The Queen 's coffin has arrived in Edinburgh, where large crowds are expected to gather to pay their respects before it is flown to London.
Later today, the coffin will be taken from the Palace of Holyroodhouse to nearby St Giles' Cathedral in a solemn procession attended by King Charles III, his sister Anne, brothers Edward and Andrew and Camilla, the Queen Consort.
Senior royals will also attend a vigil at the city's historic cathedral.
The coffin will then Lie at Rest in St Giles' - located in the Old Town of Edinburgh - where people will be able to see it in just a few hours.
Mourners will be allowed to file past the coffin from around 5.30pm today until 3pm tomorrow.
Due to large crowds, people have been told they might need to stand in long queues - and there might be delays on public transport.
There will also be local and major road closures, with no parking available near the cathedral.
The queue of mourners will start at George Square Lane/North Meadow Walk in The Meadows, where each person will receive one wristband.
Only people wearing wristbands will be able to enter St Giles and see the late monarch's coffin.
Flowers can be laid in Middle Meadow Walk and Palace of Holyrood House but will not be permitted into St Giles Cathedral.

Visitors will only be allowed to take one bag measuring 40x30x20 and there are no facilities for bag drops in the security area.
The use of mobile phones or other handheld devices is prohibited in the security search are or within St Giles Cathedral.
Step-free access is available and guide dogs, hearing dogs and other official assistance dogs are permitted, it has been confirmed.
In the early evening of Tuesday, the coffin will =be flown in a Royal Air Force aircraft to London, where well-wishers will be able to see it at Westminster Hall from Wednesday.
It will be guarded 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 September 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."
