GB News host Isabel Webster pointed out that Queen Camilla and Kate Middleton share some "similarities" when it comes to supporting their husbands.
Speaking on Breakfast Royal commentator Angela Levin said: "I wrote her [Camilla's] biography and she's got this very strong instinct of knowing what is right at the right moment.
"The fact that she could take all the nastiness when they separated from Diana, that now she knows exactly what King Charles needs.
"She's been there so solidly with the work and the engagements, when you saw the picture of their 19th wedding anniversary that came out yesterday, you can see that they are so interactive together.
Isabel pointed out that the pair are quite similar

Isabel pointed out: "I think there's a lot of similarities between the Queen and the Princess of Wales. I think they're both such great partners for the King and Prince William, just temperamentally as well.

"They're very good in the background at supporting the leading man, and they're sort of quite stoical and I can see why actually both of them have chosen those leading ladies."
Levin added: "Which has obviously helped William get on better with his father. Camilla helped Catherine know what to do when she joined the Royal Family, she knew what the protocol was and how to help her.
"Catherine was very grateful, unlike Meghan, who she tried to help as well and was not interested."
Levin also pointed out that it is unlikely that Prince Harry will reconcile with his family when he makes his return to the UK next week for the Invictus Games.
Isabel said "it is easy to understand why they are both leading ladies"

"Meghan is going to go straight to Africa because she met the Nigerian group and she likes that, so he'll be whizzing off.
"He won't see anybody, but he's no longer very popular. For the last couple of years I have had lots of emails from people saying, can't you stop it?
