SUSSEX ROYAL: Another photo montage, starting with harry on stage in November. INSTA-STATS: 290,000 likes, a sterling effort for a post free from children and animals.

KENSINGTON ROYAL: This time it’s a montage, too, starting with William and member of the Shout team, with a separate video. INSTA-STATS: Only 121,000 likes for the pictures, but 670,000 views of the video. WINNER: KENSINGTON ROYAL (but only because of the video views).
