“Her confidence signals are on the increase and she appears to be showing signs of being willing to take on some of the big hitters on the world stage in terms of promoting her causes, so she may be a Queen who uses her voice and her world audience for active good works and campaigns.”

Kate will become Queen Consort when her husband Prince William ascends to throne, after the death of his father, Prince Charles.

This means she will be crowned in a ceremony alongside William.
