Kate Middleton develops toughness: 'Prepared to fight'

Princess of Wales Kate Middleton has "developed a toughness" behind palace doors, a royal expert has claimed amid reports she is undergoing training to become the next Queen.

Speaking to the Fox News Digital, royal expert Valentine Low claimed that the future queen has "developed a toughness" behind palace doors as she supports her husband Prince William.

The royal expert said, "She has this public image of being nice and smiley. But she is strong-minded, strong-willed, and prepared to fight for what she wants and what she thinks is right."

Another royal expert Richard Fitzwilliams says the Princess of Wales has good reason to develop thicker skin.

The expert explained, "The onset of a life-threatening illness can make a person tough,", referring to her cancer diagnosis last year.

He added, "When they have a clear goal, as Kate has, the maintaining of the monarchy and bringing up her family means the experience, although traumatic, can be used to advantage in the years ahead."

Richard Fitzwilliams continued, "Kate needed confidence as a public speaker, which she now has. She is a fashion icon, which she uses to enormous advantage. And she and William are so close, as their PDA clearly shows. They are the monarchy’s future. They work brilliantly as a team now, and they will continue to do so when William becomes king."
