Camilla, Duchess of Cornwall

Camilla, Duchess of Cornwall

Britain's Camilla, Duchess of Cornwall will miss the penultimate day of her tour of Mexico.

The 67-year-old royal began her and husband Prince Charles' visit to the country on the weekend but is to miss out on the activities planned for their second last day as she's unable to fly because of sinus problems.

A spokeswoman for Clarence House said in a statement: "The Duchess of Cornwall will not be joining the Prince of Wales in Campeche today as originally planned as Her Royal Highness is feeling unwell with a sinus problem."

However, not wanting to waste the day completely, it's been reported Camilla will instead meet with expatriates employed in the country.

The spokesperson continued: "The Duchess is very sorry that she will be unable to go to Campeche today [05.11.14]. Instead she is hoping to meet more of the British Embassy staff in Mexico City who have been working on her visit."

And, it is likely the Duchess will reunite with her husband, Prince Charles, 65, and resume her royal duties for the final day of their tour.

They added: "Her Royal Highness hopes to carry on with the scheduled programme tomorrow [06.11.14]."

Prince Charles is thought to always have a doctor on hand during his travels and it's understood that the medical professional advised Camilla that boarding a flight to Campeche would aggravate her sinus pain.

Charles will now visit the Edzna Maya archaeological site near the town of Campeche on his own as well as carry out an engagement at a Women's Justice Centre that Camilla was scheduled to undertake.
