Over the weeklong India and Bhutan trip that Prince William and wife Kate Middleton enjoyed recently, royal fans saw very little sweet moments between the couple. A new report has now explained why the royal couple did not even hold hands in public.

The Duke and Duchess of Cambridge spent several days enjoying the culture and interesting locations of India and Bhutan. Prince William and Kate met the locals, interacted with children, as well as rubbed shoulders with politicians, businessmen and celebrities. They even enjoyed a few quiet moments when they visited Gandhi’s memorial, took a trek in Bhutan and witnessed the grandeur of the Taj Mahal.

However, the royal couple was rarely seen holding hands or being sweet with each other. A report posted on People magazine has cited several reasons why fans saw very little PDA. Royal etiquette expert, as well as founder and director of Beaumont Etiquette, Myka Meier, shared that it was no surprise that the royal couple looked aloof in some pictures.

She explained that there is “no actual etiquette or royal protocol” that indicates married members of the royal couple should refrain from showing displays of public affection. Meier reportedly said that the Duke and Duchess of Cambridge may have likely refrained from showing sweet moments given that they were technically “working representatives of the British Monarchy” during the recently concluded royal tour to India and Bhutan.

"The couple are likely to show very little PDA, if any, to remain professional during their designated roles abroad,” she added.

Royal writer Judy Wade also told People magazine that the couple likely refrained from holding hands in locations such as the mausoleum. “[It] is very much an official, straight-laced kind of event and you wouldn't hold hands there if they're there on an official visit,” she explained.

William and Kate recently wrapped up a jam-packed visit to India and Bhutan. The royal couple topped off their tour with a trip to the iconic Taj Mahal. India’s famed tourist spot has been described as a “place heavy with symbolism for the prince,” as stated in a Wall Street Journal report.

The royal prince’s mother, the late Princess Diana, previously posed on a bench with the Taj Mahal in the background during a trip 24 years ago. The royal couple also posed on the same bench during their recent visit.
