PRINCESS Kate made a triumphant return to royal duties yesterday as she greeted the Qatar Royal Family in London.

People were quick to comment on the flawless moment, with one saying: “I have missed her perfect curtsy a lot .”

Another agreed, saying: “LORD so perfect and effortless, UK is so lucky to have them.”

A third commented: “Same here. Perfect.”

Royal etiquette means that all royals are expected to bow or curtsy to the reigning monarch.
