The service will be at 3pm on Monday. Members of the public, friends, Royal Family members and representatives from the charities and organisations the Queen was affiliated with in Scotland are expected to attend.
The Queen’s coffin will be borne in procession from the Palace of Holyroodhouse to St Giles’ Cathedral flanked by The King’s Bodyguard for Scotland (Royal Company of Archers) and the Guard of Honour.
Minute guns will be fired as the procession makes its way up the Royal Mile. The last round will fire as the hearse stops outside St Giles’ Cathedral.
It has also been revealed the cortege is expected to leave Balmoral Castle on Royal Deeside at 10am on Sunday.
Scottish First Minister Nicola Sturgeon said the “poignant” journey, which will see the Queen’s coffin transported to the Palace of Holyroodhouse, would give the public a chance to come together to “mark our country’s shared loss”.
She added: “It will be especially poignant to see Her Majesty’s coffin begin its journey from her Aberdeenshire home to the Palace of Holyroodhouse in Edinburgh.
“This is a chance for people to gather together publicly and begin to mark our country’s shared loss.”
The First Minister said authorities anticipate many people will be keen to pay their respects and urged them to observe public safety messaging to ensure everyone’s safety.
Transport Scotland operations manager Stein Connelly warned road closures on Sunday could result in delays and disruption.
After the coffin arrives at the Palace of Holyroodhouse on Sunday, it will rest in the Throne Room.
On Monday, it will travel in a procession to St Giles’ Cathedral along the Royal Mile with the King and the late Queen’s other children, Princess Anne, the Duke of York and the Earl of Wessex, following on foot, along with Admiral Sir Tim Laurence.
Camilla, now Queen Consort, and the Countess of Wessex will follow by car and also attend the service in St Giles’.
Meanwhile, the Earl Marshal, the Duke of Norfolk, announced the Queen’s state funeral will take place at Westminster Abbey on September 19 at 11am.
Government sources revealed schools will close on the day of the funeral, giving thousands of youngsters the chance to watch the televised service and pay their respects.
Further details were confirmed on Saturday on the carefully choreographed London Bridge plans, which will include a four-day lying in state at Westminster Hall from September 14.
The Queen’s oak coffin is currently lying at rest in the Ballroom at Balmoral Castle covered in a Royal Standard of Scotland with a wreath of flowers on top.
Elizabeth II will lie in state for “four clear days” in Westminster Hall, arriving there in the afternoon of September 14, until 6.30am on the morning of her funeral, a senior palace official said.
