While attending a state banquet at Buckingham Palace on Monday,President Donald Trumpput his hand onQueen Elizabeth‘s back, sparking debate on whether or not he broke royal protocol.

The incident took place after Trump, 72, praised the Queen, 93, as a “great woman” for her work during World War II.

“From the Second World War to today, her majesty has stood as a constant symbol of these priceless traditions,” Trump said of the Queen at the dinner.

“She has embodied the spirit of dignity, duty and patriotism that beats proudly in every British heart,” he added.

The Queen alsospoke of her respectfor the U.S. saying in her speech, “Tonight we celebrate an alliance that has helped us to ensure the safety and prosperity of both our peoples for decades, and which I believe will endure for many years to come.”

In response to the back-patting gesture, the Queen didn’t appear ruffled.

Theroyal family’s websitestates, “There are no obligatory codes of behavior when meeting The Queen or a member of the Royal Family, but many people wish to observe the traditional forms.”

If an individual wishes to observe the traditional forms, it is advised that men perform a “neck bow (from the head only)” while women do a “small curtsy.”

“Other people prefer simply to shake hands in the usual way,” the website states.

In addition, the Queen should be addressed as “Your Majesty” upon presentation, and subsequently as “Ma’am.”

Obama, 55, later commented on the incident in her bookBecoming, writing, “If I hadn’t done the proper thing at Buckingham Palace, I had at least done the human thing.”

“I daresay that the Queen was okay with it, too, because when I touched her, she only pulled closer, resting a gloved hand lightly on the small of my back,” she added.
