OUR EXPERT’S VERDICT

WILLIAM and Kate are quite a traditional royal couple, but they have emphasised their informal side here. It’s an invitational, sociable pose where their eye contact and smiles invite us to share their happiness.

Kate poses nearest the camera holding a beaming baby Louis in a way that ensures he dominates the pose but this is also a very even-handed family unit in terms of status, with William sitting back with a very playful Charlotte and George.

They form a happy, relaxed looking family unit here, inviting the viewer to share in the fun.
