Buckingham Palace made an announcement in February which shocked the world - King Charles had cancer, and would be stepping back from public duties to receive treatment. Incredibly, just six months on, he is now considered fit enough to travel 10,000 miles for the upcoming royal tour of Australia and Samoa in the autumn. Courtiers have been clear from the start that there would not be regular updates on the health and recovery of the monarch - only when any major developments needed to be revealed. Now, insiders are shedding some light on what the King's path to recovery has looked like.
