Cancer-stricken King Charles is 'turning the dial' towards resuming his ordinary royal duties as he attends Easter service on Sunday for first public appearance in two months that is a 'sign of things heading in the right direction'

King Charles is said to be 'turning the dial' towards resuming his ordinary royal duties as he is set to attend the Easter service on Sunday, in what will be his first public appearance in two months following his cancer diagnosis.

A palace source told The Telegraph that the King's planned attendance at the service in St George's Chapel, Windsor, is a 'sign of things heading in the right direction'.

Charles and Queen Camilla will go to the Easter Matins Service - as it is officially known - which will run for one hour from 10.45am until 11.45am, according to the chapel.

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 Prince and Princess of Wales and their children George, Charlotte and Louis will not be there as they spend the holidays together after Kate's cancer diagnosis.

Aides have reportedly said that His Majesty's attendance at any event is 'to be hoped for and planned for rather than assumed', as he continues to focus on his health. 

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.

It comes a week 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 while 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.

It is not known how long Kate will be receiving treatment but it is understood she may be keen to attend events as and when she feels able to, in line with medical advice, although this will not indicate a return to full-time duties.

Charles's Easter Sunday engagement will be seen as the King making a move to reassure the public following the shock news.

The King is still undergoing treatment for cancer himself, but has been carrying out low-key official duties behind palace walls.

Although the Easter service is within the grounds of the castle, the King and Queen will be seen arriving, and are often watched by staff living at Windsor, who usually gather on a grassy bank nearby or watch from their doorsteps.

At last year's service, the King and Queen attended along with Princess Anne, Prince Andrew, Prince Edward, Sophie and Vice Admiral Sir Timothy Laurence.
