Millionaire Hans Rausing has appeared in court charged with preventing the lawful and decent burial of his wife Eva.
Rausing, who looked frail in the dock at West London Magistrates' Court, was granted conditional bail to appear again at Isleworth Crown Court on July 26.
Police discovered the decomposing body of mother-of-four Mrs Rausing after they arrested her husband - the heir to the Tetra Pak millions - on suspicion of driving under the influence of alcohol or drugs last Monday.
Mrs Rausing, one of Britain's richest women, was found in an annexe on the second floor of the opulent Cadogan Place house in London's Chelsea which she shared with her 49-year-old husband.
Bearded and bespectacled, Rausing spoke only to confirm his name, age and address in court.
Rausing, whose family made a fortune when they sold the Tetra Pak business in the 1990s, was wearing a dark suit and light blue shirt with no tie.
District Judge James Henderson told him: "I grant you bail on two conditions. The first is that you must reside at the Capio Nightingale Hospital and that you live there and sleep there overnight, and you do not leave that hospital unless you are accompanied by a member of hospital staff."
