The Duke of Edinburgh died on Friday morning just two months before his 100th birthday, with tributes quickly pouring in from across the world.
World leaders including US president Joe Biden paid commended his service, charity work and dedication to the Queen.
The duke’s grandson, who now lives with his family in Montecito, California, is expected to fly back to the UK to attend his grandfather’s funeral, which will be pared back due to the pandemic.
To mark Prince Philip’s death, the Duke and Duchess of Sussex placed the following words on their company Archewell’s website: “In loving memory of His Royal Highness The Duke of Edinburgh 1921-2021
“Thank you for your service… You will be greatly missed.”
Amid speculation about whether they will attend the Duke’s funeral, Angela Levin, a royal biographer, told PA: “I wonder if Prince Harry will come over, I would imagine he would.”
“I don’t expect Meghan to,” she added, citing her pregnancy as a reason for her not to travel for the ceremony.
Similarly, a source close to the royal family told The Daily Mail on Friday that Prince Harry will “absolutely do his utmost” to be with his family at “this awful time”.
The comments come a month on from the couple’s divisive interview with Oprah Winfrey, in which they opened up about the difficulties of their life in the UK.
The Duke of Edinburgh’s funeral is likely to take place on Saturday 17 April, with details expected to confirmed this weekend.
In ordinary times, there would have been a military procession in London to mark Prince Philip’s time in the Navy and a funeral attended by world leaders.
However, things will be different because of the coronavirus, with funerals currently limited to a maximum of 30 people, who have to be socially distanced if they are not from the same household or bubble.
Royal commentator Joe Little said he believed the Duke would have approved of this, as he “didn’t want all the pomp and pageantry”.
According to his wishes, Prince Philip’s coffin will not lie in state.
