According to BBC, the Queen's four children, Charles, Anne, Andrew and Edward, went to Scotland when it was announced that the Queen was under medical supervision. Her grandson, Prince William, also went to Balmoral Castle. In the afternoon came the news of her death. Her 70-year reign makes Elizabeth the longest-reigning British Queen in history.
With her death, her eldest son, Prince Charles, will assume the throne as King of the United Kingdom and 14 other countries where the British monarch is head of state, such as Australia and Canada.
