Meghan Markle “copyrighted” the name Lilibet before giving birth to her daughter, a royal expert has claimed.

They also blasted Prince Harry and Meghan Markle after a new royal book alleged that the late Queen Elizabeth was left furious following their claim she had given them her blessing to call their baby daughter Lilibet.

Lilibet was first used by the late monarch when she was just a toddler and unable to pronounce her own name properly. Her grandfather King George V would call her Lilibet imitating her own attempts to say Elizabeth and that’s how the name stuck.

Charles III: New King, New Court, The Inside Story by Robert Hardman, segments of which have been serialised by the Daily Mail, read: “One [aide] privately recalled that Elizabeth II had been ‘as angry as I’d ever seen her’ in 2021 after the Sussexes announced that she had given them her blessing to call their baby daughter ‘Lilibet’, the Queen’s childhood nickname.”

Reports at the time claimed the late Queen was consulted about the name, but did not feel able to say no whereas the BBC reported that a Palace source alleged the monarch was not asked by the Sussexes whether they could use the name.

At the time, the Sussexes’s lawyers reportedly sent legal letters to the BBC and other publishers saying the claim was false and defamatory, while their spokesperson insisted they spoke to the late monarch.

According to Hardman, Queen Elizabeth allegedly told Palace aides: “I don’t own the palaces or the paintings, only my name, and now they’ve taken that.”

Royal biographer Angela Levin blasted the couple over leaving the late Queen ‘furious’ and called their actions “appalling”.

She told GB News: “That’s an incredibly sad comment, I think one of the reasons she felt that way was because it was discovered that Meghan, even before Lilibet was born, had taken out the names officially so that she could use them to buy things and to identify them.

Presenter Eamonn Holmes asked: “What do you mean? They’d copyrighted the name?” Levin replied: “Yes. Before she had Lilibet, I think that was awful for the Queen because she gets drawn into owning organisations due to the name being so unique.

“This name is just for her because she couldn’t say Elizabeth when she was young. It’s also for her family, her parents, and the Duke of Edinburgh, they all called her it out of love, it’s very intimate.

“People who don’t know about that will think that the Queen is supporting this, let’s buy it. I think it’s appalling.”

Buckingham Palace and the Duke and Duchess of Sussex have been contacted for comment.
