She was perhaps the most famous of the six sisters who dominated British high society in the 1930s.
Unity Mitford was a debutante, a socialite and, most controversially, a raging anti-Semite who worshiped Adolf Hitler.
Now, in a world exclusive, the Daily Mail has tracked down the diary that Unity kept while winning the affections of the Nazi dictator.
For the past eight months, a team led by Sandra Parsons, the Mail’s literary editor, has been working on the project to publish Unity’s private musings for the first time.
A Mail podcast that premiered yesterday reveals Unity’s own words in great detail, allowing listeners to make up their own minds about her scandalous life.
Over the course of four episodes, Hitler’s English Bride: The Secret Diary of Unity Mitford explores every salacious detail recorded by the debutante.
It also delves into the horrible hatred of Jews that Unity repeatedly expressed. His words are, as our literary editor says, “relentlessly and chillingly anti-Semitic.”
And to dispel any doubts about its authenticity, the diary has been subjected to rigorous testing by a forensic science laboratory.

Now, in a world exclusive, the Daily Mail has tracked down the diary that Unity kept while winning the affections of the Nazi dictator.
Unity became known as ‘Hitler’s English Bride’ because of how close she came to the monstrous dictator.
They saw each other dozens of times, including in their Munich apartment. Their closeness sparked suggestions that the pair may even have had a sexual relationship.
As the Mail podcast reveals, Unity left tantalizing clues in her diary that her bond with Hitler may have been more than platonic.
The first episode of the podcast details how Unity came to fall in love with Hitler and asks why, as the clouds of war gathered over Europe, the Nazi leader spent time alone with a woman half his age.
The series then goes on to explore how Unity went from a sought-after newcomer to a committed fascist and anti-Semite.
It also reveals Unity’s revelations about Hitler’s mental state in the lead-up to the conflict with Britain.
The fact that Unity was, like her five sisters, very beautiful probably helped her in her attempt to win the affections of Hitler and the good books of other prominent Nazis.
She became so close to the Führer himself that she came to be seen as a rival by his long-time girlfriend, Eva Braun, who wrote that her boyfriend’s photographer had told her he had a “replacement” for her.

Unity Mitford sat with Nazi leader Julius Streicher (left) at the 1938 Nuremberg rally.
But when Britain declared war on Germany on September 3, 1939, after Hitler ordered the invasion of Poland, Unity was left desperate.
She was so distraught that she decided to take her own life in the most horrible way.
Unity took a gun to the English Garden in Munich and shot himself in the head.
But surprisingly, the debutant survived. She received the best medical care on Hitler’s orders and was then flown back to Britain.
Unity died eight years later as a result of the brain damage he suffered from the initial gunshot wound. But that was not the end of the story.
More than 50 years later, explosive claims emerged that Unity may have been pregnant with Hitler’s child when she returned to England seriously injured.

Unity sat down with top Nazis. The fact that Unity was, like her five sisters, very beautiful probably helped her in her attempt to win Hitler’s affections.
An article in the New Statesman reported on the theory that she may have secretly given birth in a nursing home in rural Oxfordshire and then given her child up for adoption.
There was never any definitive proof of the claims.
But, as the Mail’s new podcast reveals, Unity grew close enough to Hitler that they were more than friends behind closed doors.
