Since the Duke of Sussex’s divisive memoirs went on sale, the Prince and Princess of Wales haven’t participated in a public event.
As they formally launched Royal Liverpool University Hospital, William and Catherine waved to onlookers.
Spare, the autobiography of Prince Harry, sold more non-fiction books than any other book in history.
The book contains accounts of the tense bond between Prince Harry and his older brother.
When a reporter questioned the couple at the hospital entrance, “Were you offended by the comments in Harry’s book, sir?” they remained silent.
The prince was at an appointment when an 81-year-old woman grabbed his hand and told him, “Keep going Will, Scousers adore you. I will do.”
The prince and princess later met medical personnel at the facility, which is now the largest hospital in Britain to provide all patients with ensuite rooms.
Nikki Langley, an employee who works in administration, was thrilled when a smiling William posed for a selfie with her and her three coworkers, the five cramming themselves into the picture.
A short while later, the princess joked, “I’m going to get told off by William,” as she asked Kate for a picture.
The 646-bed facility began accepting patients in the fall, replacing the previous Liverpool Royal Hospital.
Due in part to the failure of the construction company Carillion, it was delayed by five years, and the expenses rose from £335 million to an estimated $1 billion or more.
