Charles has become Britain’s new King following the death of his mother, Queen Elizabeth II, at the age of 96.
The Queen became the sixth female to ascend to the British throne in February 1952, after the death of her father, King George VI. She was the longest-reigning monarch in British history, serving for more than 70 years.
Charles, the Queen’s eldest son, immediately ascended to the throne as King, putting his elder son, William, first in line for the throne.
