While King Charles has been out of the spotlight as he is treated for cancer, Queen Camilla has continued a packed schedule

Queen Camilla is taking some time out.

After an intense period in which she has been helping care for her husband, King Charles, amid his cancer diagnosis and stepping up on his behalf at some royal outings, she is taking a break from royal duties this week.

The Queen, 76, regularly schedules a break around this time of year, palace sources point out to PEOPLE. One source says that it is a scheduled week of private time which is usual for her at this time of year and points out that it is not connected to King Charles’ health.

Queen Camilla’s next scheduled royal occasion will be when she leads the family, in the monarch’s place, at Westminster Abbey in London for the annual Commonwealth Day service on March 11. The King is expected to give a video address which will be played at the service.

Queen Camilla’s time off means that three out of the four most senior members of the royal family are out of the public eye. King Charles, 75, canceled most public-facing duties as he undergoes cancer treatment, although he continues to work behind the scenes.
