Prince Philip had three requests before he passed away, which he relayed to his eldest son, Prince Charles.
While Philip was away, Charles — who was the only one of Philip's children to visit him in the hospital — had a "full and frank" and "heartfelt" discussion, a royal source told the outlet.
Charles was supposedly in touch with his father via telephone and in person before he passed away; the last time he saw him was on Tuesday, April 6.
One day after Philip's death, Charles shared a sweet message about his father.
"I particularly wanted to say that my father, for I suppose the last 70 years, has given the most remarkable, devoted service to The Queen, to my family and to the country, but also to the whole of the Commonwealth," the 72-year-old said in a statement, which was captured on camera.
"As you can imagine, my family and I miss my father enormously. He was a much loved and appreciated figure and apart from anything else, I can imagine, he would be so deeply touched by the number of other people here and elsewhere around the world and the Commonwealth, who also I think, share our loss and our sorrow," Charles continued.
He concluded, "My dear Papa was a very special person who I think above all else would have been amazed by the reaction and the touching things that have been said about him and from that point of view we are, my family, deeply grateful for all that. It will sustain us in this particular loss and at this particularly sad time. Thank you."
