Grandson Prince William, 33, pays tribute to his grandmother, saying: "Growing up, having this figurehead, having this stability above me has been incredible. I have been able to explore, understand, slightly carve my own path. I greatly appreciate and value that protection."

As for how members of the public react to meeting his grandma, he added: "A lot of people get very excited and sort of nervous around her. And I've seen some very comical moments. I've seen people literally faint in front of her. It's quite a startling moment as to what to do when you faint in front of the Queen! There's a lot of trembling knees and people can't talk sometimes. It's quite difficult talking to people when they can’t talk. You don't get very far; I don't get past the 'Hello's."

His brother Prince Harry, 31, praised Queen Elizabeth's devotion to her duties and to the Commonwealth – whose membership has grown to 53 nations during her reign.
He said: "I look at the Commonwealth and think, 'Look how much it's achieved'... She should be incredibly proud of what she's led and what she’s achieved and what she's created amongst a huge amount of people from different ethnic backgrounds, different skin colors, different experiences, different islands – whatever it be. Hats off to her, it's incredible."

The Queen made her first visit to a Commonwealth country – South Africa – in 1947, where she celebrated her 21st birthday and made her historic broadcast pledging her "whole life, whether it be long or short" to her people.
Harry noted: "It's just incredible to know that someone at that age appreciated and understood exactly what was expected of them and to basically put duty ahead of everything else so early on in her life is quite remarkable." He joked: "I have been asking her for years what her secret is, but she won't tell me."

Princess Eugenie, the 25-year-old daughter of the Queen's son Prince Andrew and his ex-wife Sarah, Duchess of York, talks in the documentary about how "Granny" can truly be herself on her beloved Scottish estate, Balmoral. "It's the most beautiful place on Earth," said Eugenie. "I think Granny is the most happy there, I think she really, really loves the Highlands… Walks, picnics, dogs – a lot of dogs, there's always dogs! – and people coming in and out all the time.

"Family-wise we're all there, so it's a lovely base for Granny and Grandpa to be – for us to come and see them up there, where you just have room to breathe and run."
Of her grandfather, the Duke of Edinburgh, Eugenie added: "I think Grandpa is incredible. He really is strong and consistent. He's been there for all these years, and I think he's the rock, you know, for all of us."
The Queen has a total of eight grandchildren: Prince William, 33; Prince Harry, 31; Peter Phillips, 38; Zara Phillips, 34; Princess Beatrice, 27; Princess Eugenie, 25; Lady Louise Windsor, 12; and eight-year-old James, Viscount Servern.
