Prince Harry 'very concerned' about Kate Middleton

Prince Harry is said to be ‘very concerned’ about his sister-in-law Kate Middleton after the Princess of Wales sparked new fears for her health after cancer diagnosis last year.

The Radar Online, citing royal insiders, has revealed that Archie and Lilibet doting father ‘worries Kate might be struggling more than people realize.”

The royal sources further said, “He knows she’s the type to put on a brave face no matter what she’s going through, so of course he's very concerned."

The future queen sparked concerns by skipping the annual Royal Ascot horse racing event, four days after the future queen appeared on the Palace balcony for Trooping the Color alongside husband Prince William and their children Prince George, Princess Charlotte and Prince Louis.

According to the publication, the Princess of Wales was initially cited in the carriage list for Ascot's Royal Procession on June 18, but her absence was announced at the 11th hour.

The insiders have disclosed that Kate was "disappointed” to miss Royal Ascot, but “has to find the right balance as she fully returns to public facing duties."

The source tells the media outlet, the Princess of Wales "knows she should not overdo things," adding, "Things have not been plain sailing."
