King Charles and Queen Camilla will attend this week's Easter Sunday service, in what will be the monarch's first official public outing since his cancer diagnosis.
GB News can confirm the monarch and his wife will be attending the religious service at St George's Chapel in Windsor this weekend.
Other members of the Royal Family are expected to join King Charles, 75, and Queen Camilla, 76, at the Easter service.
However, Princess Kate and Prince William will not be attending, following the Princess of Wales announcing her own cancer diagnosis.

The couple and their three children, Prince George, 10, Princess Charlotte, eight, and Prince Louis, five, will not be attending.
Last week, the Princess of Wales revealed she was undergoing a course of preventative chemotherapy for cancer.
In a video message, she said: "In January, I underwent major abdominal surgery in London and at the time, it was thought that my condition was non-cancerous.
"The surgery was successful. However, tests after the operation found cancer had been present.

The Princess of Wales continued: "This of course came as a huge shock, and William and I have been doing everything we can to process and manage this privately for the sake of our young family.
"As you can imagine, this has taken time. It has taken me time to recover from major surgery in order to start my treatment.
"But, most importantly, it has taken us time to explain everything to George, Charlotte and Louis in a way that is appropriate for them, and to reassure them that I am going to be ok."
