The King has marked his first Mother’s Day since the death of the Queen by posting a touching picture of the pair on Instagram.
The image shows the King as a toddler standing on his mother’s lap as both beam for the camera.
Another photo shows the Queen Consort with her late mother, Rosalind Shand, who died in 1994.
Along with the pictures, the post is captioned: “To all mothers everywhere, and to those who may be missing their mums today, we are thinking of you and wishing you a special Mother’s Day.”
The Queen Consort’s mother suffered from osteoporosis for years before her death, as did her grandmother.
She is now an ardent campaigner to raise awareness of the disease and in 2019 she founded the Royal Osteoporosis Society describing the condition as “rarely diagnosed” and “seldom discussed”.
Last year she encouraged older people to “discover the easy steps that we can all take to improve bone health throughout our lives”.
The disease, which weakens bones and causes them to break more easily, affects around 3.5 million people in the UK.
Kensington Palace also marked Mother’s Day, posting a picture of the Princess of Wales and her three children sitting in a tree.
The image was captioned: “Happy Mother’s Day from our family to yours.”
Elsewhere on social media, the Royal Collection Trust posted a picture of the Queen Mother with her second daughter, Princess Margaret, as a baby.
The image shows the infant princess lying on a pillow as her mother gazes down at her, holding her hand.
It was taken in 1930 when Queen Mother was still the Duchess of York and the late Queen’s grandfather, George V, was still on the throne.
The news comes a day after it was revealed that the King’s grandchildren, Prince George, Princess Charlotte and Prince Louis, will take part in the procession for his coronation later this year.
The children are expected to join their parents, the Prince and Princess of Wales in a carriage behind Charles and Camilla who will travel in the Golden State Coach as they return to Buckingham Palace.
George will be nine and Louis will be five while Charlotte will turn eight just four days before the coronation.
