“She knows the important role the family plays in building relationships globally on behalf of the UK.”
The insider added: “It is clear that she and the King are quite close — in some respects closer to him than William."
Noting Prince William and Prince Harry’s "fractious relationship" with their father, the insider also told People: "It’s only been recently that William has been closer [to Charles] — and Kate has acted as the honest broker in that."
