Princess Diana's astrologer has revealed the star signs of members of the Royal Family and the personality traits they indicate.

Debbie Frank was personal astrologer to the Princess of Wales from 1989 onwards and is world-renowned for her work.

The prolific media astrologer provided readings for high ranking members of the royal family in today's Mail on Sunday, which claims Meghan Markle is a 'born leader' but Kate Middleton is a 'safe pair of hands.'

In describing the Duchess of Sussex, she wrote: "Meghan is very true to herself and her own sense of identity. Her chart shows the Sun in Leo - which is all about being a brand.

"Leos are the queens of the zodiac, and Meghan is a born leader. Leos are passionate people, and we see that in how Meghan uses her voice and profile."

A Leo is represented by the lion and falls on the dates July 22 – August 22. Meghan's birthday is on August 4.

But it is believed Meghan's strong character could be why she has clashed with the Royal Family.

Although some royal experts believe she is what we need to modernise the monarchy as before the couple married, Sarah Sahagian wrote in the National Post: "If anything can make The Royal Family relevant in the 21st century, it just might be Meghan Markle.

"She is the articulate, progressive voice we deserve from a modern monarchy."

However, the Duchess of Cambridge, who is a Capricorn as her birthday falls on January 9, was described in the piece as having "dignity, poise and a strong sense of duty."

"She is a safe pair of hands," Ms Frank added.

"Kate has a Moon in Cancer which means she connects deeply with William - there is a fantastic equilibrium in their relationship and they perfectly balance one another."

Kate Middleton has been praised for her grace and dignity when taking part in royal duties.

Royal writer Penny Junor said Kate Middleton, 39, is 'absolutely extraordinary' and represents what a future Queen should be when she celebrated her 10th wedding anniversary with the Duke of Cambridge.

Experts also heaped praise on the wife of Prince William at the funeral of Prince Philip, when she was spotted chatting to Prince Harry, who was reportedly shunned by other members of the royal family.

Brian Hoey, who has written a biography of Prince William, told The Sun: “They say cometh the hour, cometh the man. But in the Royal Family's case, it’s a woman.

“Thank God for Kate — she is the rock the monarchy will depend on. On Saturday, she behaved absolutely impeccably.”
