Charles and Camilla shared a sweet tribute to Prince Philip
The poem read in part: "'The Patriarchs – An Elegy' by Poet Laureate Simon Armitage. Remembering His Royal Highness The Duke of Edinburgh on the first anniversary of his death. Find out more about his life and legacy via our link in bio.
"On such an occasion to presume to eulogise one man is to pipe up for a whole generation - that crew whose survival was always the stuff of minor miracle, who came ashore in orange-crate coracles, fought ingenious wars, finagled triumphs at sea with flaming decoy boats, and side-stepped torpedoes.
"Husbands to duty, they unrolled their plans across billiard tables and vehicle bonnets, regrouped at breakfast. What their secrets were was everyone’s guess and nobody’s business. Great-grandfathers from birth, in time they became both inner core and outer case in a family heirloom of nesting dolls."
Members of the royal family take part in Prince Philip's funeral procession
Philip died aged 99 on Friday 9 April 2021. Buckingham Palace made the announcement in an official statement that read: "It is with deep sorrow that Her Majesty The Queen has announced the death of her beloved husband, His Royal Highness The Prince Philip, Duke of Edinburgh.
"His Royal Highness passed away peacefully this morning at Windsor Castle. The Royal Family join with people around the world in mourning his loss. Further announcements will be made in due course."
Only 30 people were allowed to attend Philip's funeral at Windsor Castle due to COVID restrictions, but last month, a larger service of thanksgiving was held at Westminster Abbey that saw hundreds in the congregation, including the Queen and the royal family.
