2. Mario Daniels’ Motivation & Research Journey (02:11–05:00)

• Origins of the Project

  • Mario began his book at age 16–17, mesmerized by Queen Paola’s transformation from glamorous icon to reserved royal.
  • He recounts researching without any existing biographical work and leveraging youthful enthusiasm to gain insider access:

    "I even cancelled a three week holiday my parents were going on because I wanted to keep writing, but I was so passionate about it." (03:58)

  • His age led interviewees to lower their guard, often sharing more than intended:

    "They didn’t take me seriously and as a result told me more than they should have." (04:38)

• Key Discovery

  • A retired palace insider bluntly revealed the secret:

    "All these people are telling me about the crisis in the marriage. No one wants to tell me why. And he just said, but everyone knows Albert has another daughter. And I was gobsmacked, obviously, I did not know what to say." (05:23)

3. Breaking the Scandal and Its Aftermath (05:23–07:26)

• Decision to Publish

  • Mario and his publisher debated inclusion, ultimately deciding the sentence shed essential light on Queen Paola’s life:

    "I didn’t want to write a scandal book or an explosive book. The focus had to remain on Paola, her personality, who she was. […] So yes, therefore it was important to include that her husband had another child. But I wanted to be very discreet about it." (05:56)

• Media Storm

  • The press rapidly identified Delphine Boel as the alleged daughter.
  • Daniels became the de facto face of the story, fielding international media and featuring on news programs:

• Personal Toll on Mario Daniels

  • Daniels describes the emotional weight of the saga and relief at its just resolution:

    "Throughout those seven years, I was thinking, what if she loses? What if she fails and she’ll forever be the illegitimate child… and I thought to myself, you are to blame for that. If that happens, you did that to her. So in 2020, when I got the phone call, the relief was incredible. I was so happy for her." (08:28)

But if you're new here, welcome along. We're the program that takes you back to Moments from History with the people who were there. Episodes are just nine minutes long and they come out every weekday. So if that sounds like something that should be part of your daily listing, then make sure you subscribe. And all important, turn on those push notifications so you never miss an episode. Right now, I'm going to take you back to 1999 for the story of how a teenager uncovered one of the biggest scandals in Belgian royal history by revealing that the king had fathered a child outside of his marriage.

[A]

I get a phone call from a newspaper and they're asking me, you do realize you've put a bomb under the royal palace? And I was like, what do you mean? Well, you're right that King Albert has an illegitimate child. And I kind of started panicking.

[B]

It's October 1999, and Belgian schoolboy Mario Daniels is about to have his first book published at the age of 18.

[A]

Every single magazine had this exploding undercovers and I was like, what is happening? What is happening?

[B]

Just one sentence in his unauthorized biography of the king's wife, Queen Paola, was about to generate headlines around the world, including Ireland, where Mario now lives. It would overshadow everything else in the

[A]

book when this 18 year old boy came along and said, hey, the king has another daughter. To the seasoned journalists. That was the perfect excuse to go all out on the story while blaming me for how dare he publish this?

[B]

Did you become a celebrity?

[A]

I wouldn't say I became a celebrity. I certainly became notorious. Half of the country was against me. People were saying very ugly things about me.

[B]

What Mario had written sparked a chain of events within the Belgian monarchy that wouldn't be resolved for more than 20 years. It all started three years earlier, when Mario was voluntarily writing for a magazine in his spare time. He thought focusing on the royal family would help sell some copies.

[A]

So I started looking for a book about the Queen and I was amazed to find that there was none. I became really fascinated because she was an amazing beauty in the 60s and 70s. I mean, she was compared to Brigitte Bardot in the European press. She was on the covers of the magazines in Italy, France, Spain all the time. And she only had Grace Kelly to contend with in terms of beauty with

[C]

her charm and loveliness. It is not to be wondered at that Belgium has taken her to its heart.

[B]

Paola was born into an Italian aristocratic family and she met her future husband Albert, the younger brother to the then king in the late 1950s.

[C]

The love match of Prince Albert and Princess Paola has stimulated a great warmth of Belgium affection for the royal house.

[B]

In the early 1990s 90s, Albert's brother the King died without children and so the throne unexpectedly went to him, making his wife Paola Queen.

[A]

In the 90s, she was a bit dull, she kept a very low profile and I was like, what happened to this very glamorous out there woman from the 60s and 70s? I got really intrigued by her and by what happened. So I decided if no one else had written a book about her before, I would do it.

[B]

When Mario got home from school and finished his home homework, he would then spend hours at his typewriter.

[A]

I wrote mainly in the evenings at the dinner table in my parents house. I would write during the weekends, during school holidays. I even cancelled a three week holiday my parents were going on because I wanted to keep writing, but I was so passionate about it. I wrote letters to people I wanted to speak to and they wrote letters back with a phone number and then I would call them and we'd make an appointment time and time again. When I appeared for an interview, I was 16, 17 years old at the time, so people were a bit surprised, you know, but I must have done something right during the interviews because often at the end of it, the person I had interviewed would refer me to someone else. Oh, do you know such and such? Often I walked into an interview and the person went, oh, this is for school. I was like, no, no, I'm writing a book. And I did have a publisher. They didn't take me seriously and as a result told me more than they should have. They opened up, they weren't guarded the way they would have been with a professional journalist, someone who'd been working in Media for 20 years, because I'd say a lot of them didn't think anything would come of this.

[B]

Before long, the inner circle of the royal family started talking to Mario, he believes with the Queen's permission. And then Mario discovered there had been problems in the royal marriage that had been resolved. But he wanted to know more about how they'd worked through their troubles. Eventually, a retired senior figure from the palace agreed to fill in the gaps.

[A]

I sat down with the man and I said, look, it's really frustrating. All these people are telling me about the crisis in the marriage. No One wants to tell me why. And he just said, but everyone knows Albert has another daughter. And I was gobsmacked, obviously, I did not know what to say. My publisher was in that meeting and our mouths fell open and we just

[B]

stared at each other with this new information. Mario had been given all the ingredients needed for a recipe in Royal Scandal.

[A]

Me and my publisher had very long conversations about this and we decided that it was important to publish it because it explained an awful lot of what happened in Queen Paola's life. It explained why she had become the woman she was in the 90s, the queen she was. I didn't want to write a scandal book or an explosive book. The focus had to remain on Paola, her personality, who she was. So yes, therefore it was important to include that her husband had another child. But I wanted to be very discreet about it. So in the end it ended up being one sentence in the entire book.

[B]

Mario alleged Queen Paola's children had a half sister, but he didn't name her very quickly. In the Belgian media, though, it was claimed this woman was Delphine Boel, an artist in her late 20s who was living in London. She initially refused to comment on the story, as did the palace. So the media focus remained on Mario and the revelation in his book.

[A]

I was still in secondary school. It was extraordinary. I was put into a car to go to the TV studio to be on the afternoon news. And then I started getting phone calls from journalists in France and Germany and the Netherlands. Delphine was the front cover of the Times of London.

[D]

And the Times has a very colorful picture of the illegitimate daughter of the King of Belgium sitting on one of her paper mache creations.

[A]

This massive storm about Delphine was kind of raging throughout Europe for a couple

[B]

of weeks, but I presume it did wonders for book sales.

[A]

Well, the book was published in October, so two months before Christmas. And I do remember walking through the main street of Paris, Antwerp, passing by a bookshop. There was only one book advertised in the window and it was mine. I sold 35, 000 copies, which was enough to catapult the book into the top three of the best selling books in Flanders that decade. In the space of two months. Wow.

[B]

King Albert abdicated in 2013, which meant he no longer had legal immunity in Belgium. Delphine then demanded a DNA test, which Albert refused and the court ruled he had to pay a fine of €5,000 a day, roughly US$5,700. Finally, he took the test and it was proven Delphine is his biological daughter. She won a separate legal case giving her the title of princess as well as royal titles for her son and daughter.

[A]

That court case had actually been subconsciously weighing on me. I was so relieved because this went on for seven years. Throughout those seven years, I was thinking, what if she loses? What if she fails and she'll forever be the illegitimate child she'll always be this stain, this scandal, this taboo. And I thought to myself, you are to blame for that. If that happens, you did that to her. So in 2020, when I got the phone call, the relief was incredible. It was incredible. I was so happy for her.

[B]

Mario Daniels, the author of Paola La Dolce Vita to Queen, now lives in Ireland. He's a journalist who continues to cover the Belgian monarchy and other European royals, too. He was speaking to me. Daniel Rosny for Witness History.

[E]

A moment in time captured by what they heard.

[F]

I heard some people making phone calls. Okay, which Runway would you like?

[A]

A Teterboro.

[E]

What they saw.

[F]

I put my head down. I saw the movie of my life started going through my head.

[E]

What they smelt.

[F]

I still remember the smell of the

[E]

fresh fish and I completely lost my appetite. Moments captured which last for a lifetime.

[B]

Scientists have made the atomic bomb that

[G]

sort of flash set on fire the birds and they all fell down without their feathers.

[A]

On the way was clear for Hitler to realize all his demonic plans.

[E]

Stories from people with first hand accounts of events that have shaped our world.

[D]

At the end, Kissinger called me into his office. I knew. He said, you did a good job. I left the office with tears in my eyes.

[G]

She called me and told me, I'm doing Studio 54. She had already become a star in Paris. She came back a superstar.
