Appearing on Mail+’s Palace Confidential, Ms Vine said: “She is the antithesis of Meghan. There are echoes of Philip in Kate.
“She is in it for the long game, she does not expect any immediate reward”
Speaking about the work behind the scenes done by Kate over the past 10 years, since she officially joined the Royal Family, Ms Vine continued: “She has very slowly but surely built up her reputation – not just with the family, I think, but also with the public.
“And she is all about the duty and all about the family and trying to do what’s best for everybody.
“I think it contrasts so starkly with this sort of ‘me me me’ thing that Harry and Meghan have got going on, where everything is about their emotions, all of the time.
“I don’t know what Kate’s emotions are, I don’t need to know what Kate’s emotions are.
“She is very good – she sort of shows just enough to show that she is human and a normal person, relatively speaking, but then she maintains this… I think she is quite good at managing that dynamic between being a public persona and being a real person, a mother with three kids who likes to take photographs.
“She is all about show and not tell. She has really put in the work and I think that is starting to really pay off now.”
