A German aristocrat has been found dead in his apartment in an exclusive area of west London.
Paramedics were called to 44-year-old Count Gottfried von Bismarck's flat in Draycott Place, Chelsea, at 1324 BST on Monday afternoon.
Scotland Yard have formally identified him and his next of kin have been informed.
Last August a man died after falling 60ft (18m) while partying at Count Gottfried von Bismarck's apartment.
The coroner, Dr Paul Knapman, had recorded a verdict of misadventure and said that Anthony Casey, 38, had significant levels of cocaine in his blood
Coroner Dr Paul Knapman added that in the early hours of that morning, "there was a gay orgy going on".
The count had denied witnessing any homosexual activity at the party. He and three other partygoers did not face any charges.
The count was in the news in 1986 over the death of Olivia Channon, daughter of Conservative minister Paul Channon, due to an overdose.
Her body was found on the count's bed at Christ Church College in Oxford.
Police are investigating the circumstances of the count's death and a post-mortem examination will be conducted on Wednesday.
