AceShowbiz - Representatives for Britain's royal family are urging fans to consider making charity donations in Prince Philip's memory instead of leaving flower tributes outside Buckingham Palace.

Queen Elizabeth II's husband, the Duke of Edinburgh, died on Friday (09Apr21), aged 99, and palace officials are encouraging people to avoid crowding at the London landmark due to ongoing COVID-19 concerns, instead asking those wishing to honour the prince to donate to a worthy cause.

"During this time the royal family ask that members of the public consider making a donation to a charity instead of leaving floral tributes in memory of The Duke of Edinburgh," they state.

"With the safety and wellbeing of the public in mind, and in accordance with Government guidelines, members of the public are asked not to gather in crowds. Those wishing to express their condolences are asked to do so in the safest way possible, and not to gather at Royal Residences..."

"An online Book of Condolence for those who wish to leave messages is available on the royal website."

Despite the royal request, some members of the public still headed to Buckingham Palace to mourn the duke's passing, with many laying bouquets at the venue's gates, where police officers were stationed to ensure social distancing guidelines were obeyed.

In the wake of Prince Philip's passing, U.S. President Joe Biden offered condolences to the Queen and royal family, "(First Lady) Jill and I are keeping the Queen and Prince Philip's children, grandchildren, and great-grandchildren in our hearts during this time."

Meanwhile, Barack Obama described the Duke as "kind and warm, with a sharp wit and unfailing good humor."

Grandson Prince Harry and wife Meghan Markle who are miles away in the U.S. posted a message in his honour on their Archewell website.

It reads, "In loving memory of His Royal Highness The Duke of Edinburgh. 1921-2021. Thank you for your service... you will be greatly missed."
