EDINBURGH - Britain's King Charles will fly to Edinburgh to join his siblings on Monday when the coffin of his mother Queen Elizabeth is taken in a solemn procession from one of her Scottish palaces to the city's historic St Giles cathedral.
The new monarch will also join senior royals for a vigil at the church where the coffin will lie at rest before being flown to London on Tuesday.
Since Elizabeth's death aged 96 at Balmoral Castle, her Scottish holiday home, a carefully choreographed series of plans to mourn Britain's monarch of 70 years has been put into operation.
On Sunday, her oak coffin, draped in the Royal Standard of Scotland with a wreath on top, was taken by hearse on a six-hour journey from Balmoral through picturesque Scottish countryside, villages, small towns and cities to Edinburgh.
Tens of thousands of well-wishers lined the roads to pay their respects, while huge crowds, some in tears, gathered in Edinburgh to greet the cortege.
"It's just very sad," said Rachel Lindsay, 24. "I don't think we expected it to ever happen. I just thought she'd live forever. I didn't think it was real until I saw it."
Before setting off for Scotland, Charles, 73, who automatically became king of the United Kingdom and 14 other realms of including Australia, Canada, Jamaica, New Zealand and Papua New Guinea, will travel to the British parliament for another traditional ceremony.
At Westminster Hall, lawmakers from both the House of Commons and the upper House of Lords will express their condolences for the death of his mother, and the new king will deliver a response.
He will then fly to Edinburgh with his wife Camilla, the Queen Consort, to join his sister Anne, and brothers Andrew and Edward.
The queen's children will then walk in a procession behind the hearse as the coffin of their mother is taken to St Giles'Cathedral, flanked by soldiers.
Crown of Scotland
When it arrives at the church, the Duke of Hamilton and Brandon, the premier Scottish peer, will place the Crown of Scotland on the coffin.
After a service, the coffin will rest at the cathedral for 24 hours to allow people to pay their respects. A continuous vigil will be mounted by soldiers from the Royal Company of Archers - the sovereign's 'Body Guard in Scotland'.
Charles, who will also visit the Scottish parliament and meet Scotland's First Minister Nicola Sturgeon, will later mount a vigil at 7.20pm along with other royals.
On Tuesday, the coffin will be flown to London where on Wednesday it will begin a period of lying in state until early on Sept 19 - the day of Elizabeth's state funeral - on a catafalque at Westminster Hall.
It will be guarded constantly by soldiers or by Yeoman Warders - known as beefeaters - from the Tower Of London.
Members of the public will be allowed to process past the coffin, which will be covered by the Royal Standard with the sovereign's Orb and Sceptre placed on top, for 24 hours a day until 6.30am on Sept 19.
"Those wishing to attend will be required to queue for many hours, possibly overnight," the government said in a statement. "Large crowds are expected and people are encouraged to check ahead, plan accordingly and be prepared for long wait times."
Meanwhile thousands of people are continuing to gather at royal palaces across Britain, bringing bouquets of flowers. In Green Park near London's Buckingham Palace, where some of the tributes are being taken, long lines of bouquets now snake around the park allowing mourners to read the tributes.
Other well-wishers have attached their messages of condolence to trees.
Britain last saw such an display of public mourning in 1997 following the death of Charles's first wife, Princess Diana, after she was killed in a car crash in Paris.
"It reminds me of Diana 25 years ago," Helen Soo, 59, said. "I was much younger in those days, I slept overnight in Hyde Park and this is multiplied by 100 probably." REUTERS
