The King is to return to public duties after undergoing a period of treatment and recuperation following his recent cancer diagnosis.
The monarch has been receiving care as an outpatient since early February, with doctors “pleased” with the progress made so far.
Buckingham Palace has confirmed that the King and Queen Camilla will make a joint visit to a cancer treatment centre next Tuesday where they will meet medical specialists and patients.
The visit will be the first in a number of external engagements Charles will undertake in the weeks ahead.
The King and Queen will also host Their Majesties The Emperor and Empress of Japan for a State Visit in June, at the request of HM Government.
The Palace has said that the King is still receiving treatment and that all engagements have been decided in close consultation with his medical team.
The forthcoming engagements will be adapted to minimise any risks to his recovery.
A picture marking the first anniversary of the crowning of the King and Queen on May 6 has been released, taken the day after their 19th wedding anniversary on April 10.
Kate, the Princess of Wales, is also receiving treatment after being diagnosed with cancer following major abdominal surgery.
It was announced in March that medical teams had recommended that Kate undergo preventative chemotherapy after the the operation found cancer had been present.
