Princess Anne: 'King Charles won't change'

STORY: In a video interview released on Monday (May 1) with Canadian news program "The National,, the daughter of late Queen Elizabeth II discussed the kind of monarch the King will be.

"I don't think he'll change. You know what you're getting, because he's been practicing for a bit," she said.

"He is committed to his own level of service, and that will remain true."

The 74-year-old monarch, who will be formally crowned on Saturday (May 6), is the oldest sovereign to take the throne in a lineage that dates back 1,000 years when he succeeded his hugely popular mother Queen Elizabeth after her death last September. She had reigned for 70 years.
