King Charles III could be set to make his first state visit to the US, but one royal expert believes the British monarch may need a break from the U.S. President.

After hosting Donald Trump for three days during his recent state visit, King Charles may be hopping on a plane to visit the US.

Reports indicate that President Trump’s state visit to the U.K. went so well that he’s considering extending an invitation to Charles and Camilla for their own state visit to the US. While this might sound thrilling for royal watchers, one expert suggests it might not be as exciting for the royals themselves, as they may like a break from Trump.

Speaking exclusively to Mirror U.S., royal expert Pauline Maclaran, a professor at Royal Holloway, shared her initial thoughts on the British monarch potentially making a state visit to the US.

Maclaran said: “My first thoughts, poor Charles, having to show off his diplomacy again, potentially – just when he thought he could relax a bit, probably.”

When asked if Trump would follow through on this, Maclaran said it might depend on his mood. Maclaran explained: “It’s very hard to predict Trump, and it will certainly depend on how he’s feeling nearer the day.”

President Trump is known for his fondness for the Royal Family and wouldn’t pass up a chance to mingle with the royals, a point Maclaran expanded on. “My guess is he will not be able to resist another occasion to feature himself playing a starring role in the pomp and pageantry, although of course, this will not be as evident or colorful as it was in England,” she said.

“However, the visit will certainly attract much attention and Trump loves that,” Maclaran noted. Another expert suggested the king should accept, arguing we must “stand together.”

Brittani Barger, co-founder of Royal News, argued that saying yes would maintain the frequently discussed “special relationship” between the nations. “I would think the King would accept it as it is a great way to keep the special relationship between the U.S. and UK,” she stated. “In times such as these, it’s important that we stand together.”

Should the British monarch be unable to make the trip for any reason, sources say Prince William and Princess Kate would step in and reduce it to an official visit instead. “I think the only way Charles would decline the invite is for health reasons,” Barger said.

“The visit might be altered so that the Prince and Princess of Wales could come in his place, of course, if the Princess’s health allows. In that case, it would just be an official visit and not a state visit,” the expert added.

The last state visit by a monarch was Queen Elizabeth II in 2007. The late Queen made four state visits during her reign, meeting with Presidents Dwight D. Eisenhower, Gerald Ford, George H.W. Bush, and George W. Bush.
