King Charles set to break tradition at Trooping the Colour amid cancer treatment

The monarch is determined to take part in his official birthday celebrations on June 15 but concessions will be made as he continues his cancer treatment, The Telegraph has reported.

For several weeks, Buckingham Palace and the Ministry of Defence have been exploring ways in which he can take part while avoiding any undue risk to his health.

The options included watching the ceremony from a podium, rather than on horseback, and being driven from Buckingham Palace in a carriage.

Buckingham Palace sources indicated it would be unlikely for the King to ride on horseback.

One said it was “most likely” Charles would travel via carriage, although insisted a final decision was yet to be made.

The King is also expected to join other senior members of the Royal Family on the palace balcony for the traditional RAF flypast.

Last year, the King took the salute as sovereign for the first time riding Noble, a seven-year-old black mare.

Noble was gifted by the Royal Canadian Mounted Police, following a tradition that dates back to 1904.

His Majesty prepared for the occasion by paying regular visits to his new mare at Windsor.

It was the first time the monarch had appeared on horseback at the event since Queen Elizabeth II last rode in 1986.

The late Queen rode the same horse, Burmese, for 18 years.

Trooping the Colour is one of the highlights of the royal calendar, with most members of the Royal Family attending each year.

The nature of the King’s involvement will depend on his health and medical advice.
