The Duke of Cambridge has revealed to students and benefactors that he was a lazy student during a visit to Oxford's Magdalen College to open a new library.
Speaking about his time at St Andrews University, he said: "I can't say I was a regular attender of libraries."
Dayna Hamilton, a third-year engineering student at Magdalen, was among those the Duke spoke with.
She said William claimed he would have gone more often if he had a library like Magdalen's £11 million refurbished one.
"He said if this was his library he would have gone a little bit more," she said.
William unveiled a plaque to officially open the recently renovated Longwall Library and received a copy of the book Hidden Magdalen from college president Professor David Clary.
He also spoke to students who were sitting at desks. But he was quick to realise that they were not really studying hard.
Jack Barber, 21, who is reading history at Magdalen and helped raise money for the refurbishment, said William spotted that his book had been placed as a prop for the visit.
"He saw my book and it was obviously the first one I plucked off the shelf.
"He said 'Enjoy your pretend studying'."
The college's previous library, a converted Victorian schoolhouse, was opened by William's great-great-uncle, Prince Edward, who went on to become King Edward VIII. Edward was an alumnus of Magdalen College.
William also met a student carrying a poster which read "Welcome William" and mentioned his Heads Together mental health campaign.
Katie Shepherd, 20, a biology student at the college, said that while the Duke was pleased to see a reference to the campaign, it showed that she had not been studying hard.
"He mentioned that I had spent more time doing this rather than work. He joked 'typical student'."
