King Charles will join Queen Camilla and other members of the royal family for Easter service at Windsor Castle’s St George’s Chapel on Sunday

King Charles III and Queen Camilla will attend the Easter Sunday service at St George’s Chapel at Windsor Castle this weekend, Buckingham Palace confirmed today.

Royal aides also announced this morning that the couple would be “joined by other members of the Royal Family,” although no further names were given.

The decision for Charles to attend will be seen as significant as it suggests the King’s doctors are happy for him to attend an event despite his cancer treatment.

The couple will attend the Easter Mattins Service — as it is officially known — which will last an hour from 10:45 a.m. to 11:45 a.m., according to the chapel’s website.

The service will be preceded by Holy Communion from 8:30 am to 9:00 am. There will also be a Eucharist from 12:00 to 12:45, followed by a song from 3:30 to 4:15.

The king has been treated for an unknown form of cancer since early February, after undergoing surgery for an enlarged prostate at the London Clinic.

The confirmation comes four days after Charles’ daughter-in-law Kate revealed she had been diagnosed with cancer and was undergoing preventive chemotherapy.

William and Kate will not attend the service, which is unlikely to be a major family gathering or service, as Charles has suspended royal duties to the public.

William is expected to return to public duties after his children return to school after the Easter holidays. For now, he will continue to balance supporting his wife and family with carrying out his official duties, as he has done since her surgery in January.
