The Queen's death sent shockwaves through the nation as Buckingham Palace announced that Her Majesty passed away peacefully in her residence at Balmoral yesterday (8 September).
"The Queen died peacefully at Balmoral this afternoon," a statement read.
"The King and The Queen Consort will remain at Balmoral this evening and will return to London tomorrow."
King Charles III ascended to the throne immediately upon the death of Elizabeth II.
While these are unprecedented times for most of us, as the Queen's reign began way back in 1952, there's a series of protocols which are expected to take place in the coming days.
Friday, 9 September
King Charles III and Camilla will return to London, where the King is likely to meet Earl Marshal – the Duke of Norfolk – who is in charge of the accession and the Queen’s funeral, to approve plans.
Charles will then decide the length of national mourning – the period of royal mourning has been announced from now until seven days after the Queen's funeral.
The King is expected to have an audience with Prime Minister Liz Truss.
Charles will also be expected to give his first address as King this evening.
At around 1:00pm, there will be Gun salutes – one round for every year of the Queen’s life – which will be fired in Hyde Park and at other stations.
There will later be a service at St Paul’s Cathedral.
The prime minister and senior ministers will also attend a public service of remembrance at St Paul’s in central London.
Saturday, 10 September
Charles will officially be proclaimed King and the first public proclamation of the new sovereign will be read in the open air from the Friary Court balcony at St James’s Palace by the Garter King of Arms.
Proclamations will also be held around the country as Union flags go back up to full-mast at 1:00pm and remain there for 24 hours to coincide with the proclamations - before returning to half-mast.
The King will host audience with PM and Cabinet.
