Although Prince Charles has spent the last few years taking on more responsibilities in preparation to become king, the Prince of Wales made a major mistake in the past that embarrassed Queen Elizabeth.

In 1999, Charles was scheduled to appear at a state dinner at the Chinese embassy in London, but he never showed up for the event. The decision appeared to be Prince Charles’ way of making a political statement against the Chinese President, who attended the gathering

In the Channel 4 documentary “The Royal House of Windsor,” royal reporter Richard Kay claimed the move showed Charles’ support for the exiled spiritual leader of Tibet, the Dalai Lama.

“By not attending on this occasion, he was not only letting down the monarchy, he was embarrassing his mother,” Kay explained.

“Those who work for the Prince of Wales didn’t have an explanation other than that he had an unbreakable arrangement elsewhere,” the commentator added.

By snubbing the state dinner, Prince Charles was essentially jeopardizing the diplomacy between the labor government and the royal family. “The monarchy was expected to put on a show,” Kay revealed.

“We were trying to foster good trading relations with China, and in order to do that, all parts of the state system has to work smoothly. And the Royal Family, as ever, had a big part to play, they were really rolling out the red carpet.”

Kay revealed that members of the royal family arrived at state dinners in ascending order of who is the most important, with the Queen arriving last. However, when Queen Elizabeth arrived at the event the palace realized Prince Charles backed out of the dinner.

“There absolutely was an expectation that Charles would be there. And the way that the royals arrive at these banquets, the Queen is the last to arrive, so Charles would have been the second last to get there,” Kay shared.

“And when the car came and it was the Queen getting out, of course, we realized we had a big story here because the Prince of Wales wasn’t there. There was no explanation for it, the Palace didn’t brief on it. I think they were caught unawares.”

Members of the royal family typically stay politically neutral and don’t make opinionated statements about political issues in other countries. However, Prince Charles’ absence at the dinner showed where he stood on the matters in China.

“Having a significant figure like the Prince of Wales, heir in line, signal his disapproval of what’s going on in Beijing was damaging in the extreme,” Kay revealed.

“Buckingham Palace’s response was one of anger – so angry, in fact, that some of their senior officials briefed journalists about what they described as a ‘petulant and selfish’ prince.”

Instead of attending the dinner, the Prince of Wales was busy hosting a small dinner party with Camilla Parker Bowles. After years of being molded to take the throne, nowadays, Prince Charles typically remains politically neutral amid global issues.
