Queen Elizabeth II's personal Coronation message revealed ahead of King Charles's ceremony

The letter was handwritten by Elizabeth in 1937.

Elizabeth signed the letter 'Lilibet' in reference to her nickname within the Royal Family.

Royal Family captioned the Instagram post showing the letter: "Today, as we look at King George VI Coronation in 1937 as part of our #MonarchMonday series, we’re featuring a very special memory of the day from the eleven-year-old Princess Elizabeth, later Queen Elizabeth II.

"The front cover of her account is visible here, and we’ve shared a quote below, as well as a photo of the young princess in her Coronation dress standing with her parents, King George VI and Queen Elizabeth, and sister, Princess Margaret."

Elizabeth wrote on the front cover of the letter: "To Mummy and Papa
In Memory of Their Coronation
From Lilibet

By Herself"

The letter continued: "I thought it all very, very wonderful and I expect the Abbey did, too.

"The arches and beams at the top were covered with a sort of haze of wonder as Papa was crowned, at least I thought so."

Queen Elizabeth II's Coronation took place on June 2 1953.

King Charles, aged four, attended his mother's Coronation.

Earlier this month, it was confirmed that Prince Harry would attend Charles's Coronation without Meghan.

King Charles is 'understanding' of Meghan Markle's decision not to come to his Coronation, according to a source.

A source told The Sun: "Harry was desperate to come back for the Coronation and spend quality time with his family."

Sources added that there is a "willingness and wanting to mend on both sides."
