Cancer-stricken King Charles laughs as Queen Camilla waves kindly as they are seen driving together to Sunday service at Crathie Kirk

Cancer-stricken King Charles beamed this morning as Queen Camilla waved kindly to well-wishers as they drove to the Sunday service at Crathie Kirk.

The couple had arrived at the late Queen’s beloved Balmoral estate in Aberdeenshire on Thursday for some R&R and to celebrate their 19th wedding anniversary.

The king’s arrival in Scotland marked the first visit to the country since he was diagnosed with cancer in February, sending shockwaves around the world.

Charles has largely stepped back from his public duties since revealing his illness, but he has continued to read his daily red boxes and hold his weekly audience with the prime minister.

The King has given a much-needed boost to the British public, who are still reeling from the Princess of Wales’ cancer diagnosis last month.

He appeared alongside other senior royals at the Easter Sunday service in Sandringham, shaking hands and chatting with royal fans who lined the nearby road.
