Prince William was "not impressed" by Harry and Meghan's attempts to keep the birth of their son Archie a secret, a royal author has claimed.

The Duke of Cambridge reportedly felt the efforts were "prima donna" and "did not think too highly" of the way the announcement was handled by the couple.

Archie arrived on May 6 2019 at London hospital The Portland – where many royals have been born over the decades including Princess Beatrice and the Cambridge's three children.

But in a huge break from tradition, the news that Meghan had gone into labour came at around 2pm when it was reported by Sky News.

Royal births are usually reported by the household, with all three of the Cambridge births being announced by the palace.

William's alleged disapproval was reportedly the reason behind him and Kate waiting a full eight days to visit the couple and their newborn, reports Birmingham Live.

Robert Lacey has written in his new book Battle of the Brothers – which is making headlines – about William's view.

"William did not think too highly of Harry and Meghan’s ‘prima donna’ manoeuvres to conceal the birth of their son in May 2019," Lacey wrote in his book.

"This impression was confirmed by the failure of William and Kate to visit the new arrival for a full eight days."

The couple said afterwards: "The Duke and Duchess of Sussex are pleased to announce they have named their first born child: Archie Harrison Mountbatten-Windsor.

"This afternoon Their Royal Highnesses introduced Her Majesty The Queen to her eighth great-grandchild at Windsor Castle. The Duke of Edinburgh and The Duchess' mother were also present for this special occasion."

Archie made his first public appearance in May of that year.

In her first public remarks since giving birth the duchess said: "It's magic, it's pretty amazing. I have the two best guys in the world so I'm really happy."

As her husband held their son, Meghan wore a white sleeveless wrap dress and added: "He has the sweetest temperament, he's really calm."

As they both laughed, Harry said: "I don't know who he gets that from."

Meghan added: "He's just been the dream so it's been a special couple of days."
