Prince Harry, Meghan in New Palace Briefing War Over Baby Lilibet Tribute to the Queen

Prince Harry told Queen Elizabeth II he and Meghan Markle hoped to call their baby Lilibet before the official announcement, their spokesperson has told Newsweek.

The rare official intervention comes after a palace source told the BBC the queen was "never asked" for permission to use the nickname she has had within the family since childhood.

However, Newsweek has been told the Duke and Duchess of Sussex would not have gone ahead with Lilibet if the monarch, 95, had not been supportive.

Harry and Meghan's spokesperson told Newsweek: "The Duke spoke with his family in advance of the announcement, in fact his grandmother was the first family member he called.

"During that conversation, he shared their hope of naming their daughter Lilibet in her honor. Had she not been supportive, they would not have used the name."

The queen was first nicknamed Lilibet by her father when she was a child and could not pronounce "Elizabeth."

However, it stuck through to later life and was famously used by husband Prince Philip.

Harry and Meghan's spokesperson said in their official announcement on Sunday that their baby's name was a tribute to the monarch.

Lilibet Diana Mountbatten-Windsor was born on Friday, June 4, at 11.40am local time in Santa Barbara.
