“George, six, in tartan trousers and a white shirt, shares a red-carpeted step with grandfather Charles, 71.

“William, 37, stands behind his father, son and grandmother in a dark suit and tie.

“The first portrait of the quartet was released in 2016 to mark the Queen’s 90th birthday.

“It was then reproduced on commemorative stamps,” the report said.

“Both images were taken by Ranald Mackechnie.The latest official portrait comes just two weeks after the royals marked the festive season with a series of informal photos.
