Prince William and wife Kate Middleton have paid tribute to Prince Philip following his death aged 99 on Friday.
The Duke and Duchess of Cambridge updated their official website, The Royal Foundation of the Duke and Duchess of Cambridge, with a black-and-white portrait of a smiling Philip.
It reads simply: "HRH The Duke of Edinburgh. 1921- 2021."
They also published the official royal family statement, which was released at the time of Philip's death on April 9.
Meanwhile, Princess Anne paid tribute to her father today, saying he was "my teacher, my supporter and my critic" in a message following his death at the age of 99.
"You know it's going to happen but you are never really ready.
"My father has been my teacher, my supporter and my critic, but mostly it is his example of a life well lived and service freely given that I most wanted to emulate.
"His ability to treat every person as an individual in their own right with their own skills comes through all the organisations with which he was involved.
"I regard it as an honour and a privilege to have been asked to follow in his footsteps and it has been a pleasure to have kept him in touch with their activities. I know how much he meant to them, in the UK, across the Commonwealth and in the wider world.
"I would like to emphasise how much the family appreciate the messages and memories of so many people whose lives he also touched. We will miss him but he leaves a legacy which can inspire us all."
It came after Prince Andrew, Prince Edward, his wife, Sophie, Countess of Wessex and their daughter, Lady Louise, 17, attended a small church service at the Royal Chapel of All Saints in Windsor.
Prince Philip "passed away peacefully" at Windsor Castle on Friday. His death follows a recent four week stay in hospital and heart surgery. He was discharged and returned home on March 16.
"It is with deep sorrow that Her Majesty The Queen has announced the death of her beloved husband, His Royal Highness The Prince Philip, Duke of Edinburgh," the royal family announced in a statement.
On Sunday (NZT) Prince Charles made an emotional on-camera statement in which he spoke of his family's "sorrow".
Charles said he missed his father "enormously" and the Duke would be "so deeply touched" by the outpouring of grief.
"I particularly wanted to say that my father, for 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," Prince Charles told ITV in a video statement from Highgrove, Gloucestershire.
"As you can imagine, my family and I miss my father enormously," Charles added.
"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.
"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."
Buckingham Palace announced that Prince Philip's ceremonial royal funeral would take place on April 17 at St George's Chapel in Windsor Castle.
However, while Prince Harry will travel to the UK to be with his family for the service, his wife Meghan will remain at their US home.
The Palace confirmed in a statement that the Duchess of Sussex, who is pregnant with her and Harry's second child, was "advised not to travel" by her doctor.
Instead, Harry will make the journey alone from California where he will follow Covid-19 protocols for the trip, as well as during his visit.
A source close to Meghan reportedly said she made "every effort" to go.
"The Duchess has made every effort to travel alongside The Duke, but unfortunately, she did not receive medical clearance from her physician," they told royal journalist Omid Scobie.
The trip marks the first time Harry will return to the UK, since March of 2020, when he and Meghan left after stepping back from their duties as senior working members of the royal family.
It will also be the first time Harry sees his family in person, following he and Meghan's bombshell interview with Oprah, where they accused the royal family of racism.
