BBC quiz show host Victoria Coren Mitchell has blasted Meghan Markle critics and said her new Netflix show is going to be "box-office gold".

The Duchess of Sussex made headlines earlier this month when she appeared in the trailer for her new Netflix show.

With Love, Meghan was due to be released on Wednesday but was postponed until March 4 following the latest wildfires in Los Angeles.

Meghan's trailer came amidst reports that the Sussexes's Netflix deal is nearing its end in 2025, with several royal commentators questioning whether the streaming giant would renew it.

But according to the Only Connect host, Netflix cannot be "worried" about its deal with Harry and Meghan, as her latest show is going to be a big hit.

Ms Coren Mitchell wrote in her column for the Telegraph: "Everybody says that Netflix is worried about its deal with Prince Harry and Meghan Markle, but I don’t think it can be because Meghan is box-office GOLD.

"I’m not being sarcastic. She absolutely is. I know, I know, you haven’t.

"You haven’t watched the trailer and you’re not interested in her cookery show and you thought it was all a ridiculous fuss when Princess Diana died and you much prefer the Duchess of Gloucester who can walk all the way round a room without anybody noticing and that’s much better."

But she hit back at Meghan's critics and claimed she is "astonishingly interesting".

She explained: "You're both wrong because she’s astonishingly interesting and everybody knows that except you. Prince Harry, God bless him, is not. Fame doesn’t suit him, in both senses of that term.

"In the meantime, Meghan remains compellingly watchable, Harry the opposite, and in both cases for the wrong reasons."

She added: "I tuned in to Meghan’s cookery show trailer as soon as I heard about it.

"It smells quite strongly of “playing shop”; it’s derivative, it feels inauthentic, and is certainly another in that long history of mixed messages (“Come hither! Go away!”).

"Yet a watchable awkwardness arises; she’s got something. I won’t watch the whole upcoming series, and I might watch the bits I watch with something like horror, but horror isn’t boring."

The TV host concluded: "One day, if this TV career is to continue, perhaps Harry and Meghan will make a really truthful portrait of who they are, what they want and how their different instincts clash together. I’ll be here.

"I think that might make one of the greatest reality shows of all time."
