Prince Charles’ brother-in-law, the Duchess of Cornwall’s brother, 62-year-old Mark Shand, has died as a result of a serious head injury he sustained during a fall.
According to the BBC, he was in New York when the incident happened on Tuesday night.
“The duchess, the Prince of Wales and all her family members are utterly devastated by this sudden and tragic loss,” read a statement released by Clarence House, Prince Charles’ official residence.
He was described as a man of “extraordinary vitality, a tireless campaigner and conservationist”.
Mr Shand was chairman of the Elephant Family, a movement which exists to save the endangered Asian elephant.
In its statement, Clarence House said it was with “deep sadness” that it had to confirm Mr Shand’s death.
It said his “incredible work through the Elephant Family and beyond remained his focus right up until his death”.
The death comes as the Duchess of Cornwall and the Prince of Wales, currently understood to be in Scotland, prepare for a high-profile tour of Canada next month.
Mr Shand, the duchess’s only brother, reportedly slipped while lighting a cigarette and hit his head on the pavement outside an after-party for a charity event.
According to the New York Police Department, the emergency services picked him up where he fell outside the Rose Bar and took him to Bellevue Hospital, where he was pronounced dead on Wednesday.
Mr Shand married French actress Clio Goldsmith – the niece of billionaire entrepreneur Sir James Goldsmith and the cousin of Jemima Khan and Tory MP Zac Goldsmith – in 1990. They have a daughter together called Ayesha, aged 19.
