It has been widely reported that the King is keen to resume some form of public duties, despite his illness, after the announcement of his cancer diagnosis on February 6.

A Buckingham Palace statement was released following the King’s diagnosis in February.

It said: “During the King’s recent hospital procedure for benign prostate enlargement, a separate issue of concern was noted. Subsequent diagnostic tests have identified a form of cancer.

“His Majesty has today commenced a schedule of regular treatments, during which time he has been advised by doctors to postpone public-facing duties.

“Throughout this period, His Majesty will continue to undertake State business and official paperwork as usual."

The Palace added that the King was "wholly positive about his treatment and looks forward to returning to public duty".

The statement continued: “His Majesty has chosen to share his diagnosis to prevent speculation and in the hope it may assist public understanding for all those around the world who are affected by cancer.”
