I was stunned to see them there’: Witness claims he saw Prince William and Princess Catherine in Windsor on Saturday

Kate Middleton has reportedly been spotted looking “happy” and “healthy” during a trip to a local farm shop near her family home in Windsor over the weekend.

An eyewitness has reportedly spotted Princess Catherine looking “happy” and “healthy” during a trip to a farm shop near her Windsor home amid ongoing global interest in her wellbeing and whereabouts.

The witness claims he saw Kate with her husband Prince William as they browsed at the Windsor farm shop, about three kilometres from their family home Adelaide Cottage on the Windsor estate.

“After all the rumours that had been going round, I was stunned to see them there,” the eyewitness at the farm shop told The Sun newspaper.

“Kate was out shopping with William, and she looked happy and she looked well.

“The kids weren’t with them but it’s such a good sign she was healthy enough to pop down to the shops.”

The Princess of Wales has been out of public view since undergoing abdominal surgery in January and made her last major appearance during a walkabout on the way to church at Sandringham on Christmas Day.

Remarkably, Kate has only been caught by paparazzi two times in almost three months.

On both occasions the Princess was photographed at a long distance and seated inside a car, prompting concern for her wellbeing following her major surgery, the details of which the royal has chosen to keep private.

Speculation about Kate’s health went into overdrive last week after the first official photograph released since her surgery was “𝓀𝒾𝓁𝓁ed” by major photo agencies who claimed the image was manipulated.

Kate publicly claimed responsibility for the photo debacle the following day and admitted in a statement to experimenting with “editing tools” on the photo.

The Princess, 42, is not scheduled to return to her duties until at least after the Easter break but is reportedly considering joining the rest of the royal family at church on Easter Sunday to reassure the public of her wellbeing.

“She and William are at their most open when out interacting with the public,” a source close to the Prince and Princess of Wales told the same newspaper.

“I can see a world in which the Princess might discuss her recovery out on engagements.

“If she was going to do it, that’s how she would do it.

“They appreciate the public’s love and affection for their children and know there is a public appetite to see them on their birthdays.”
