King attending church in Sandringham after cancer message

Last night the monarch thanked people for their “many messages of support and good wishes”.

Charles has been recovering from treatment in the privacy of the Sandringham estate since February 6.

He was seen smiling and waving while walking into the service at St Mary Magdalene Church this morning with Queen Camilla.

The church is closed to the public until around April and much of the estate is blocked off.

In yesterday's message to the public, Charles said: “I would like to express my most heartfelt thanks for the many messages of support and good wishes I have received in recent days.

“As all those who have been affected by cancer will know, such kind thoughts are the greatest comfort and encouragement.

“It is equally heartening to hear how sharing my own diagnosis has helped promote public understanding and shine a light on the work of all those organisations which support cancer patients and their families across the UK and wider world.

“My lifelong admiration for their tireless care and dedication is all the greater as a result of my own personal experience.

“Charles R.”

Buckingham Palace confirmed the King, who only acceded to the throne 17 months ago, does not have prostate cancer, saying only that he has a “form of cancer”.

He was diagnosed after a “separate issue of concern was noted” and was investigated while he was being treated for his benign enlarged prostate.

The Palace has called for the King’s privacy to be respected, especially during his treatment, but said he wanted to make his diagnosis public because of his long-running support for cancer charities.

Charles has postponed all public-facing duties, but is continuing with behind-the-scenes work on his red boxes of state papers.

The Prince of Wales may step in to represent his father at an event, but no engagements are scheduled at the moment and the royal palaces will make arrangements if the need arises.

The King’s illness coincided with a hospital stay by the Princess of Wales, who underwent an unknown but planned abdominal surgery.

It is thought the Prince and Princess of Wales are currently also in Sandringham, staying at Anmer Hall, their 10-bedroom home on the estate, for the half-term holiday.
