Just yesterday King Charles shared a tender hug with his niece Zara Tindall at the show.

Excited to get back to public duties, the 75-year-old monarch was beaming at the rain-soaked event, donning a smart camel trench coat and brown suit.

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

Charles was snapped tenderly 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 the track sidelines.

Charles 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 held at Windsor Castle.

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

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

His Majesty chose to make his public comeback by visiting a cancer hospital earlier on last week.

He spoke to staff and patients with Camilla, 76, on St George's Day.

As a patron of MacMillan Cancer Support, Charles wanted the visit to raise awareness of the importance of early diagnosis and highlight innovative research supported by Cancer Research UK, which takes place at the hospital.
