The royal family has released details of the plan for Queen Elizabeth II's funeral, and it's full of tradition, protocol and logistics.

The plan for the Queen's death is code-named Operation London Bridge, but another plan called Operation Unicorn is taking place to transport her body from Balmoral Castle in Scotland.

Over the next 10 days, we will see these carefully choreographed plans swing into action.

A timeline of Operation Unicorn, and what comes next

The Queen died at Balmoral Castle in north-east Scotland. It was her summer home and one of her favourite places.

Her coffin currently rests within the ballroom of the castle.

On Wednesday afternoon, a procession with the King's Troop, Royal Horse Artillery, will take the coffin from Buckingham Palace to Westminster Hall.

The process will pass The Mall, Horse Guards, Whitehall, Parliament Square and New Palace Yard before it arrives at Westminster Hall.

Once at Westminster, a service will be held by the Archbishop of Canterbury and the King and members of the royal family will attend.

The Queen's body will lie in state in Westminster Hall — where members of the public will be able to visit — for four days until the morning of the state funeral.

September 19: The Queen's funeral takes place

At 11am on Monday, September 19, the Queen's body will be taken from the Palace of Westminster to Westminster Abbey for the state funeral.

The Abbey is where the Queen had her coronation, and where she married Prince Philip.

The Queen's body will then be taken to St George's Chapel at Windsor Castle where she will be buried next to her husband, Prince Philip.

The pair will join the Queen's parents, King George VI and the Queen Mother, as well as the Queen's sister Princess Margaret.

Where are royal family members right now? 

Earlier, King Charles and the Queen Consort were at St James's Palace in London where he was officially proclaimed as King.

His proclamation was witnessed by dignitaries and his son, Prince William.

The Queen's other three children — Anne, Edward and Andrew — and their families were still at Balmoral.

The group attended a short church service before walking back up to the gates of Balmoral Castle, thanking people who had gathered.

Prince Andrew's appearance was notable because he had been largely excluded from royal duties after allegations of sexual assault.

Princes William and Harry, and their wives Catherine and Meghan, were earlier at Windsor Castle where they made a joint appearance to greet people at the gates.
