Queen Camilla is mourning the loss of a close family member who joined her and King Charles on their honeymoon.
It has emerged that her brother-in-law Simon Elliot, the husband of her sister Annabel, has died at the age of 82.
The businessman and landowner was married to Annabel for 50 years with the couple extremely close to the Queen Consort as well as the King.
Their closeness even meant the couple joined Charles and Camilla on their 2005 honeymoon in Balmoral after their Windsor wedding and he was also a guest at the late Queen's funeral back in September.
According to The Sun, Mr Elliot died several days ago with his funeral due to take place later this month in Stourpaine, Dorset.
He and wife Annabel, an interior designer, had three children, daughters Catherine and Alice and son Mark, who is a former co-chairman of the Conservative party.
His death comes just months after Camilla's cousin Charles Villiers was found dead aged 59 in a hotel in the Marylebone area of London last August.
In 2014, Camilla also lost her brother Mark Shand suddenly after he suffered a fall while on a night out in New York City.
News of her brother-in-law's death comes as the Queen Consort hosts a reception at Buckingham Palace today to mark International Women's Day.
She has invited inspiring women from across society, including entrepreneurs, entertainers, athletes, authors, journalists and public servants to the event.
And earlier, she released a message to mark the day, which said: "International Women's Day is a day to celebrate female achievement, to encourage and inspire one another and to thank the women in our lives for their contribution to society."
Meanwhile, yesterday, Camilla joined Charles for a visit to Colchester, where they celebrated its recent city status.
Camilla was presented with a membership card for Essex libraries during a tour of the Colchester branch with the King, as she celebrated the Essex Year of Reading with broadcaster and children’s author Dermot O’Leary and screenwriter Frank Cottrell-Boyce.
The Queen Consort, who supports a number of literacy charities, joked: “I shall have to come back and see what I can find,” following the presentation.
She enjoyed a reading from Alice In Wonderland by actors from the local Mercury Theatre in costume as Alice, the Mad Hatter and the March Hare.
