The route that the Queen's coffin will take from Wellington Arch to Windsor Castle for the committal service on Monday afternoon has been revealed - with thousands of people expected to turn out.
The state funeral takes place in Westminster Abbey at 11am that day, and then just after 1pm at the Arch, the coffin will be transferred from the gun carriage to the hearse which will leave London for Berkshire.
It will travel west along the south edge of Hyde Park before passing through Queens Gate and heading along Cromwell Road.
Continuing through the capital, it will pass Hammersmith and Chiswick along the north bank of the River Thames.
Taking the Great South West Road it will pass south of Heathrow Airport - under silent skies after a slew of flight cancellations - as it leaves London and goes past Staines.
The Queen's coffin will enter the grounds of Windsor Castle through Shaw Farm Gate and head north before finally arriving at St George's Chapel for the service which begins at 4pm.
Interest in saying goodbye to the Queen has been huge, with tens of thousands queuing to see the monarch lying in state at Westminster Hall.
It has been 70 years since the death of the previous monarch, Queen Elizabeth II's father George VI, so the vast majority of people in the UK are unaccustomed to the traditions and pageantry that have been on display over the last few days.
Tens of millions of people around the world are expected to watch as the Queen's funeral takes place.
Procession at Windsor
As the coffin arrives in Windsor there will be a procession as it makes its way towards the chapel.
Walking behind the gun carriage will be King Charles, Princess Anne, Prince Andrew and the Earl of Wessex.
Behind them will walk royal brothers Prince William and Prince Harry, as well as Peter Phillips.
Further back, a royal car will carry the Queen Consort and the Princess of Wales, and a second will carry the Duchess of Sussex and the Countess of Wessex.
