LONDON — The son of one of the world’s wealthiest men pleaded guilty Wednesday at a west London court to a charge of preventing the lawful and decent burial of his wife, Eva Rausing, a court spokesman said.

Hans Kristian Rausing was charged last month after his wife’s decomposing body was discovered by police as they searched the couple’s central London mansion.

His guilty plea at Isleworth Crown Court was confirmed by communications officer Steve Murphy.

He also admitted driving a vehicle while unfit through drugs, the UK’s Press Association news agency reported.

Rausing, 49, was given two suspended sentences, one for each charge, the news agency reported.

Both Eva and Han Kristian Rausing, who had four children together, had battled with addiction for decades.

The court was told that Eva Rausing had returned to London on April 29 after having spent time in a clinic in California, PA reported.

The court heard that a pacemaker she had fitted because of heart problems indicated that the likely time of death was early on May 7, the news agency said.

The 48-year-old’s body was found on a bedroom floor on July 9, concealed under trash bags and clothing, the news agency said. A toxicology report revealed traces of cocaine, opiates and amphetamines in her body.

Her husband is the son of Hans Rausing, who is worth an estimated $10 billion, thanks to the family’s connection to Swedish packaging giant Tetra Laval.
