The Queen has "regretfully" pulled out of an Easter event next week.
She will be replaced by Prince Charles and the Duchess of Cornwall at the service at St George's Chapel in Windsor on April 14.
The move comes amid fears for the Queen's health, with Her Majesty forced to pull out of a string of engagements in recent months.
The 95-year-old monarch missed the Remembrance Day service last November after spraining her back, and was unable to attend more events this year after catching Covid.
It's the first time the Queen will be replaced by her son at the Maundy Day church service, which takes place every year.
