Queen Elizabeth II reportedly has a secret diary and the only one who's allowed to read it is her husband, Prince Philip. She's reportedly writing in her diary every night, where she details about the people she met, the places she's been, as well as her private thoughts.

A royal insider claims Queen Elizabeth ensures her journal would be kept as a top secret and she reportedly told royal aides to destroy the blotting paper she used to absorb the ink from the pen. In addition, Her Majesty reportedly asked everyone to leave her alone when she's writing unless a "world-shattering" incident happens - like nuclear war.

In a report from The Sun, the insider said the monarch uses a pad of blotting paper after she completed her entry. And every morning, one of the first duties of her personal Page will reportedly destroy the blotting paper so that no one would be tempted to try and read a reverse impression of what she wrote.

Moreover, Queen Elizabeth reportedly doesn't miss a night and she takes her diary with her wherever she goes. The insider claims the monarch takes the journal with her, whether she's at Windsor, Sandringham, or Balmoral, and it was kept in a black leather case.

As per the insider, the Queen's diary has never gone missing, largely because it was considered almost as valuable to her as the Crown Jewels. Meanwhile, the newly-knighted actor Michael Palin also revealed Her Majesty's love of journaling.

He recalled how he found out the Queen also has a diary; it was when he got invited for a night at Windsor Castle and was seated next to the monarch during dinner. During those times, Palin said he mentioned about a nightly journal where he wrote about the people he encountered, and Her Majesty said she did that too.

The only difference is that his journals have been for publication, while hers weren't. After the dinner, Palin shared that he and the other guests got the chance to have a tour at the royal library, wherein Queen Elizabeth pointed out the diary of her father, King George V.

According to Huge Vickers, a historian and royal author, Her Majesty found out she loves journaling during her teenage years, which was after she watched her father write his own. He claims Queen Elizabeth was once asked by a bishop if she writes in her own hand, and she riposted she couldn't write in in anyone else's.
