Prince Harry "does upstage William" but the royals need an upbeat "joyful ambassador" to put out to the world, Tina Brown said.

Tina Brown, the former editor of Vanity Fair, the New Yorker and the Daily Beast and the author of multiple books about the British monarchy, has some pretty scathing things to say about Meghan Markle and Prince Harry’s post-royal experiment.

Prince Harry was a "lamb to the slaughter" in relationship with Meghan Markle, the former magazine editor said.

Royal author Tina Brown said Meghan Markle is flawless at getting everything wrong. She had the worst judgement and though she has people whom she asks for advice, she does not listen to those and does what she thinks right and that is inevitably always wrong.

But actually, the thing about Harry is he’s very good at being Prince Harry. And that’s the tragedy of all of this, is that he is the most talented member of the royal family, without doubt, in terms of being a prince,

Tina Brown, founding editor of The Daily Beast, has said that “all of [Meghan Markle’s] ideas are total crap,” in an astonishing attack on the Californian royals’ judgement.

Meghan Markle has been promoting American Riviera Orchard since March, but royal expert Tina Brown thinks the business' failure to hit retailers is a reflection of the Duchess of Sussex's professionalism.
