Rumor has it that Prince Charles and Camilla Parker Bowles are on the verge of a split. Rumors started after the Duchess of Cornwall left ahead of Prince Charles while on their royal tour in New Zealand.

Prince Charles and Camilla went on their third royal tour of New Zealand last week. After spending days together in the country, Camilla returned to the U.K. on Sunday, leaving Prince Charles traveling alone to Tuvalu and the Solomon Islands.

Camilla’s departure came as a surprise for royal followers, especially since their five-day tour seemed to have gone smoothly. In fact, photos of the couple during their royal tour made the rounds online last week, showing the royal couple all-smiles throughout their trip. On their last day together, they even went to Christchurch to attend a mass.

As Camilla returned to Britain and rumors started to grow, Clarence House released an official statement to shed light on the issue. The statement revealed that Camilla’s departure was part of the plan—that the Duke and Duchess of Cornwall’s New Zealand trip would end with Camilla returning to the U.K. alone.

“At the end of the tour of New Zealand, the Duchess will return to the U.K.,” the statement reads. “The Prince will travel on to Tuvalu where he will receive an official welcome and attend a reception. His Royal Highness’ programme will focus on environmental issues and how local communities are responding to climate change,” the statement added.

Prince Charles is expected to meet young people in Tuvalu, where they will discuss the positive contributions that the youth are making to the climate change debate. Following his short trip to Tuvalu, the Prince of Wales will head to Solomon Islands. This trip will mark his first visit to the islands and the end of the royal tour.

Before their royal tour, Camilla opened up about her fear of flying. While Clarence House did not explain why Camilla could not accompany Prince Charles to the next leg of their royal tour, there are speculations that it could be because of her phobia. A single trip from New Zealand to Tuvula and the Solomon Islands takes around 20 hours in an airplane.
