Death of Queen Elizabeth II: What happens next?
Monday, September 12
King Charles III and his wife Camilla, now Queen Consort, visit parliament, to receive condolences from the speakers of the lower and upper houses, before delivering a reply.
The royal couple fly to Edinburgh and at the Palace of Holyroodhouse the king will take part in the Ceremony of the Keys, where he will symbolically receive -- and then return -- the keys to the city.
In the afternoon, the king and other royals take part in a procession to convey the queen's coffin along Edinburgh's Royal Mile to St Giles' Cathedral, before a religious service.

After his first audience with Scotland's First Minister Nicola Sturgeon and a visit to the Scottish parliament, Charles III returns to St Giles' to take part in a vigil over the coffin -- known as the Vigil of the Princes -- with other family members.
From 5:30 pm (1630 GMT) until 3:00 pm on Tuesday, members of the public can file past to pay their respects as the coffin lies at rest guarded by the Royal Company of Archers.
The king and his wife will be joined in Scotland -- and on his tour of Northern Ireland and Wales -- by Prime Minister Liz Truss, Downing Street said.
"It's not a requirement," Truss's spokesman told reporters.
"But the prime minister believes it's important to be present for what will be a significant moment of national mourning around the United Kingdom."
