Like the late Queen Elizabeth II and Prince Philip, the current King and Queen are not ones for PDAs, but there have been some touching photographs of the couple over the years.
From hand-holding to kisses at the polo, Charles and Camilla have shown their deep affection for one another.

The Queen's sister Annabel Elliot described Camilla as Charles' "rock" in a special BBC documentary showing behind-the-scenes life in the run-up to the coronation last year.
Now look at the photographs that show the King and Queen's rare tactile side…
After confessing to an affair during his marriage with Princess Diana, Charles kept his relationship with Camilla largely private for years. One of the first times we saw the couple showing affection was in 2001 when Camilla – who was a patron of the National Osteoporosis Society – welcomed Charles to an event at Somerset House with a kiss on the cheek.
They may have avoided the traditional wedding day kiss, but the newlywed royal couple still looked cosy linking arms as they emerged from their civil ceremony at Windsor Guildhall in 2005.
Some may say Charles and Camilla were clinging onto one another for balance while making imprints of their feet at St Michael's Mount, but we like to think it was also a show of solidarity.
Affection comes in many forms, as Charles proved when he thoughtfully helped his wife fasten her protective face mask at Royal Ascot in 2021, amid the coronavirus pandemic.
It looks as though Charles automatically reached out for his wife's hand as they enjoyed a walk through the Botanical Gardens in Rio De Janeiro in 2009.
The royals were the picture of wedded bliss the month after they got married. They couldn't contain their smiles as they clung onto one another after losing their footing during a walkabout on the island of St Mary's in the Scilly Isles in 2005.
The King was a perfect gentleman as he carried out his duties at his son Prince Harry's wedding to Meghan Markle in 2018, offering his arm to not only Camilla but also Meghan's mother Doria Ragland.
Supporting one another during the tough aftermath of Queen Elizabeth II's death, King Charles put a loving arm on the Queen's back as they viewed floral tributes outside Buckingham Palace.
And when Charles and Camilla returned to the ship, this subtle PDA was captured by cameras.
