The doors of Westminster Abbey have opened ahead of the state funeral of Britain’s longest-reigning monarch, Queen Elizabeth II, the BBC reports.
King Charles III will lead a somber procession behind his mother’s coffin on the short journey from Westminster Hall to the Abbey later.
The first state funeral to be held since Sir Winston Churchill’s in 1965 will begin at 11:00 BST.
It marks the end of 10 days of events across the UK since the Queen’s death.
As London prepares for as many as one million visitors for the historic occasion, roads and bridges are closed to traffic and an unprecedented security operation is under way.
Before the service begins, the Queen’s coffin will be conveyed – in the first of three processions throughout the day – through Parliament Square, a distance of about 820ft (250m).
The Prince of Wales and the Duke of Sussex will once more walk side-by-side behind their father, the King, who will walk alongside his siblings, the Queen’s four children.
Two of the Queen’s great-grandchildren, Prince George, nine, and Princess Charlotte, seven, will also walk behind the Queen’s coffin in procession.
The State Gun Carriage will carry the coffin, drawn by 142 sailors. A guard of honour will stand in the square made up of all three military services, accompanied by a Royal Marines band.
Some 2,000 mourners will bid farewell to the Queen at the state funeral, including 500 dignitaries – with presidents, prime ministers and foreign royalty among the guests.
