The Duke of Edinburgh will be honoured with a three minute silence at 3pm on Saturday April 17.
All public elements of the funeral have been cancelled, it will be televised but take place entirely in the grounds of Windsor Castle, Buckingham Palace said.
The funeral, which under normal circumstances would be attended by 800 people, will take place in St George’s Chapel.
The service will be attended by just 30 people, in keeping with Covid restrictions, with the Queen and her family following social distancing guidelines and wearing face masks.
The Palace spokesman said: “While there is sadness that the public will not be able to physically be part of events to commemorate the life of the duke, the royal family asks that anyone wishing to express their condolences do so in the safest way possible and not by visiting Windsor or any other royal palaces to pay their respects.”
Palace spokesman said the Royal Family hoped the coming days would be seen as a chance to celebrate the duke’s “remarkable life”.
“While this is naturally a time of sadness and mourning for the royal family and the many others who knew or admired the Duke of Edinburgh, it is hoped that the coming days will also be seen as an opportunity to celebrate a remarkable life – remarkable both in terms of his vast contribution and lasting legacy,” the spokesman said.
Paying tribute to the duke’s military record, his passion for science, engineering, design, art, the armed forces and charities, the spokesman added: “You can see why his influence is so much greater than many may imagine the role of the consort to be.”
“The Covid-19 pandemic has of course required us to make significant adaptations to the original arrangements for His Royal Highness’s funeral,” the spokesman added.
“However, we are certain that the occasion will be no less fitting a farewell to His Royal Highness, marking his significant duty and service to the nation and the Commonwealth.”
Buckingham Palace announced Prince Philip’s death on Friday and released details of his funeral on Saturday afternoon.
The duke’s coffin will be transported from the castle to the chapel in a specially modified Land Rover he helped to design, and followed by the Prince of Wales and senior royals on foot, a senior Palace official said.
The Queen has approved the Prime Minister’s recommendation of national mourning, which began on April 9 and runs until and including the day of the funeral.
It is understood the Duchess of Sussex made every effort to be able to travel with Harry, who will be among the mourners, but has not received the medical clearance to board a plane.
