, including servants and expensive cars.
She is a keen tennis player and takes a generous interest in the Mary Rose Trust, established to save HenryVIII's salvaged battleship.
The couple have also given large amounts to the Royal Opera House, which they attend often.
But they are not socialites in the usually accepted sense.
One person who knows them said: "It is very difficult to have a conversation with him. He has a detached, non-communicative manner.
"I asked him what his interests were and he said, after a long pause, opera.
"'What have you seen recently?' I asked. He seemed stumped, then turned to his wife and asked her. Neither could remember."
