Britain's King Charles is to make his most significant public appearance since he was diagnosed with cancer when he attends church on Easter Sunday.

Charles, 75, will join his wife and other members of the British royal family at the annual Easter Mattins Service at St George’s Chapel at Windsor Castle this weekend.

William, Kate and their children George, Charlotte and Louis will not be present.

The family are spending the Easter holidays together as they adjust to Kate’s cancer diagnosis.

Confirmation of Charles' appearance comes just four days after Kate released an emotional video message revealing she has started a course of preventative chemotherapy.

Post-operative tests following her major abdominal surgery showed she had cancer.

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

Charles 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, Charles and Camilla 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.
