"She said it was just lovely and that it was her favourite photo of the tour,” said Simon, adding that he presented the couple with a black and white version of the picture at the end of their time in New Zealand.
"There was a bit of a plan for a [staged] family photo," he added. "But it fell to pieces because they allowed George to sleep for an extra half-hour."

The photographer also said that he plans on sending framed copies of the precious photo to Prince Charles and Queen Elizabeth.
