In June, photographs of Prince Edward, Duke of Edinburgh, meeting Ukrainian troops completing military training in the UK were shared on social media, raising concerns about his health.
Some royal enthusiasts believed the younger brother had lost weight and seemed weak in the photos.
"I'm concerned about the Duke's health." "He appears to have lost too much weight," claimed a royal admirer.
"I hope The Duke of Edinburgh is in good health," added another royal family admirer.
New photos taken at an occasion on Monday show the Duke of Edinburgh looking considerably better.
The Duke of Edinburgh took the salute from the Royal Box at Edinburgh Castle.
Meanwhile, some royal admirers have pointed out that Prince Edward bears a strong likeness to his late father, Prince Philip.
