Duke and Duchess of Cambridge openly ‘flirting’ and ‘showing more affection’ – pictures

She added: “So far we’ve only seen some gentle back-touching, primarily with Kate touching William’s back, but here there is some much more intimate hand-touching. 

“Laughing at her husband, Kate also places her hand on his in a gesture of playful encouragement. 

“There’s an air of one-up-woman-ship about this whole scene, as though the hand-touch is Kate’s way of daring William to try the food too. 

“But the ritual is also hugely flirtatious as well.” 

Judi continued: “When the couple both hold a glass they seem to use the fact they both have a hand on it to indulge in some finger-touch flirting, too.
