The King, his sons, Princes William and Harry, and other senior royals joined a solemn procession behind the Queen's coffin as the late monarch made her final journey from Buckingham Palace.
Huge crowds gathered in central London to witness the Queen being taken from the palace to parliament as artillery guns fired salutes and Big Ben tolled, the latest in a series of poignant ceremonies as the nation mourns the Queen who died last week aged 96 after seven decades on the throne.

Lying on a gun carriage, covered by the Royal Standard flag and with the Imperial State Crown placed on a cushion on top alongside a wreath of flowers, the coffin bearing the Queen's body was taken in a slow, sombre procession from her London home to Westminster Hall. There it will lie in state for four days.

Walking directly behind were the King and his siblings, Anne, Andrew and Edward. In a group that followed were the King's sons, Princes William and Harry.
"It was very moving, seeing the family," said Jenny Frame, 54, who waited for more than four hours to see the procession. "I think it's very fitting for her."
Hushed silence
A military band playing funeral marches and soldiers in ceremonial scarlet uniforms, some with shiny silver breastplates and helmets, accompanied the gun carriage pulled by the King's Troop, Royal Horse Artillery, as it moved slowly through central London, where many roads were closed to traffic.
Guns fired every minute at Hyde Park, while parliament's famous Big Ben bell also rang at 60-second intervals. The crowds stood in a hushed silence as they watched the procession but then broke into spontaneous applause when it passed. Some threw flowers.
Other senior royals including the King's wife, Camilla, now the Queen Consort, Kate, William's wife and now Princess of Wales, and Harry's wife, Meghan, travelled by car.
When the procession reached Westminster Hall, a medieval building with origins dating back to 1097 and the oldest part of the Palace of Westminster that houses the British parliament, the coffin was carried inside by soldiers from the Grenadier Guards and placed on a catafalque surrounded by candles.

A short service followed, conducted by the Archbishop of Canterbury, the spiritual head of the Anglican Church, as senior politicians watched on. The royals quietly departed, with Prince Harry and his wife, Meghan, holding hands.
A constant vigil will be held by soldiers in full ceremonial uniforms at the four corners of the catafalque.
Just after 5pm, the public began to file past the coffin, some in tears, many bowing their heads. There will be a constant stream of mourners, 24-hours a day, during the four days of lying in state that lasts until the morning of the funeral on Sept. 19.
"We've lost someone special," said Kenneth Taylor, 72, who stayed overnight in a tent to be one of the first in the queue. He said a lump had come to his throat as he viewed the Queen lying in state.
"Her service to this country was steadfast and unswerving."
A Buckingham Palace spokesperson said Elizabeth had three keys roles in her life: head of the family, head of the nation and head of state. Wednesday marked the moment the coffin passed from the family to the state.
Long queue
People started waiting in line overnight, sleeping on the street in the rain, to be one of the first to file past the coffin, and there was already a queue more than 2 miles long.
"We didn't even think about it," said Glyn Norris, 63, adding a bit of rain would not deter her.
"That was my Queen."
Among those gathered, some were there to represent elderly parents, others to witness history and many to thank a woman who, having ascended the throne in 1952, was still holding official government meetings just two days before she died.
The government has warned the queue could stretch for up to 10 miles (16 kilometres) along the southern bank of the River Thames, winding past landmarks such as the giant London Eye ferris wheel.
British Culture Secretary Michelle Donelan said some people might have to stand in line for as long as 30 hours in order to file past the coffin before Monday's funeral.
"She's an icon of icons," mourner Chris Imafidon said. "I must at least endure this camping out of respect."
Speaking to people in the queue, the Archbishop of York Stephen Cottrell, quipped:
"We are honouring two great British traditions, loving the Queen and loving a queue."
The Queen's coffin was flown back to London from Scotland, where it had been since her death at her Scottish summer holiday home Balmoral Castle, where tens of thousands of people lined the 14-mile (22-km) route in driving rain.
In Scotland, about 33,000 people filed past the coffin during the 24 hours it was at St Giles' Cathedral in Edinburgh, but the memorial in London is a much larger occasion.
As many as 750,000 mourners are expected to walk through Westminster Hall to pay their final respects.
A senior palace official described the poignant pageant as relatively small and personal. The full-scale ceremonial procession on the day of her funeral is likely to be one of the biggest the country has ever witnessed.
Royalty, presidents and other world leaders are expected to attend, although no one from certain nations, such as Russia, Afghanistan, and Syria will be invited.

US President Joe Biden, who has said he would be there, spoke to the King, the White House said, and "conveyed the great admiration of the American people for the Queen".
"We're seeing something very sad but very special," said Charlie Cooper, 51, who had travelled by coach from Liverpool, northern England, to watch the ceremony. "It's part of my history, and millions of others around the world."
