Princess Diana's death was one that rocked the nation, and sparked a national outpouring of grief. But of course, none were hit more by the devastating news than her two sons, Prince William and Prince Harry.
Until this year, the two royals had remained resolutely silent on speaking about their mother's death. But recently, the pair have opened up, speaking about the difficult moments surrounding their beloved mother's death, and how they are determinedly keeping her memory alive.
In what is set to be one of the most emotional documentaries about the late Princess of Wales so far, Prince William and Harry are opening up about the heartbreaking moments after they learnt of their mother's death, and the difficult days that followed.
In a new BBC Princess Diana documentary, Diana, 7 Days, set to air on Sunday 27th August, the Princes finally speak about the moment the news of their mothers death was broken to them.
Praising their father, Prince Charles, for his strength following the news, Prince Harry said, "One of the hardest things for a parent to have to do is to tell your children that your other parent has died.
"But he was there for us, he was the one out of two left and he tried to do his best and to make sure we were protected and looked after.
"But, you know, he was going through the same grieving process as well."
And speaking about the utterly heart-wrenching moment Charles told him Diana has died, William explained how he felt, "disorientated, dizzy... and very confused".

He continued, "I remember just feeling completely numb. And you keep asking yourself ‘why me?' all the time. ‘What have I done?'"
Harry describes his reaction too as being one of utter "disbelief", revealing the fact that, for him, there was no "sudden outpouring of grief".
In the aftermath of the tragic news, Harry and William retreated to the monarch's Balmoral estate in Scotland in order to gain some much needed privacy.
But speaking about the moment they returned to London for the funeral, Harry described how alarming the scale of the national grief felt to him at the time.
He explained, "People were grabbing us and pulling us into their arms and stuff. I don't blame anyone for that, of course I don't. But it was those moments that were quite shocking. People were screaming, people were crying, people's hands were wet because of the tears they had just wiped away from their faces before shaking my hand."

William also spoke about the funeral, explaining how he used his then-long fringe to hide away from the crowds whilst walking behind Diana's coffin.
He said, "I just remember hiding behind my fringe basically, at a time when I had a lot of hair, and my head's down a lot."
"It was kind of like a tiny bit of safety blanket if you like. I know it sounds ridiculous, but at the time I felt if I looked at the floor and my hair came down over my face, no one could see me.
"Sounds ridiculous now, but at the time it was important to me to get through the day."

He added that walking behind his mother's coffin left him feeling torn "between me being Prince William and having to do my bit, versus the private William who just wanted to go into a room and cry, who'd lost his mother."
The BBC documentary will also feature interviews from Tony Blair, Prime Minister at the time, Diana's sister, and other prominent figures. Reportedly, this is the final time the boys will open up in such intimate detail about the events surrounding their mother's death.
