According to Princess Diana's former butler, Paul Burrell, the future of Britain's royal family rests on Kate Middleton.
If Kate ever decided to divorce Prince William, the royal family would collapse, Burrell believes.
Burrell said that the future is underpinned by Catherine Middleton, and everything is pinned up by her.
The former butler said Kate, who is Princess of Wales like Diana, represents the monarchy's future.
Burrell also mentioned that it is not an enviable position to be in.
Kate Middleton has an enormous responsibility, and everything rests on her.
Burrell compared Kate's role to that of Princess Diana, who was once considered the future queen.
The comments were made during Burrell's interview with OK Magazine.
Burrell's comments highlight the significance of Kate's role in the royal family and the expectations that come with it.
