Finding Freedom, the eagerly awaited book about the British and Sussex royal family, has claimed that there was a disagreement between Meghan Markle and the Queen herself.

Meghan and the Queen disagreed about Markle's choice of wedding day tiara, but Meghan has blamed Her Majesty's personal dresser, Angela Kelly, for the disagreement.

At the time, it was reported that Meghan wanted to wear an emerald tiara, but the Queen had selected a diamond tiara worn by her grandmother, Queen Mary, in 1932 instead.

The authors of Finding Freedom, Omid Scobie and Carolyn Durand, claim that Prince Harry felt like Angela was dragging her feet while trying to help decide on what tiara to wear.

At the time of the row, The Queen is said to have told Prince Harry, according to a Royal insider: "Meghan cannot have whatever she wants. She gets what tiara she's given by me."

"The Queen also questioned why Meghan needed a veil for the wedding, given it was to be her second marriage", the insider alleged, adding that: "Meghan can be difficult".

Angela Kelly has worked with the Queen since 2002 and has risen quickly through the ranks to become her personal assistant and senior dresser.

Another book has claimed that Prince Harry was "petulant and short-tempered" in his book Charles At Seventy: Thoughts, Hopes and Dreams.

He allegedly told staff with a raised voice: "What Meghan wants, Meghan gets" and when reports of his "tiresome behaviour" reached the Queen who asked to see her grandson privately and she 'put him firmly in his place', Mr Jobson wrote.

However, Meghan said that the Queen Mary DIamond Bandeau was the "perfect" choice for her wedding as she spoke at an exhibition where the tiara was being displayed.

"When it came to the tiara on the day, I was very fortunate to be able to choose this gorgeous art deco style bandeau tiara.

"Harry and I had gone to Buckingham Palace to meet with Her Majesty The Queen to select one of the options that were there, which was an incredibly surreal day as you can imagine.

"And that was the one that, I think, as we tried them on, stood out."    

Speaking about the tiara she eventually chose, she continued: "I think it was just perfect because it was so clean and simple - and also to that point, an extension of what Clare and I had been trying to do with the dress which was have something that could be so incredibly timeless but still feel modern."
