The King is "raring to go" and "supercharged his diary" as he has cancer treatment, says a palace source.

Charles was snapped embracing niece Zara Tindall, a former Olympian horse rider, in his third royal engagement this week.

He also cracked jokes and laughed with horse riders on track sidelines.

Charles has joined the event just like his mother used to.

The late Queen would regularly turn up as a spectator at the horse show which is at Windsor Castle.

Buckingham Palace will also announce a redistribution of the late Queen and Prince Philip's patronages.

The Royal Patronage Review concluded in time for the first anniversary of the Coronation on Monday.

Charles was last spotted, with Camilla by his side, on Sunday at Crathie Church service in Aberdeen.

It is the first time the pair have been spotted since Buckingham Palace revealed the King would be returning to public-facing duties.
