King Charles arrived at Buckingham Palace for the first time as monarch and met with some of his subjects waiting outside, as the crowd hailed God Save the King.
The former Prince of Wales became the new sovereign as soon as his mother, Queen Elizabeth II, died yesterday afternoon at the age of 96.
In a whirlwind 24 hours Charles and the rest of the family rushed to Balmoral to be at her bedside before her sad passing.
