Zara Tindall appeared overjoyed to see her uncle King Charles back out and about on Friday, as he made a surprise appearance at the Royal Windsor Horse Show.

Heartwarming images show Zara pull the monarch in for a warm embrace and a kiss shortly after he arrived at the staple royal event. 

The King is in high spirits at the event, hosted in the grounds of Windsor Castle, and is undeterred by the wet and grey weather as he spoke to officials under the cover of umbrellas. 

Wearing a large parker coat to shield him from the elements, the 75-year-old monarch looked delighted to be at day three of the event – just three days after he returned to public-facing duties. 

It marks a further sign that the King’s health is improving and he is responding well to treatment, after being diagnosed with an undisclosed form of cancer at the start of the year.
