King Charles has famously emphasized a "slimmed-down" monarchy, aiming to have fewer senior working royals. His sister, Princess Anne, doesn't think that's a great idea.

In a new interview with CBC News ahead of Charles's coronation, the Princess Royal said, "it doesn’t sound like a good idea from where I’m standing. I’d say I’m not sure quite what else we can do."

She said, laughing, "I think the slimmed-down was said in a day when there were a few more people around—make that seem like it was a justifiable comment."

Princess Anne will have a key role this weekend at her brother's coronation: she will reportedly be the Gold-Stick-in-Waiting, a bodyguard in the Royal Household. In the procession, the Princess Royal will follow on horseback behind Charles and Camilla in the procession from the Abbey to Buckingham Palace.

Elsewhere in the interview, Anne said of King Charles, "You know what you’re getting because he’s been practicing for a bit. I don't think he'll change." She added that he is "committed to his own level of service, and that will remain true."

She also responded to a question about Canada's relationship with the British monarchy, saying, "I think it's perfectly true that it is a moment when you need to have that discussion. But I would just underline that the monarchy provides—with the constitution—a degree of long-term stability that is actually quite hard to come by any other way."
