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

Royal aides also revealed this morning that the couple would be ‘accompanied by other members of the Royal Family’, although no further names were given.

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

The couple will go to the Easter Mattins Service – as it is officially known – which will run for one hour from 10.45am until 11.45am, according to the chapel website.

The service will be preceded by holy communion from 8.30am until 9am. There will also be a said eucharist from 12pm to 12.45pm, then evensong at 3.30pm to 4.15pm.

The King has been receiving treatment for an undisclosed form of cancer since early February after he had an operation for an enlarged prostate at the London Clinic.

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

William and Kate will not attend the service, which is unlikely to be a large family gathering or service because Charles has paused public-facing royal duties.

William is due to return to public duties after his children return to school following the Easter break. For now, he will continue to balance supporting his wife and family, and maintaining his official duties as he has done since her operation in January.
