Prince Harry has spoken of the difficulty of living up to people's expectations around the world when following in the footsteps of his well-travelled grandmother the Queen.
The Prince said he could think of nowhere on the planet that the monarch had not been as he was interviewed for ITV's Our Queen at Ninety documentary to mark the sovereign's 90th birthday.
"People have always said 'Do you feel as if you're following in her footsteps?' Well that's exactly what we are doing.
"There is nowhere on this planet that I can think of that she hasn't been in the last 90 years.
"She's been everywhere," Harry said.
"Sometimes it's quite hard because you go to a place where she hasn't visited for maybe 20, maybe 15 years and you just think to yourself 'How could I ever fulfil this huge expectation that comes with her and being a member of her family?'"
In new footage released from the programme, which will be broadcast on Easter Sunday at 8pm, the Queen is seen inspecting Buckingham Palace ballroom ahead of a state banquet.
The monarch tells an aide how the microphones for the delivery of speeches, which are now discreetly hidden in the floral displays, used to be brought out and put in place in a very different way.
Gesturing with her hand, the Queen recalls: "In the old days you see, they used to march them up the middle and plonk them down in front."
She is also shown preparing to tackle state papers at her desk in the palace. She places her handbag on her chair, puts on her glasses and stands as she uses a key to open her red box containing the official documents.
On her desk is her adjustable day, date and month brass calendar, which sits in front of youthful photographic portraits of both her mother the Queen Mother and father George VI.
The Countess of Wessex, one of the many royals interviewed for the programme, talks about the need for the monarch's outfits to catch people's attention.
"Don't forget that when she turns up somewhere, the crowds are, two, three, four, 10, 15 deep and somebody wants to be able to see that they saw a bit of the Queen's hat as she went past," Sophie said.
"She needs to stand out for people to be able to say, 'I saw the Queen'."
