The Duke of Westminster, Gerald Cavendish Grosvenor, passed away aged 64 in August. He suffered a heart attack while at Abbeystead Estate and was later taken to hospital in Lancashire, where he died. A spokeswoman from Preston coroner's office confirmed that there would be no inquest as he died of natural causes.

The Duke was a close friend of the royal family. His widow Natalia is Prince William's godmother, and his son Hugh, 25, is godfather to Prince George. The royals sent private messages of condolences when they learned of the Duke's passing.

He was estimated to have a fortune of £8.3 billion by Forbes, making him the world's 68th richest person, and the UK’s third. His vast wealth comes from estates in Oxford, Cheshire, Scotland and London; he owned 190 acres in Belgravia, one of London's most expensive districts.

Three days after his death, a private funeral service was held for his close family. The Grosvenor Estate released a statement, confirming: "A quiet private funeral service, attended only by close family members, was held this afternoon, Friday August 12, for the Duke of Westminster who died on Tuesday August 9 2016."

A short eulogy was also posted on the Grosvenor website, which read: "He was a passionate country man, committed soldier, an excellent shot, a true entrepreneur and, importantly, he went out of his way to be courteous and humorous with all people, regardless of status or wealth.

"Distinctly down-to-earth, the Duke of Westminster was rarely seen without a Diet Coke and a cigarette (later electric). Not much of a sleeper, one might expect emails from him at any hour of the night and an average week would see him up and down from home in Chester to London and all over the world to visit soldiers, businesses, charities and rural estates while representing and promoting numerous organisations."
