Charles, the Prince of Wales, was born on November 14, 1948.
The black and white image taken by Chris Allerton shows the infant royal in his baptism robes. It comes a day after it emerged that Harry, his wife Meghan and Archie, would not be spending Christmas with the Queen at Sandringham.
A spokesperson for the couple told Sky News that the couple were “looking forward to extended family time” at the end of the month.
It is not yet known where they will be for Christmas, but the spokesperson said the decision “has the support of her majesty the Queen”.
