he plans for the funeral of the Duke of Edinburgh have been meticulously prepared over many years under the code name Operation Forth Bridge.
At the personal insistence of Prince Philip there will not be a state funeral or a public lying in state but instead a far lower-key event known officially as a royal ceremonial funeral.
Following today’s announcement the Queen is expected to give her formal approval to the details of the funeral plans to the Lord Chamberlain, Baron Parker of Minsmere — ex-head of MI5 — who took over the role at the start of the month.
Under the original plan, thousands would have been expected to flock to London and Windsor for a military procession of Philip’s coffin on the day of his funeral.
Hundreds of members of the armed forces would have been called upon to line the streets in honour of the duke, along with hundreds of police officers to keep control of crowds and protect the members of the royal family taking part.
However, with restrictions still in place amid the Covid-19 outbreak, the public elements of the final farewell to the Queen’s consort will not be able to take place in their original form.
Organisers are said to be “desperately anxious” not to stage anything that attracts mass gatherings, one source said.
From the onset of the pandemic, planners have been busy behind the scenes working out a contingency strategy in case the duke died during the crisis — a worst-case scenario of major concurrent events — a fear that has come true.
Preparations are expected to centre on Windsor Castle, without the military procession in London or any processions through Windsor.
But the exact final arrangements will depend on how the UK is coping with the outbreak and the current R value — the number of people to whom an infected individual passes on the virus.
The duke, who was vaccinated against coronavirus in January, spent much of 2020 and the start of 2021 at Windsor Castle after moving from the Sandringham estate in Norfolk to stay with the Queen ahead of the start of the first lockdown.
Current rules on funerals in England mean only a maximum of 30 people may attend, and they must socially distance if they do not live together or share a support bubble.
It is likely there will be some military involvement to honour the duke’s service to the armed forces.
This will probably be socially distanced and in the confines of Windsor Castle’s grounds.
World leaders and Commonwealth representatives, as well as foreign royals, former and current politicians and military chiefs, would have been among those due to be invited to gather at the funeral, but such arrangements will now be impossible. Much depends on the guidance issued to the royal household from the Government over the next few days.
The fact that there will be no lying in state for the duke, which would have involved thousands of members of the public queuing to view his coffin, eases some of the potential problems.
For the Queen Mother, who had a lying in state, some 11,887 police staff and 1,306 civil staff were deployed from the day of her death to the funeral, a Metropolitan Police report on the cost of policing public order events during 2002 disclosed.
The police will now have the task of ensuring crowds do not gather to pay their respects.
The Forth Bridge plans have been in place for many years and were updated and reviewed regularly by Buckingham Palace staff in consultation with both the Queen and Philip.
A memorial service — not something the duke wanted — could be held at a later date after the nation has dealt with the worst public health crisis for a generation.
The Lord Chamberlain, Baron Parker, is the most senior official of the royal household and has overall responsibility for the duke’s funeral.
Baron Parker will be closely supported by the Lord Chamberlain’s Office, other senior officials at Buckingham Palace and relevant government departments — most likely the Cabinet Office and the Ministry of Defence.
The Lord Chamberlain’s Office, which is independent of the Lord Chamberlain, will be working around the clock on the arrangements for the funeral. Based usually at Buckingham Palace, the team — headed by the Queen’s Comptroller — is tasked with the practical side of the day.
Lieutenant Colonel Michael Vernon, who served in the Coldstream Guards, became the Comptroller in 2019.
The Office draws up funeral plans years in advance, covering a variety of scenarios, so as to be ready in the event of a royal death.
Sir Edward Young, the Queen’s private secretary and senior adviser, will be on hand for the Queen throughout the challenging days ahead.
He is responsible for supporting the Queen in her duties as head of state and is the channel of communication between the Queen and Government.
The funeral service is likely to be conducted by the Archbishop of Canterbury, the Dean of Windsor and representatives from other chapels and is expected to be televised by the BBC.
There is likely to be a private committal service in St George’s Chapel with the coffin going into a royal vault until the Queen dies, when both will be buried in the King George VI memorial chapel in St George’s.
